Fifty-six women will be randomly assigned to one of two muscle power training supervised for a physical activity instructor with different velocity loss (VL) thresholds: 10% (VL10) and 30% (VL30). Subjects followed a muscle power training for 8 weeks (2 sessions per week on alternate days) using the leg extension exercise, with similar relative intensity (50% 1RM). Between weeks one and four two series will be performed per session. Then the number of series will increase to three per session. The inter-set recovery period will be always of 2-min. Before and after the muscle power training the following tests will be performed: 1) measure of body composition with dual-energy x-ray absorptiometry for determining the lean mass of thighs; 2) three functional test (chair stand test, time up go test with cognitive task and gait speed test); 3)Progressive loading test in a leg extension machine until finding the mean muscle power corresponding to 50% of 1RM (speed of concentric phase of 6.67 ± 0.04 m/s measured using a camera-based optoelectronic system).
