Does exercise intensity increment in exergame promote changes in strength, functional capacity and perceptual parameters in pre-frail older women? A randomized controlled trial

The aim of this study was to compare the effects of two exercise intensities on exergame training program in muscle strength, functional capacity and perceptual parameters in pre-frail older women. Thirty-four women (69.5 ± 5.4 years) were randomly assigned to either moderate- (MG: 11–13 perceived exertion) or vigorous-exercise intensity group (VG: 14–16 perceived exertion). Muscle strength and functional capacity were evaluated before and after 3 months of training. The affective responses were measured once a week and perceived benefit was evaluated after training period. The MG improved the average power at 60°/s from pre- to post-training (p
