EPIacuteGRAFE

O talento precisa ser trabalhado

A vocaccedilatildeo natildeo sobrevive sem que nossas

Cabeccedilas se curvem sobre livros e livros

A coragem tem que encher o peito

A vontade tem que pulsar na veia

A cabeccedila precisa estar aberta ao aprendizado

Por mais que estudemos sabemos pouco

Perto do que saberemos E jamais tudo

Tudo a nossa volta pode nos ensinar algo

Estaacute formando eacute um grande contentamento

Mas natildeo encerra a busca

Por aperfeiccediloamento profissional

Muito menos o ideal da profissatildeo

Fazer o maacuteximo pelo proacuteximo

da inclinaccedilatildeo no VO2max no protocolo de rampa O objetivo desse estudo foi comparar o

VO2max medido durante o protocolo de rampa em esteira sem inclinaccedilatildeo (0) e com

inclinaccedilatildeo fixa (6) mas com incrementos de velocidades iguais Participaram deste

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

pareado (0 versus 6) atraveacutes do software estatiacutestico Statistica 70 para Windows Todos

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

17

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

ANEXO A

About the Brazilian Journal of Medical and Biological Research

The Brazilian Journal of Medical and Biological Research is an open-access journal

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

EPIacuteGRAFE

O talento precisa ser trabalhado

A vocaccedilatildeo natildeo sobrevive sem que nossas

Cabeccedilas se curvem sobre livros e livros

A coragem tem que encher o peito

A vontade tem que pulsar na veia

A cabeccedila precisa estar aberta ao aprendizado

Por mais que estudemos sabemos pouco

Perto do que saberemos E jamais tudo

Tudo a nossa volta pode nos ensinar algo

Estaacute formando eacute um grande contentamento

Mas natildeo encerra a busca

Por aperfeiccediloamento profissional

Muito menos o ideal da profissatildeo

Fazer o maacuteximo pelo proacuteximo

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

pareado (0 versus 6) atraveacutes do software estatiacutestico Statistica 70 para Windows Todos

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

17

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

ANEXO A

About the Brazilian Journal of Medical and Biological Research

The Brazilian Journal of Medical and Biological Research is an open-access journal

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

EPIacuteGRAFE

O talento precisa ser trabalhado

A vocaccedilatildeo natildeo sobrevive sem que nossas

Cabeccedilas se curvem sobre livros e livros

A coragem tem que encher o peito

A vontade tem que pulsar na veia

A cabeccedila precisa estar aberta ao aprendizado

Por mais que estudemos sabemos pouco

Perto do que saberemos E jamais tudo

Tudo a nossa volta pode nos ensinar algo

Estaacute formando eacute um grande contentamento

Mas natildeo encerra a busca

Por aperfeiccediloamento profissional

Muito menos o ideal da profissatildeo

Fazer o maacuteximo pelo proacuteximo

da inclinaccedilatildeo no VO2max no protocolo de rampa O objetivo desse estudo foi comparar o

VO2max medido durante o protocolo de rampa em esteira sem inclinaccedilatildeo (0) e com

inclinaccedilatildeo fixa (6) mas com incrementos de velocidades iguais Participaram deste

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

pareado (0 versus 6) atraveacutes do software estatiacutestico Statistica 70 para Windows Todos

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

17

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

About the Brazilian Journal of Medical and Biological Research

The Brazilian Journal of Medical and Biological Research is an open-access journal

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

EPIacuteGRAFE

O talento precisa ser trabalhado

A vocaccedilatildeo natildeo sobrevive sem que nossas

Cabeccedilas se curvem sobre livros e livros

A coragem tem que encher o peito

A vontade tem que pulsar na veia

A cabeccedila precisa estar aberta ao aprendizado

Por mais que estudemos sabemos pouco

Perto do que saberemos E jamais tudo

Tudo a nossa volta pode nos ensinar algo

Estaacute formando eacute um grande contentamento

Mas natildeo encerra a busca

Por aperfeiccediloamento profissional

Muito menos o ideal da profissatildeo

Fazer o maacuteximo pelo proacuteximo

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

pareado (0 versus 6) atraveacutes do software estatiacutestico Statistica 70 para Windows Todos

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

17

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

The Brazilian Journal of Medical and Biological Research is an open-access journal

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

EPIacuteGRAFE

O talento precisa ser trabalhado

A vocaccedilatildeo natildeo sobrevive sem que nossas

Cabeccedilas se curvem sobre livros e livros

A coragem tem que encher o peito

A vontade tem que pulsar na veia

A cabeccedila precisa estar aberta ao aprendizado

Por mais que estudemos sabemos pouco

Perto do que saberemos E jamais tudo

Tudo a nossa volta pode nos ensinar algo

Estaacute formando eacute um grande contentamento

Mas natildeo encerra a busca

Por aperfeiccediloamento profissional

Muito menos o ideal da profissatildeo

Fazer o maacuteximo pelo proacuteximo

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

pareado (0 versus 6) atraveacutes do software estatiacutestico Statistica 70 para Windows Todos

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

17

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

Resumo

A utilizaccedilatildeo do protocolo de rampa tem aumentado nas uacuteltimas deacutecadas uma vez que o

mesmo tem uma relaccedilatildeo mais linear entre carga de trabalho e consumo de oxigecircnio e a

possibilidade de individualizaccedilatildeo da intensidade Ateacute hoje nenhum estudo avaliou o efeito

da inclinaccedilatildeo no VO2max no protocolo de rampa O objetivo desse estudo foi comparar o

VO2max medido durante o protocolo de rampa em esteira sem inclinaccedilatildeo (0) e com

inclinaccedilatildeo fixa (6) mas com incrementos de velocidades iguais Participaram deste

estudo 11 homens jovens fisicamente ativos saudaacuteveis que foram submetidos a trecircs

sessotildees de exerciacutecios progressivos maacuteximos utilizando o protocolo de rampa em esteira

numa sequecircncia balanceada Foram mensurados o lactato sanguiacuteneo (La) frequecircncia

oxigecircnio (VO2pico) foi maior a 6 (527 plusmn 81 mLkg-1

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

Resumo

A utilizaccedilatildeo do protocolo de rampa tem aumentado nas uacuteltimas deacutecadas uma vez que o

mesmo tem uma relaccedilatildeo mais linear entre carga de trabalho e consumo de oxigecircnio e a

possibilidade de individualizaccedilatildeo da intensidade Ateacute hoje nenhum estudo avaliou o efeito

da inclinaccedilatildeo no VO2max no protocolo de rampa O objetivo desse estudo foi comparar o

VO2max medido durante o protocolo de rampa em esteira sem inclinaccedilatildeo (0) e com

inclinaccedilatildeo fixa (6) mas com incrementos de velocidades iguais Participaram deste

estudo 11 homens jovens fisicamente ativos saudaacuteveis que foram submetidos a trecircs

sessotildees de exerciacutecios progressivos maacuteximos utilizando o protocolo de rampa em esteira

numa sequecircncia balanceada Foram mensurados o lactato sanguiacuteneo (La) frequecircncia

cardiacuteaca maacutexima (FCmax) consumo de oxigecircnio (VO2) produccedilatildeo dioacutexido de carbono

(CO2) volume expiratoacuterio (VE) e quociente respiratoacuterio (RER) O consumo pico de

oxigecircnio (VO2pico) foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63

mLkg-1

min-1

) (p=003) O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram

maiores em 0 (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

) do que em 6 (0851 plusmn 0209 min e

122 plusmn 14 Kmh-1

) (plt0001) Valores da FCmax La RER e VE natildeo foram diferentes entre

as sessotildees experimentais (pgt005) Conclui-se que a presenccedila da inclinaccedilatildeo a 6 induz

maiores valores do consumo pico de oxigecircnio do que 0 de inclinaccedilatildeo

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Resumo

A utilizaccedilatildeo do protocolo de rampa tem aumentado nas uacuteltimas deacutecadas uma vez que o

mesmo tem uma relaccedilatildeo mais linear entre carga de trabalho e consumo de oxigecircnio e a

possibilidade de individualizaccedilatildeo da intensidade Ateacute hoje nenhum estudo avaliou o efeito

da inclinaccedilatildeo no VO2max no protocolo de rampa O objetivo desse estudo foi comparar o

VO2max medido durante o protocolo de rampa em esteira sem inclinaccedilatildeo (0) e com

inclinaccedilatildeo fixa (6) mas com incrementos de velocidades iguais Participaram deste

estudo 11 homens jovens fisicamente ativos saudaacuteveis que foram submetidos a trecircs

sessotildees de exerciacutecios progressivos maacuteximos utilizando o protocolo de rampa em esteira

numa sequecircncia balanceada Foram mensurados o lactato sanguiacuteneo (La) frequecircncia

cardiacuteaca maacutexima (FCmax) consumo de oxigecircnio (VO2) produccedilatildeo dioacutexido de carbono

(CO2) volume expiratoacuterio (VE) e quociente respiratoacuterio (RER) O consumo pico de

oxigecircnio (VO2pico) foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63

mLkg-1

min-1

) (p=003) O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram

maiores em 0 (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

) do que em 6 (0851 plusmn 0209 min e

122 plusmn 14 Kmh-1

) (plt0001) Valores da FCmax La RER e VE natildeo foram diferentes entre

as sessotildees experimentais (pgt005) Conclui-se que a presenccedila da inclinaccedilatildeo a 6 induz

maiores valores do consumo pico de oxigecircnio do que 0 de inclinaccedilatildeo

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

Resumo

A utilizaccedilatildeo do protocolo de rampa tem aumentado nas uacuteltimas deacutecadas uma vez que o

mesmo tem uma relaccedilatildeo mais linear entre carga de trabalho e consumo de oxigecircnio e a

possibilidade de individualizaccedilatildeo da intensidade Ateacute hoje nenhum estudo avaliou o efeito

da inclinaccedilatildeo no VO2max no protocolo de rampa O objetivo desse estudo foi comparar o

VO2max medido durante o protocolo de rampa em esteira sem inclinaccedilatildeo (0) e com

inclinaccedilatildeo fixa (6) mas com incrementos de velocidades iguais Participaram deste

estudo 11 homens jovens fisicamente ativos saudaacuteveis que foram submetidos a trecircs

sessotildees de exerciacutecios progressivos maacuteximos utilizando o protocolo de rampa em esteira

numa sequecircncia balanceada Foram mensurados o lactato sanguiacuteneo (La) frequecircncia

cardiacuteaca maacutexima (FCmax) consumo de oxigecircnio (VO2) produccedilatildeo dioacutexido de carbono

(CO2) volume expiratoacuterio (VE) e quociente respiratoacuterio (RER) O consumo pico de

oxigecircnio (VO2pico) foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63

mLkg-1

min-1

) (p=003) O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram

maiores em 0 (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

) do que em 6 (0851 plusmn 0209 min e

122 plusmn 14 Kmh-1

) (plt0001) Valores da FCmax La RER e VE natildeo foram diferentes entre

as sessotildees experimentais (pgt005) Conclui-se que a presenccedila da inclinaccedilatildeo a 6 induz

maiores valores do consumo pico de oxigecircnio do que 0 de inclinaccedilatildeo

Introduccedilatildeo

A medida do consumo maacuteximo de oxigecircnio (VO2max) durante o exerciacutecio eacute um

importante paracircmetro para a determinaccedilatildeo da capacidade funcional no diagnoacutestico e

prognoacutestico de doenccedilas cardiovasculares e na prescriccedilatildeo de exerciacutecio fiacutesico (1) O VO2max

pode ser determinado atraveacutes de protocolos de estaacutegio uacutenico intermitentes ou progressivos

com a utilizaccedilatildeo da medida direta (anaacutelise de gases expirados) ou indireta (equaccedilotildees de

prediccedilatildeo e nomogramas) em diversos ergocircmetros como bicicleta esteira bancos e remo

(2) Em esteira existem diversos protocolos de exerciacutecios progressivos validados como

Ellestad (2) Bruce (3) Astrand (2) Balke (2) rampa (4) e Naughton (2) Em relaccedilatildeo agrave

utilizaccedilatildeo desses protocolos Myers e Bellin (5) reportaram que o protocolo de Bruce (3)

era o mais utilizado em ambiente clinico na deacutecada de 90 para a determinaccedilatildeo do VO2max

no Veterans Affairs Health Care System dos Estados Unidos (82) No entanto o

protocolo de Bruce (3) e alguns dos protocolos citados acima apresentam aumentos

graduais excessivos na carga de trabalho e duraccedilatildeo diferente da que eacute recomendada (de 8 a

12 minutos) para testes progressivos (6) aleacutem de natildeo serem individualizados o que

interfere na determinaccedilatildeo do VO2maacutex (7)

Whipp et al (4) foram os primeiros a descreverem o protocolo de rampa em

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

About the Brazilian Journal of Medical and Biological Research

The Brazilian Journal of Medical and Biological Research is an open-access journal

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

cicloergocircmetro o qual envolve aumentos progressivos constantes e individualizados na

carga de trabalho a cada minuto similar a uma rampa Originalmente esse protocolo foi

criado para ser realizado em bicicleta ergomeacutetrica com duraccedilatildeo entre 4-8 minutos

entretanto sofreu algumas adaptaccedilotildees tais como o desenvolvimento para outro ergocircmetro

(esteira rolante) e a possiacutevel utilizaccedilatildeo de softwares com controle automaacutetico da carga de

trabalho (7) O diferencial deste protocolo segundo Myers e Beliin (5) aleacutem da

11

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

6) A hipoacutetese eacute que os valores de VO2max seratildeo maiores na presenccedila da inclinaccedilatildeo

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

individualizaccedilatildeo da carga de trabalhoeacute uma maior linearidade entre consumo de oxigecircnio e

trabalho realizado e menor variabilidade na estimativa do VO2max Por exemplo Myers et

al (7) observaram um erro menor na prediccedilatildeo do VO2max atraveacutes do protocolo de rampa

em esteira quando comparado ao protocolo de Bruce (3)

A individualizaccedilatildeo dos paracircmetros de velocidade e do componente vertical

(inclinaccedilatildeo) da esteira no protocolo de rampa requer a utilizaccedilatildeo de nomogramas (8-9) ou

fatores subjetivos (idade sexo estado de treinamento entre outros) que predizem o estado

funcional do indiviacuteduo Esta individualizaccedilatildeo permite ampla variaccedilatildeo nos incrementos de

velocidade e do componente vertical podendo interferir no valor do VO2max No sentido

da avaliaccedilatildeo da inclinaccedilatildeo sobre o VO2max Mayhew e Gross (10) por exemplo antes da

criaccedilatildeo do protocolo de rampa observaram o efeito do componente vertical no VO2max

Os autores reportaram que a presenccedila do componente vertical (inclinaccedilatildeo final 84 plusmn 13 )

com velocidade inicial constante (entre 129 e 161 kmbullh-1

) resultou em VO2max maior do

que aumentos exclusivos de velocidade (0 de inclinaccedilatildeo e velocidade inicial entre 129 e

177 kmbullh-1

e incrementos de 08 kmbullh-1

a cada 2 minutos) No entanto foram utilizados

incrementos da carga de trabalho a cada dois minutos descaracterizando o protocolo de

rampa aleacutem desees incrementos serem usados de forma diferente entre as sessotildees

Diante do exposto nenhum estudo anterior avaliou o efeito da inclinaccedilatildeo no

VO2max no protocolo de rampa quando os incrementos de velocidades satildeo iguais Aleacutem

disso testar indiviacuteduos saudaacuteveis em protocolos sem o uso da inclinaccedilatildeo pode aproximar

da realidade de corrida e auxiliar no delineamento do protocolo de rampa Dessa forma o

objetivo do presente estudo eacute comparar o VO2max mensurado durante o protocolo de

rampa em esteira com incrementos iguais de velocidade com ou sem inclinaccedilatildeo fixa (0 e

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

Materiais e Meacutetodos

O projeto foi aprovado pelo comitecirc de eacutetica em pesquisa (0082009) e todos os

voluntaacuterios consentiram em sua participaccedilatildeo no estudo atraveacutes da assinatura de um Termo

de Consentimento Livre e Esclarecido (TCLE)

Amostra

Participaram do estudo 11 indiviacuteduos do sexo masculino com idade de 26 plusmn 5 anos

natildeo fumantes fisicamente ativos e saudaacuteveis de acordo com o Coleacutegio Americano de

Medicina Esportiva (2) Os mesmos tiveram que ser considerados aptos de acordo com o

questionaacuterio de prontidatildeo para a atividade fiacutesica (PAR-Q) e apresentaram menos de dois

fatores de risco para doenccedilas cardiacuteacas coronarianas (2)

Procedimentos

Os voluntaacuterios compareceram ao laboratoacuterio em duas ocasiotildees distintas sempre no

mesmo horaacuterio com roupas apropriadas para atividade fiacutesica No dia anterior agraves visitas foi

requerido ao voluntaacuterio registrar sua ingestatildeo alimentar e repeti-la nas seguintes sessotildees

experimentais consistindo em uma dieta rica em carboidrato Foram instruiacutedos a evitar a

praacutetica de atividade fiacutesica extenuante dormir no miacutenimo 8 horas e natildeo ingerir cafeiacutena

aacutelcool e diureacuteticos 24 horas antes do experimento Para minimizar o efeito da

desidrataccedilatildeo os voluntaacuterios foram orientados a ingerir 500 ml de aacutegua 2 horas antes do

iniacutecio do experimento (2)

13

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

Resultados

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

cardiacuteaca maacutexima percentual da frequecircncia cardiacuteaca maacutexima atingida e lactato sanguiacuteneo

natildeo foram diferentes entre as sessotildees experimentais com ou sem inclinaccedilatildeo

17

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

Durante a primeira visita os voluntaacuterios foram submetidos a uma avaliaccedilatildeo

antropomeacutetrica que consistiu nas medidas da massa e estatura corporal que foram realizadas

com a utilizaccedilatildeo de uma balanccedila analoacutegica com estadiocircmetro acoplado (Welmy 110)

Adicionalmente foram medidas sete dobras cutacircneas (triacuteceps subescapular axilar meacutedia

toraacutecica supra-iliacuteaca abdominal e coxa) utilizando um plicocircmetro analoacutegico (Sanny

Starrett) e o percentual de gordura corporal foi calculado (11) a partir do calculo densidade

corporal (12) Apoacutes estes procedimentos iniacuteciou-se a primeira sessatildeo experimental

Todas as sessotildees experimentais foram realizadas em uma sala com temperatura seca

entre 18degC e 21degC e umidade relativa do ar entre 32 e 66 Antes de iniciar cada sessatildeo

experimental a gravidade especiacutefica da urina do voluntaacuterio foi medida por um refratocircmetro

manual (Biobrix ndash modelo 301) para verificaccedilatildeo do estado de hidrataccedilatildeo A maacutescara do

analisador de gases (K4b2 Kosmed Italy) e um cardiofrequenciacutemetro (F4 Blk Polar)

foram afixados ao voluntaacuterio que permaneceu sentado durante 5 minutos Em seguida o

voluntaacuterio se dirigiu agrave esteira (RT 300 PRO Moviment e Inbrasport ATL Inbramed) onde

foi iniciado um periacuteodo de preparaccedilatildeo ao exerciacutecio correspondendo a uma caminhada leve

(3 minutos a 5 kmh) Apoacutes esse periacuteodo de preparaccedilatildeo iniciou-se o protocolo de rampa

com aumentos na velocidade sem (0) ou com inclinaccedilatildeo fixa (6) de acordo com a

sessatildeo experimental (velocidade meacutedia inicial de 58 kmh-1

com meacutedia de incrementos de

09 kmh-1

) O consumo de oxigecircnio e o dioacutexido de carbono expirado foram medidos a cada

respiraccedilatildeo atraveacutes do analisador de gases A frequecircncia cardiacuteaca foi medida e gravada

atraveacutes do sistema de telemetria do analisador de gases durante todo teste para a verificaccedilatildeo

da frequecircncia cardiacuteaca maacutexima atingida (FCmaacutex)

Os protocolos dos testes foram elaborados para terem uma duraccedilatildeo entre 8 e 12

minutos (6) Durante o teste os voluntaacuterios receberam estiacutemulos verbais padronizados dos

avaliadores para que permanecessem em atividade ateacute o limite maacuteximo percebido Todos os

14

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

8 mmolL-1

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

expiratoacuterio e frequecircncia cardiacuteaca maacutexima foram comparados utilizando o teste t de student

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

testes foram finalizados a pedido do voluntaacuterio (fadiga voluntaacuteria) ou se os pesquisadores

observassem algum risco para o mesmo Ao final do teste a fase de recuperaccedilatildeo da esteira

foi acionada (3 minutos a 5 kmh) Nos primeiros 30 segundos dessa fase foi coletada uma

amostra de sangue perifeacuterico da polpa do dedo para anaacutelise do lactato sanguiacuteneo

(AccutrendLactate Roche) Ao deixar a esteira o voluntaacuterio permaneceu sentado por um

periacuteodo de 10 minutos

O teste foi considerado maacuteximo quando pelo menos dois dos seguintes criteacuterios foram

atingidos valores maacuteximos do quociente respiratoacuterio ge 115 frequecircncia cardiacuteaca atingida ge

95 da frequumlecircncia cardiacuteaca maacutexima prevista para a idade (220-idade) e lactato sanguiacuteneo ge

(6) O VO2max foi determinado a partir da meacutedia de cada 7 respiraccedilotildees como

descrito por Robergs Dwyer e Astorino (13) sendo o valor maacuteximo dessa meacutedia

considerado o VO2max Para determinaccedilatildeo do consumo maacuteximo de oxigecircnio (VO2max) ou

consumo pico de oxigecircnio (VO2pico) foram adotados os criteacuterios de Astorino (14) Entre

cada sessatildeo experimental foi adotado o intervalo miacutenimo de 48 horas com o intuito de

minimizar o possiacutevel efeito do treinamento da sessatildeo experimental anterior As sessotildees

experimentais foram realizadas de forma balanceada

Anaacutelise estatiacutestica

Inicialmente foi realizada uma anaacutelise descritiva dos aspectos demograacuteficos dos

participantes Em seguida foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade

da distribuiccedilatildeo da amostra Os valores de VO2max quociente respiratoacuterio volume

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

sufficient hard data to be appreciated by the reader The Brazilian Journal publishes

unstructured abstracts

The abstract should briefly and clearly present the problem experimental approach new

results as quantitative data if possible and conclusions It should mention the techniques

used without going into methodological detail and mention the most important results

Abbreviations should be kept to a minimum and should be defined in both the Abstract and

text

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

As caracteriacutesticas antropomeacutetricas dos voluntaacuterios que participaram do presente

estudo foram massa corporal 776 plusmn 100 kg estatura 176 plusmn 6 cm e percentual de gordura

de 155 plusmn 7

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

ergomeacutetrica foi maior a 6 (527 plusmn 81 mLkg-1

min-1

) do que a 0 (492 plusmn 63 mLkg-

1min

-1) (figura 1)

Os paracircmetros avaliados durante os testes estatildeo apresentadas na tabela 1 A

velocidade final e a duraccedilatildeo dos testes foram maiores nos testes sem (0) do que com

inclinaccedilatildeo (6) Os valores de volume expiratoacuterio quociente respiratoacuterio frequecircncia

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

Em nenhum dos testes observou-se a presenccedila de platocirc no consumo de oxigecircnio

conforme descrito por Astorino (14) por isso faz-se aqui o uso do termo consumo pico de

oxigecircnio (VO2pico) O VO2pico medido durante o protocolo de rampa em esteira

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

Discussatildeo

O principal objetivo do presente estudo foi comparar o VO2max mensurado durante o

protocolo de rampa em esteira com incrementos iguais de velocidade com ou sem

inclinaccedilotildees fixas Os resultados observados demonstram que os voluntaacuterios atingiram

paracircmetros similares de esforccedilo maacuteximo em todos os testes (tabela 1) entretanto os valores

de VO2pico foram maiores na presenccedila da inclinaccedilatildeo a 6 (figura 1) Fatores relacionados

agraves diferenccedilas na biomecacircnica na corrida com e sem inclinaccedilatildeo aleacutem da ativaccedilatildeo de

muacutesculos acessoacuterios podem estar envolvidos com estas diferenccedilas Adicionalmente os

voluntaacuterios do presente estudo relataram que na ausecircncia da inclinaccedilatildeo haacute uma dificuldade

biomecacircnica na manutenccedilatildeo da velocidade nos testes e inseguranccedila quanto as altas

velocidades atingidas

Similar a este achado Mayhew e Gross (10) obtiveram nos testes com a presenccedila do

componente vertical um VO2max (690 plusmn 46 mLKg-1

min-1

) maior em comparaccedilatildeo aos

testes sem este componente (669 plusmn 53 mLKg-1

min-1

) com diferenccedila de 3 entres os

testes no presente estudo o valor do VO2max foi de 527 plusmn 81 mLkg-1

min-1

a 6 e

492 plusmn 63 mLkg-1

min-1

a 0 com diferenccedila entre os testes de 6 No entanto o

protocolo reportado por estes autores utilizou incrementos de intensidade a cada dois

minutos natildeo se caracterizando um protocolo de rampa e valores e incrementos de

velocidade diferentes entre as sessotildees isso pode ter influenciado o valor do VO2max

quando comparado ao presente estudo em que a diferenccedila percentual entre testes foi maior

O presente resultado pode ter ocorrido devido ao fato de que na presenccedila da

inclinaccedilatildeo alguns muacutesculos acessoacuterios como os que atuam na manutenccedilatildeo da postura

geram um consumo de oxigecircnio adicional (15) No entanto os resultados observados com a

presenccedila do componente vertical natildeo podem ser transpostos para protocolos que utilizam

18

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

Supported file types

The following file formats can be accepted Detailed information for each file type can be

found by clicking on individual links

bull All abbreviations must be defined in this footnote even if they are explained in the

text

bull Tables must be understandable without referring to the text

bull Each table should be on a separate page after the Reference section in the submitted

manuscript Tables occupying more than one printed page should be avoided if possible

bull Vertical and diagonal lines should not be used in tables instead indentation and

vertical or horizontal space should be used to group data

valores elevados de inclinaccedilatildeo Em alguns protocolos de exerciacutecios progressivos validados

em esteira haacute diferentes percentuais de inclinaccedilatildeo do inicio para o final do teste como

Ellestad (2) com inclinaccedilatildeo inicial de 10 e final de 15 Bruce (3) com inclinaccedilatildeo inicial

de 0 e final de 23 Astrand (2) com inclinaccedilatildeo inicial de 0 e final de 25 Balke (2)

com inclinaccedilatildeo inicial de 0 e final de 30 Nestes protocolos a fadiga localizada em

alguns muacutesculos da panturrilha poderaacute afetar o valor de VO2max jaacute que o voluntaacuterio pode

interromper o teste precocemente (16)

O tempo total de exerciacutecio e a velocidade final ateacute a fadiga foram maiores para a

sessatildeo experimental sem o componente vertical (1134 plusmn 140 min e 154 plusmn 21 Kmh-1

)

quando comparado com a sua presenccedila (0851 plusmn 0209 min e 122 plusmn 14 Kmh-1

(plt0001)

Isso ocorreu porque quando a inclinaccedilatildeo estaacute presente o trabalho eacute aumentado gerando um

estresse maior para os muacutesculos ativos No estudo de Taylor Buskirk e Henschel (15) foi

avaliado o efeito de diferentes inclinaccedilotildees utilizando o protocolo de Havard sobre o VO2

Foram feitos dois testes diferentes no teste sem inclinaccedilatildeo a velocidade foi aumentada a

cada estaacutegio com incrementos de uma milhah no teste com inclinaccedilatildeo a velocidade foi

mantida constante (7 milhash) havendo incrementos de 25 na inclinaccedilatildeo (0 25 5

75 e 10) Os autores observaram que o VO2max foi maior a 75 de inclinaccedilatildeo do que

com os outros valores Neste caso o valor de 75 fica proacuteximo ao valor de 6 observado

no presente estudo

Valores de FCmax lactato sanguiacuteneo quociente respiratoacuterio e volume expiratoacuterio

natildeo foram diferentes entre as sessotildees experimentais (pgt005) similar agrave estudos anteriores

como os de Myers et al (7-17) Mayhew e Gross (10) que compararam protocolos ou

situaccedilotildees diferentes e natildeo observaram diferenccedilas nos criteacuterios de determinaccedilatildeo de teste

maacuteximo mesmo com duraccedilatildeo e tempo diferentes

19

Os resultados do presente estudo permitem melhor encaminhamento no delineamento

do protocolo de rampa o que permite determinar valores de VO2max maiores jaacute que eacute

importante levar em conta o tipo de treinamento realizado pelo indiviacuteduo Por exemplo

indiviacuteduos que correm no plano ao fazerem um teste maacuteximo sem a presenccedila da inclinaccedilatildeo

teraacute neste o fator que leva em conta a especificidade do exerciacutecio entretanto para que haja a

determinaccedilatildeo de um VO2max maior a presenccedila da inclinaccedilatildeo se faz importante A decisatildeo

da presenccedila ou natildeo da inclinaccedilatildeo no protocolo de rampa deve ser considerada para que os

valores de VO2max fiquem proacuteximos do real natildeo interferindo na prescriccedilatildeo de exerciacutecios

fiacutesicos e no treinamento esportivo

Conclui-se que o VO2pico durante o protocolo de rampa eacute maior a 6 quando

comparado a 0 de inclinaccedilatildeo

About the Brazilian Journal of Medical and Biological Research

The Brazilian Journal of Medical and Biological Research is an open-access journal

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

The Brazilian Journal of Medical and Biological Research publishes original research

articles of outstanding scientific significance We will consider manuscripts of any length

30

we encourage the submission of both substantial full-length bodies of work and shorter

manuscripts that report novel findings that might be based on a limited number of

experiments The key criteria are that the research demonstrates clearly its novelty its

importance to a particular field as well as its interest to those outside that discipline and

conclusions that are justified by the data

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

The Brazilian Journal of Medical and Biological Research publishes original research

articles of outstanding scientific significance We will consider manuscripts of any length

30

we encourage the submission of both substantial full-length bodies of work and shorter

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

The Brazilian Journal of Medical and Biological Research publishes original research

articles of outstanding scientific significance We will consider manuscripts of any length

30

we encourage the submission of both substantial full-length bodies of work and shorter

manuscripts that report novel findings that might be based on a limited number of

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

ANEXO A

About the Brazilian Journal of Medical and Biological Research

The Brazilian Journal of Medical and Biological Research is an open-access journal

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

preliminary communication or in an unrefereed symposium this should be cited as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Please contact Reinaldo de Souza (bjournalfmrpuspbr) if you have any questions

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

The Brazilian Journal of Medical and Biological Research publishes original research

articles of outstanding scientific significance We will consider manuscripts of any length

30

we encourage the submission of both substantial full-length bodies of work and shorter

manuscripts that report novel findings that might be based on a limited number of

experiments The key criteria are that the research demonstrates clearly its novelty its

importance to a particular field as well as its interest to those outside that discipline and

conclusions that are justified by the data

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

The Brazilian Journal of Medical and Biological Research is an open-access journal

published by the Associaccedilatildeo Brasileira de Divulgaccedilatildeo Cientiacutefica and can be found at

wwwscielobrbjmbr The journal features articles of exceptional significance originality

and relevance in all areas of biological science Our audience is the Brazilian and

international scientific community

Criteria for Publication

The Brazilian Journal of Medical and Biological Research is highly selective in the

manuscripts that it publishes rejection rates are high To be considered for publication in

the Brazilian Journal of Medical and Biological Research any given manuscript must be

outstanding in the following ways Originality Importance to researchers in its field

Interest to scientists outside the field Rigorous methodology and substantial evidence for

its conclusions

Submission of a manuscript to the Brazilian Journal implies that the data have not been

published previously and will not be submitted for publication elsewhere while the

manuscript is under review

The following represent prior publication any printed material in excess of 500 words

describing results or methods of a submittedin press manuscript published tables or

illustrations that duplicate the content of a manuscript electronic manuscripts or posters

available via the Internet When part of the material in a manuscript has been presented as a

footnote on the title page and a copy should accompany the submitted manuscript

28

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

httpwwwscielobrbjmbrarticles searchsubject) to index the article

Running title

This short title to be used as a page heading should not exceed 60 letters and spaces

Abstract

Since abstracts are published separately by Information Services they should contain

sufficient hard data to be appreciated by the reader The Brazilian Journal publishes

unstructured abstracts

The abstract should briefly and clearly present the problem experimental approach new

results as quantitative data if possible and conclusions It should mention the techniques

used without going into methodological detail and mention the most important results

Abbreviations should be kept to a minimum and should be defined in both the Abstract and

text

38

Please do not include any reference citations in the abstract If the use of a reference is

unavoidable the full citation should be given within the abstract

The abstract should not exceed 250 words and should be written as a single paragraph

double-spaced on a separate page following the title page

Please see lthttpwwwbjournalcombrwriting_a_good_abstracthtmlgt for suggestions on

writing a good abstract

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

Publication Charges

The authors are responsible for publication charges of all accepted papers Publication

charges will be billed to the Corresponding Author when the paper is accepted

The charge is R$145000paper for Brazilian authors and US$80000paper for authors

outside Brazil and is independent of the length of the paper

The Journal does not provide reprints to corresponding authors They will receive a CD

containing the issue in which the paper is published There is no charge for figures in color

Overview of the Editorial Process

Our aim is to provide all authors with an efficient courteous constructive and just editorial

process To ensure the fairest and most objective decision-making the editorial process is

run as a partnership between the Brazilian Journal of Medical and Biological Research

editors and the editorial board which is comprised of leaders in all fields of medicine and

biology

In situations in which authors are unsure whether their paper is within the scope of the

journal and satisfies the basic requirements for publication in the Brazilian Journal of

Medical and Biological Research we are happy to consider presubmission enquiries

Responses to these enquiries will normally be provided within a few days The papers of

authors who receive an invitation to submit their manuscripts will then enter the regular

editorial process

Submitted manuscripts will be assigned to one of the Brazilian Journal of Medical and

Biological Research Section Editors who will promptly evaluate the paper and decide if it

is likely to meet the requirement of providing a major advance in its relevant field and

29

describing a sufficient body of work to support the main claims and if so it will be sent

out for peer review A Section Editor works with the Editor throughout the review process

Expert reviewers will be asked to assess the technical and scientific merits of the work

Once all reviews have been received and considered by the Editor and Section Editor a

decision letter to the author will be drafted

There are several types of decisions possible

bull accept the paper as submitted

bull accept it with revision

bull invite the authors to revise the manuscript prior to the final decision

bull reject the paper but with encouragement to resubmit it after extensive revision If

the authors submit another revised version it must be done as a new submission

(httpsubmissionscielobrindexphpbjmbrlogin)

bull or reject the manuscript outright typically because it does not meet the criteria

outlined above of originality importance to the field cross-discipline interest or sound

methodology

Upon acceptance the manuscript enters our production system Articles are typically

published online within 9 weeks of formal acceptance and usually before they are

assembled into a complete issue Publication may be further expedited when justified For

complete explanation see Editorial Review Polices

Preparation of Research Manuscripts

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

Supported file types

The following file formats can be accepted Detailed information for each file type can be

found by clicking on individual links

bull EPS (suitable for diagrams andor images)

bull PDF (suitable for diagrams andor images)

bull Microsoft Word (suitable for diagrams andor images figures must be a single page)

bull All abbreviations must be defined in this footnote even if they are explained in the

text

bull Tables must be understandable without referring to the text

bull Each table should be on a separate page after the Reference section in the submitted

manuscript Tables occupying more than one printed page should be avoided if possible

bull Vertical and diagonal lines should not be used in tables instead indentation and

vertical or horizontal space should be used to group data

bull AdaptingReproducing Tables and Relevant Permissions Acknowledgments of

original sources of copied material should be given as a reference in the table footnote

bull Tables must be cell-based do not use picture elements text boxes tabs or returns

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

followed by et al Title Journal (abbreviation) Year Volume Complete Pages

sufficient hard data to be appreciated by the reader The Brazilian Journal publishes

unstructured abstracts

The abstract should briefly and clearly present the problem experimental approach new

results as quantitative data if possible and conclusions It should mention the techniques

used without going into methodological detail and mention the most important results

Abbreviations should be kept to a minimum and should be defined in both the Abstract and

text

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

followed by et al Title Journal (abbreviation) Year Volume Complete Pages

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

Abstract

Since abstracts are published separately by Information Services they should contain

sufficient hard data to be appreciated by the reader The Brazilian Journal publishes

unstructured abstracts

The abstract should briefly and clearly present the problem experimental approach new

results as quantitative data if possible and conclusions It should mention the techniques

used without going into methodological detail and mention the most important results

Abbreviations should be kept to a minimum and should be defined in both the Abstract and

text

38

Please do not include any reference citations in the abstract If the use of a reference is

unavoidable the full citation should be given within the abstract

The abstract should not exceed 250 words and should be written as a single paragraph

double-spaced on a separate page following the title page

writing a good abstract

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

followed by et al Title Journal (abbreviation) Year Volume Complete Pages

(Abstract)

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

Supported file types

The following file formats can be accepted Detailed information for each file type can be

found by clicking on individual links

bull All explanatory information should be given in a footnote below the table

Footnotes should be used to explain abbreviations and provide statistical information

bull All abbreviations must be defined in this footnote even if they are explained in the

text

bull Tables must be understandable without referring to the text

bull Each table should be on a separate page after the Reference section in the submitted

manuscript Tables occupying more than one printed page should be avoided if possible

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

Since abstracts are published separately by Information Services they should contain

sufficient hard data to be appreciated by the reader The Brazilian Journal publishes

unstructured abstracts

The abstract should briefly and clearly present the problem experimental approach new

results as quantitative data if possible and conclusions It should mention the techniques

used without going into methodological detail and mention the most important results

Abbreviations should be kept to a minimum and should be defined in both the Abstract and

text

Please see lthttpwwwbjournalcombrwriting_a_good_abstracthtmlgt for suggestions on

writing a good abstract

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

followed by et al Title Journal (abbreviation) Year Volume Complete Pages

The Brazilian Journal of Medical and Biological Research follows the reference format of

the Uniform Requirements for Manuscripts Submitted to Biomedical Journals which can

be found on the website of the National Library of Medicine

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

followed by et al Title Journal (abbreviation) Year Volume Complete Pages

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

Acknowledgment of research grants and fellowships (agency and grant number)

Key Words

A list of key words or indexing terms (no more than 6) should be included A capital letter

should be used for the first letter of each key word separated by a semicolon The Journal

recommends the use of medical subject headings of Index Medicus for key words to avoid

the use of several synonyms as entry terms in the index for different papers on the same

subject Remember key words are used by the Scielo Database (see

httpwwwscielobrbjmbrarticles searchsubject) to index the article

Running title

This short title to be used as a page heading should not exceed 60 letters and spaces

Abstract

Since abstracts are published separately by Information Services they should contain

sufficient hard data to be appreciated by the reader The Brazilian Journal publishes

unstructured abstracts

The abstract should briefly and clearly present the problem experimental approach new

results as quantitative data if possible and conclusions It should mention the techniques

used without going into methodological detail and mention the most important results

Abbreviations should be kept to a minimum and should be defined in both the Abstract and

text

38

Please do not include any reference citations in the abstract If the use of a reference is

unavoidable the full citation should be given within the abstract

The abstract should not exceed 250 words and should be written as a single paragraph

double-spaced on a separate page following the title page

Please see lthttpwwwbjournalcombrwriting_a_good_abstracthtmlgt for suggestions on

writing a good abstract

Introduction

The Introduction should put the focus of the manuscript into a broader context As you

compose the introduction think of readers who are not experts in this field Include a brief

review of the key literature This should state the purpose of the investigation and

justification for undertaking the research and relationship to other work in the field An

extensive listing or review of the literature should not be used If there are relevant

controversies or disagreements in the field they should be mentioned so that a non-expert

reader can delve into these issues further The Introduction should conclude with a brief

statement of the overall aim of the experiments and a comment about what was achieved

Material and Methods

Sufficient information should be provided in the text or by referring to papers in generally

available journals to permit the work to be repeated

This section should provide enough detail for reproduction of the findings Protocols for

new methods should be included but well-established protocols may simply be referenced

We encourage authors to submit as separate files detailed protocols for newer or less well-

established methods These will be linked to the article and will be fully accessable

Results

39

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

followed by et al Title Journal (abbreviation) Year Volume Complete Pages

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

The results should be presented clearly and concisely Tables and figures should be used

only when necessary for effective comprehension of the data In some situations it may be

desirable to combine Results and Discussion into a single section The Results section

should provide results of all of the experiments that are required to support the conclusions

of the paper There is no specific word limit for this section but a description of

experiments that are peripheral to the main message of the article and that detract from the

focus of the article should not be included The section may be divided into subsections

each with a concise subheading Large datasets including raw data should be submitted as

supplemental files these are published online alongside the accepted article The Results

section should be written in past tense

Discussion

The purpose of the Discussion is to interpret the results and relate them to existing

knowledge Information given elsewhere in the text especially in Results may be cited but

all results not repeated in detail in the Discussion The Discussion should spell out the

major conclusions and interpretations of the work including some explanation of the

significance of these conclusions How do the conclusions affect the existing assumptions

and models in the field How can future research build on these observations What are the

key experiments that must be done The Discussion should be concise and tightly argued

If warranted the Results and Discussion may be combined into one section

Acknowledgments

When appropriate briefly acknowledge technical assistance advice and contributions from

colleagues People who contributed to the work but do not fit the criteria for authors should

be listed in the Acknowledgments along with their contributions Donations of animals

cells or reagents should also be acknowledged You must also ensure that anyone named in

40

the Acknowledgments agrees to being so named Financial support for the research and

fellowships should be acknowledged on the title page

References

Only published or accepted manuscripts should be included in the reference list Meeting

abstracts conference talks or papers that have been submitted but not yet accepted should

not be cited Limited citation of unpublished work should be included in the body of the

text only All personal communications should be supported by a letter from the relevant

authors Authors are responsible for the accuracy and completeness of their references and

for correct text citation When possible references which are easily available in English

should be cited

The BJMBR uses the numbered citation (citation-sequence) method References are listed

and numbered in the order that they appear in the text In the text citations should be

indicated by the reference number in parentheses Multiple citations within a single set of

parentheses should be separated by commas without a space (157) Where there are more

than three sequential citations they should be given as a range Example has been

shown previously (4ndash9) Make sure the parts of the manuscript are in the correct order

before nambering the citations

Because all references will be linked electronically as much as possible to the papers they

cite proper formatting of the references is crucial For all references list the first 6 authors

followed by et al Title Journal (abbreviation) Year Volume Complete Pages

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

Supported file types

The following file formats can be accepted Detailed information for each file type can be

found by clicking on individual links

Competing Interest

Authors are asked at submission to state whether they have any financial personal or

professional interests that could be construed to have influenced their paper Reviewers are

45

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files

conform to our Guidelines for Figure Preparation when preparing your figures for

production

Preparing figure files for submission

47

Brazilian Journal of Medical and Biological Research encourages authors to use figures

where this will increase the clarity of an article The use of colour figures in articles is free

of charge The following guidelines must be observed when preparing figures Failure to do

so is likely to delay acceptance and publication of the article

bull Illustrations for publication should be provided as separate files

bull Each figure of a manuscript should be submitted as a single file

bull Tables should NOT be submitted as figures but should be included in the main

manuscript file

bull Figures should be numbered in the order they are first mentioned in the text and

uploaded in this order

bull Figure titles and legends should be provided in the main manuscript not in the

graphic file

bull The aim of the figure legend should be to describe the key messages of the figure

but the figure should also be discussed in the text An enlarged version of the figure and its

full legend will often be viewed in a separate window online and it should be possible for a

reader to understand the figure without moving back and forth between this window and the

relevant parts of the text Each legend should have a concise title of no more than 15 words

The legend itself should be succinct while still explaining all symbols and abbreviations

Avoid lengthy descriptions of methods

bull Each figure should be closely cropped to minimize the amount of white space

surrounding the illustration Cropping figures improves accuracy when placing the figure in

combination with other elements when the accepted manuscript is prepared for publication

on our site For more information on individual figure file formats

48

bull Individual figure files should not exceed 5 MB If a suitable format is chosen this

file size is adequate for extremely high quality figures

bull Please note that it is the responsibility of the author(s) to obtain permission from the

copyright holder to reproduce figures (or tables) that have previously been published

elsewhere In order for all figures to be open-access authors must have permission from the

rights holder if they wish to include images that have been published elsewhere in non-

open-access journals Permission should be indicated in the figure legend and the original

source included in the reference list

Supported file types

The following file formats can be accepted Detailed information for each file type can be

bull All abbreviations must be defined in this footnote even if they are explained in the

text

bull Tables must be understandable without referring to the text

bull Each table should be on a separate page after the Reference section in the submitted

manuscript Tables occupying more than one printed page should be avoided if possible

bull Vertical and diagonal lines should not be used in tables instead indentation and

vertical or horizontal space should be used to group data

also asked to declare any interests that might interfere with their objective assessment of a

manuscript Any relevant competing interests of authors must be available to editors and

reviewers during the review process and will be stated in published articles

Abbreviations

Abbreviations should be kept to a minimum Define all abbreviations upon first use in the

text Non-standard abbreviations should not be used unless they appear at least three times

in the text

bull Explain all abbreviations in the text figure and table legends when they first appear

Keep the number of abbreviations to a minimum

bull Do not explain abbreviations for units of measurement [3 mL not 3 milliliters

(mL)] or standard scientific symbols [Na not sodium (Na)]

bull Abbreviate long names of chemical substances and terms for therapeutic

combinations Abbreviate names of tests and procedures that are better known by their

abbreviations than by the full name (VDRL test SMA-12)

bull Use abbreviations in figures and tables to save space but they must be defined in

the legend

Nomenclature

The use of standardized nomenclature in all fields of science and medicine is an essential

step toward the integration and linking of scientific information reported in published

literature We will enforce the use of correct and established nomenclature wherever

possible

46

We strongly encourage the use of SI units If you do not use these exclusively please

provide the SI value in parentheses after each value Examples

bull s for second

bull min for minute

bull h for hour

bull L for liter

bull m for meter

bull kDa for mass in kilodaltons

bull 5 mM rather than 5 x 10-3 M or 0005 M

Species names should be italicized (eg Homo sapiens)

Genes mutations genotypes and alleles should be indicated in italics Use the

recommended name by consulting the appropriate genetic nomenclature database eg

HUGO for human genes It is sometimes advisable to indicate the synonyms for the gene

the first time it appears in the text

The Recommended International Non-Proprietary Name (rINN) of drugs should be

provided

Figures

Figures must be submitted in high-resolution version (600 dpi) Please ensure that the files
