Abstract: BACKGROUND: Respiratory-muscle weakness is an important clinical problem. The respiratory system’s health is a decisive factor in the physical and social life of the elderly. Changes in respiratory muscular strength and function activate the torso’s adjustment ability, which affects daily activities. OBJECTIVE: This study aimed to investigate the effects of resistance exercises combined with breathing exercises on the respiratory-muscle strength of elderly women. METHOD: This study included 26 elderly woman, who were randomly divided into two sub-groups of 13 participants each. The experimental group performed breathing exercises and dynamic upper- and lower-extremity exercises, and the control group practiced only dynamic upper- and lower-extremity exercises. The maximum expiratory pressure (MEP) and maximum inspiratory pressure (MIP) were measured both before and at the end of the six-week study. RESULTS: In both groups, both the post-test MIPs and MEPs were significantly higher than the pre-intervention ones (p< 0.05). For MIPs, the between-group difference was not statistically significant, either before the intervention or post-test (p> 0.05). For MEPs, the between-group difference was statistically significant at post-intervention points (p< 0.05). CONCLUSION: The results showed that resistance exercises applying maximum expiration improved the respiratory-muscle strength of elderly women. These findings indicate that resistance exercises applying maximum expiration as described here in should be considered in patients who require breathing therapy, because the combination seems to significantly increase the strength of the respiratory muscles.
