Resumen
The authors compared the effects of bodyweight resistance training at moderate- or high-speed conditions on muscle power, velocity of movement, and functional performance in older females. In a randomized, single-blinded noncontrolled trial, participants completed 12 weeks (three sessions/week) of bodyweight resistance training at high (n = 14; age = 70.6 +/- 4.3 years) or moderate (n = 12; age = 72.8 +/- 4.2 years) speeds. Data were analyzed with an analysis of variance (Group x Time) with alpha level set at <.05. After the intervention, timed up and go test performance (p <.05) and the rising from a chair test mean (22.4%) and maximal velocity (28.5%), mean (24.4%) and maximal power (27.7%), normalized mean (25.1%), and normalized maximal power (28.5%) increased in the high-speed group (p <.05). However, the moderate-speed group achieved no improvements (Delta 6.7-14.4%; p >.2). The authors conclude that high-speed bodyweight resistance training is an effective and economically practical strategy to improve the functional capacity of older women relevant to daily life activities.
