Objetivo. Verificar una correlación entre masa y función neuromuscular con la fuerza de mulheres practicantes y no practicantes de actividades físicas. Métodos. Trata-se de um estudo transversal realizado con mulheres idosas (60 anos ou mais), fisicamente ativas (FA) e fisicamente inativas (FI). Foram avaliadas as forças musculares do membro superior (força de preensão manual - FPM; teste RESISFOR) e do membro inferior (teste de pé de cadeira de 30 segundos); bem como a massa muscular (circunferência da panturrilha - CC); e atividade neuromuscular (sEMG) dos seguintes músculos: flexor radial del carpo (FCR) e bíceps braquial (BB) (membro superior); vasto lateral (VL), vasto medial (VM) y tibial anterior (TA) (membro inferior). O teste t de Student e una regresión lineal múltipla foram usados (95%; p <0,05). Resultados. No general, foram avaliadas 59 mulheres (71,5 ± 7,1 años), 31 FA e 28 FI. Mulheres FA tiveram valores significativamente melhores em testículos de fuerza muscular dinámica dos membros superiores (p = 0,001) e inferiores (p <0,0001). Não houve diferença significativa na massa muscular entre os grupos. Após o ajuste para covariáveis, houve relação entre CC e atividade do músculo FCR com FPM (R2adj. = 0,64), e CC com o teste de pé de cadeira de 30 segundos (R2adj. = 0,39) em mulheres com AF . Entre como mulheres FI, houve correlação significativa entre a atividade do músculo FCR e HGS (R2adj. = .35) e CC e atividade neural de FCR com RESISFOR (R2adj. = .66). Conclusão. O exercício físico foi relacionado a maior força muscular dinâmica. Diferenças na relação entre una massa muscular e una atividade neuromuscular com a força em cada teste indicam diferenças fisiológicas para cada ejercicio de força aplicado.
