Correlations between Muscle Mass, Muscle Strength, Physical Performance, and Muscle Fatigue Resistance in Community-Dwelling Elderly Subjects
Abstract: To determine the
correlations between muscle mass, muscle strength, physical performance, and
muscle fatigue resistance in community-dwelling 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.
