Résumé
This study analyzed if the associations of physical activity with physical fitness and physical function in older women are mediated by muscle power. Participants were 54 older women (age 73.5 ± 6.8 yrs). Moderate-to-vigorous intensity physical activity (min day Mediation analysis controlling to age revealed an indirect effect of moderate-to-vigorous intensity physical activity through muscle power on all physical fitness components, specifically lower body strength (B = 0.048, 95% BootCI [0.013, 0.114]), agility/dynamic balance (B = -0.009, 95% BootCI [-0.024, -0.002]) and aerobic endurance (B = 0.656, 95% BootCI [0.142, 1.597]) and on physical function global score (B = 0.040 95% BootCI [0.009, 0.094]). These results suggest that physical activity of at least moderate intensity is relevant to daily functional competence, by promoting the maintenance or improvement of muscle power.
