Single- and multiple-set resistance training improves skeletal and respiratory muscle strength in elderly women

Aging involves a progressive reduction of respiratory muscle strength as well as muscle strength. Compare the effects of resistance training volume on the maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), functional performance, and muscle strength in elderly women. Thirty elderly women were randomly assigned to a group performing either single sets (1-SET) or three sets (3-SET) of exercises. The sit-to-stand test, MIP, MEP, and muscle strength were assessed before and after 24 training sessions. Progressive resistance training was performed two times per week for a total of 8-12 repetitions, using the main muscle groups of the upper and lower limbs. The main results showed that the participants significantly increased their MEP (P
