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

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

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

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

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

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

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

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

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

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

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-
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

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

) 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

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

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

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

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

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

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

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
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

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

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

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

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

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

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

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

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

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

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

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

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

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-
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

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

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

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

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

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

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
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

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

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

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

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
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

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

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

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

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

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

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

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

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

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

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

(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 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

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

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

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

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

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

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

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

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

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

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
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

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-

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

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

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

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

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

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

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

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

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
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 PowerPoint (suitable for diagrams andor images figures must be a single page)
bull TIFF (suitable for images)
bull JPEG (suitable for photographic images less suitable for graphical images)
bull BMP (suitable for images)
Tables
bull Tables must be submitted in word (doc) or Excel (xls)
bull Tables must be numbered consecutively with Arabic numerals in the text
49
bull Tables must have a concise and descriptive title
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
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

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

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

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

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
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

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 PowerPoint (suitable for diagrams andor images figures must be a single page)
bull TIFF (suitable for images)
bull JPEG (suitable for photographic images less suitable for graphical images)
bull BMP (suitable for images)
Tables
bull Tables must be submitted in word (doc) or Excel (xls)
bull Tables must be numbered consecutively with Arabic numerals in the text
49
bull Tables must have a concise and descriptive title
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
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

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

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

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

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 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

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

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

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

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

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
found by clicking on individual links

bull TIFF (suitable for images)
bull JPEG (suitable for photographic images less suitable for graphical images)
bull BMP (suitable for images)
Tables
bull Tables must be submitted in word (doc) or Excel (xls)
bull Tables must be numbered consecutively with Arabic numerals in the text
49

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
