Introduction: The neuromuscular and respiratory systems are significantly affected during the sedentary aging, but these modifications can be minimized/attenuated by practice of resistance training Purpose: Compare the effects of different volumes of resistance training on the maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), functional performance, and muscle strength in elderly women. Methods: Nineteen 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. Results: The main results showed that the participants significantly increased their MEP (p<0,05; 1-SET: 34,6%; 3-SET: 35,8%) and MIP (p<0,05; 1-SET: 13,7%; 3- SET: 11,2%). Both groups also improved in the sit-to-stand test (p<0,05; 1-SET: 10,6%; 3-SET: 17,1%). After 24 training sessions, muscle strength also significantly increased (p<0,0001; 40 80%) in both groups. An intergroup comparison did not show any statistically significant differences between the groups in any of the parameters analyzed. Conclusion: Single- and multiple-set resistance training programs increased MIP, MEP, muscle strength, and sit-to-stand test performance in elderly women after 24 sessions of training. In conclusion, our results suggested that elderly women who are not in the habit of physical activity may start with single-set resistance training programs as a short-term strategy for the maintenance of health.
