Correlations between Muscle Mass, Muscle Strength, Physical Performance, and Muscle Fatigue Resistance in Community-Dwelling Elderly Subjects

Objective: To determine the correlations between muscle mass, muscle strength, physical performance, and muscle fatigue resistance in communitydwelling elderly people in order to elucidate factors which contribute to elderly’s performance of daily activities. Methods: A cross-sectional study was conducted on community-dwelling elderly in Bandung from September to December 2014. One hundred and thirty elderly, 60 years old or above, were evaluated using bioelectrical impedance analysis to measure muscle mass; grip strength to measure muscle strength and muscle fatigue resistance; habitual gait speed to measure physical performance; and Global Physical Activity Questionnaire (GPAQ) to assess physical activity. Results: There were significant positive correlations between muscle mass (r=0,27, p=0,0019), muscle strength (r=0,26, p=0,0024), and physical performance (r=0,32, p=0,0002) with muscle fatigue resistance. Physical performance has the highest correlation based on multiple regression test (p=0,0025). In association with muscle mass, the physical activity showed a significant positive correlation (r=0,42, p=0,0000). Sarcopenia was identified in 19 (14.61%) of 130 subjects. Conclusions: It is suggested that muscle mass, muscle strength, and physical performance influence muscle fatigue resistance.
