Effects of Weekly Set Volume on Muscle Adaptation

Brazil57 participantsStarted 2026-01-01

Plain-language summary

The progressive loss of strength and muscle mass is a natural aging process, with direct implications for functional capacity. Resistance training (RT) is considered the main intervention to counteract this decline. Although the RT guidelines are well established, the ideal weekly set volume to maximize strength and hypertrophy gains in older adults remains unknown. The purpose of this study is to investigate the effects of different volumes of weekly sets of RT on muscle strength and hypertrophy in older adults
