Effect of a moderate-intensity comprehensive exercise program on body composition, muscle strength, and physical performance in elderly females with sarcopenia

ObjectiveThis study aimed at examining an eight-week moderate-intensity comprehensive exercise training program on the parameters of sarcopenia in elderly females.MethodsA total 49 community-dwelling females with (65.5 ± 2.5) were assigned randomly to experiment group (EG, n = 25) and a control (CG, 24). In EG, was implemented, 1 h, 3 times per week, 24 sessions. The CG only received health public education two weeks, 4 times. Subsequently, differences between groups tested through two-way repeated ANOVA.ResultsASM, SMM, SMI EG significantly improved by 0.26 kg, 0.18 0.10 kg/m2, respectively. Group-by-time interactions different ASM [F (1,47) 6.25, η2 0.12] 6.77, 0.13]. Muscle strength 0.8 kg EG. Significant group-by-time interaction reported handgrip 6.8, 0.13] after intervention. Compared baseline, gait speed 0.05 m/s 5-time chair stand decreased 0.27 s (1, 47) 6.35, 0.12].ConclusionsThe confirmed as safe convenient program. Although load intensity is not sufficient improve speed, this protocol promising delaying overall results contributes improvement muscle mass, strength, 5TCS.
