Abstract
Background: This study explored the relationship between handgrip strength (HGS) and pulmonary function, respiratory muscle strength, and cardiopulmonary endurance in older adults. Methods: We recruited 128 community-dwelling older adults. Correlations between HGS, pulmonary function parameters, respiratory muscle strength, and cardiopulmonary endurance were analyzed. Results: Forced vital capacity (r = 0.180, P < .05), maximum voluntary ventilation (r = 0.180, P < .05), and 2-minute step test (r = 0.204, P < .05) were weakly correlated with HGS. Maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) had moderate correlations with HGS (r = 0.431 for MIP, 0.492 for MEP, P < .001). Conclusion: HGS was correlated with pulmonary function, respiratory muscle strength, and cardiorespiratory endurance.
