RESUMO: A diminuição da força muscular com o envelhecimento e os baixos níveis de atividade física contribuem para défices funcionais e de equilíbrio. Esta revisão sistemática teve como objetivo analisar os estudos que correlacionaram o treino resistido (TR) isolado, o equilíbrio e a função de idosos saudáveis. A busca nas bases do Google Acadêmico e na BVS levou à seleção de 35 estudos controlados. O TR isolado mostrou ser relevante para a função dos idosos (90% dos estudos) devido sobretudo ao ganho de força e mobilidade. Exercícios de baixa e moderada intensidade tiveram melhores resultados sobre a função de idosas, frágeis e sedentários. Em relação ao equilíbrio, apesar da inconsistência dos dados, o TR parece exercer efeitos positivos, sobretudo devido a fatores neuromusculares. Estudos com parâmetros de treino e amostra uniformes são necessários para melhor comparação dos resultados, sobretudo em idosos com padrão funcional elevado.

The purpose of this systematic review was to assess the effects of resistance training (RT) alone on balance performance and functional capacity in healthy elderly. The search in Google Scholar and BVS led to selecting 35 controlled trials. The RT alone showed to have positive effects (90% of the studies) on functional tasks in elderly, associated with increases in strength and mobility. Moderate and low-intensity exercise could produce functional capacity benefits in older women, frail and sedentary elderly. Despite the inconsistency of data, resistance training appears to exert positive effects on balance, especially through neuromuscular factors. Standardization of methodology and homogeneity of sampling may ensure greater comparability of results, especially among elderly with high physical functional level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
