!
Os resultados do presente estudo indicam que não existe diferença nas respostas termorregulatórias, metabólicas e perceptivas entre exercícios de intensidade fixa e autorregulada. Assim, parece que o mecanismo de fadiga é independente do modo de realização do exercício.

TÍTULO DO PROJETO DE PESQUISA:
Efeitos do exercício de intensidade fixa, autorregulada e da temperatura ambiente nas respostas metabólicas, termorregulatórias e perceptivas durante 30km de ciclismo
Convidamos você para ser voluntário do projeto de pesquisa intitulado “Efeitos
do exercício de intensidade fixa, autorregulada e da temperatura ambiente nas respostas metabólicas, termorregulatórias e perceptivas durante 30km de ciclismo”. Este documento fornece informações sobre os experimentos, além de
informações sobre riscos e benefícios. Nele, seus direitos como participante de um estudo experimental são detalhados. Por favor, leia este documento completamente e pergunte sobre qualquer dúvida relacionada à sua participação no estudo.
O objetivo deste estudo é comparar as Efeitos do exercício de intensidade fixa, autorregulada e da temperatura ambiente nas respostas metabólicas, termorregulatórias e perceptivas durante 30km de ciclismo.
Você passará, em dias diferentes, por uma sessão de familiarização com o protocolo de exercício físico desta pesquisa e por quatro situações experimentais. Na sessão de familiarização, você fará o mesmo protocolo de exercício a ser realizado na primeira situação experimental: pedalar 30km na maior velocidade possível em sua própria bicicleta que será acoplada sobre um sistema de frenagem eletromagnética. Essa sessão de familiarização será realizada em uma temperatura ambiente de 24ºC.
As outras quatro situações experimentais serão as seguintes: pedalar 30 km na maior velocidade possível ou em uma intensidade pré-estabelecida (que será estipulada pelo pesquisador) em um câmara ambiental a uma temperatura ambiente de 35ºC e 24ºC. Duas situações experimentais (30km intensidade fixa e autorregulada) serão realizadas em temperatura ambiente de 35 ºC e outras duas situações experimentais (30km intensidade fixa e autorregulada) ocorrerão em temperatura ambiente de 24ºC. Essas temperaturas ambientais serão controladas por uma câmara ambiental.
Nos dias experimentais você chegará ao Laboratório de Fisiologia do Exercício (LAFISE) da Escola de Educação Física, Fisioterapia e Terapia Ocupacional da UFMG e será encaminhado para o vestiário para a colocação do sensor de temperatura retal e da roupa adequada e padronizada para o teste (short de ciclismo, meias e sapatilhas). O sensor de temperatura retal é feito de um material flexível, possui 3,5 mm de diâmetro e deverá ser inserido a cerca de 10 cm do esfíncter anal - distância que virá marcada na sonda. As sondas retais que serão utilizadas nos experimentos serão descartáveis. Para o registro da temperatura, a sonda é conectada a um teletermômetro. Antes do exercício físico, será entregue para você um recipiente descartável no qual você deve urinar. Será utilizada uma gota de urina para a medida da densidade da sua urina, o que permitirá a nós verificarmos o seu estado de hidratação. Caso você não esteja hidratado, lhe será

ambiental, onde serão realizados os experimentos. Durante o exercício serão medidas as seguintes variáveis: temperatura retal, temperatura timpânica (com um termômetro digital), temperatura da pele no peito, braço, coxa e perna (com um termômetro digital), a frequência cardíaca, velocidade e a cadência de pedalada, sudorese total, conforto térmico e a sua percepção subjetiva do esforço. Após o término do teste será feita a medida da massa corporal. Além disso, a cada 5 km de exercício e nos minutos, serão coletadas amostras de sangue (30µL) do lobo da orelha com o uso de capilares.
Todos os seus dados pessoais serão confidenciais, sua identidade não será revelada publicamente em hipótese alguma e somente os pesquisadores envolvidos neste estudo terão acesso a essas informações.
Não está prevista qualquer forma de remuneração para os voluntários. Todas as despesas especificamente relacionadas ao estudo são de responsabilidade do LAFISE.
Serão poucos ou nenhum os possíveis benefícios individuais decorrentes de sua participação no estudo. Apesar disto, espera-se que o estudo aumente as informações disponíveis sobre as respostas metabólicas e termorregulatórias a diferentes protocolos
