Resumo

O envelhecimento está associado a perdas progressivas de força e massa muscular, que comprometem a funcionalidade e a qualidade de vida dos idosos. O treinamento resistido com cargas elevadas é eficaz para atenuar esses efeitos, porém nem sempre viável devido a limitações clínicas. Nesse contexto, a restrição de fluxo sanguíneo (RFS) aplicada ao exercício de baixa intensidade surge como alternativa promissora. Esta revisão de literatura teve como objetivo analisar os efeitos da RFS sobre variáveis musculares, funcionais e hemodinâmicas em idosos. A busca foi realizada nas bases PubMed, Web of Science e Google Acadêmico, entre janeiro e maio de 2025, utilizando descritores em português, inglês e espanhol, com filtros para publicações entre 2015 e 2025, em humanos e texto completo disponível. Foram incluídos 12 estudos, sendo a maioria ensaios clínicos randomizados, além de um quase-experimental. Os resultados indicaram que 9 estudos relataram aumentos de força muscular, 7 aumentos de massa muscular, 5 melhorias funcionais e 4 evidenciaram segurança hemodinâmica, reforçando a eficácia e a tolerabilidade da técnica. Conclui-se que a RFS representa uma alternativa segura e eficaz ao treinamento resistido tradicional, com potencial de aplicação em academias, clínicas de reabilitação e programas de saúde pública para promoção do envelhecimento ativo.
