MÉTODO
Trata-se de um estudo com delineamento experimental por aplicar tratamentos específicos em grupos de indivíduos, visando controlar a ação de fatores intervenientes e investigar graus de mudança em variáveis dependentes.
Amostra
A amostra foi constituída por 20 mulheres fisicamente inativas, com idades entre 19 e 34 anos (25.70 ± 4.20 anos), todas residentes na cidade de João Pessoa – PB, Brasil, que foram designadas aleatoriamente para os grupos experimental (GE, n = 10) e controle (GC, n = 10).
Como critério de inclusão amostral, ficou estabelecido que as voluntárias do estudo deveriam responder negativamente a todos os itens do questionário Physical Activity Readiness Questionnaire (PAR-Q) (Shephard, 1988) e se encontrar sem praticar atividade física regular por um período mínimo de seis meses (American College of Sports Medicine, 2009). Quanto aos critérios de exclusão, determinou-se que seriam retiradas do estudo aquelas que não apresentassem 85% de frequência ao programa de treinamento (Simão, Polito, & Monteiro, 2008).
De acordo com a Resolução 196/96 do Conselho Nacional de Saúde do Brasil, o estudo foi aprovado pelo Comitê de Ética em Pesquisa do Centro de Ciências da Saúde da Universidade Federal da Paraíba (UFPB) sob o protocolo n.º 204/09, e as participantes assinaram um termo de consentimento livre e esclarecido, o qual continha informações sobre tipo, objetivos e procedimentos a serem realizados ao longo do protocolo experimental do estudo.
