The purpose of this study was to investigate effects of group exercise training on skeletal muscle mass, glucose, blood pressure, vital capacity, and functional performance of lower extremity in frail elderly. 35 subjects (3 males, 32 females) were participated in this study. Exercise program consisted of breathing, strengthening, postural correction, and aerobic training was applied for 55-minutes/day, 1 day/week, 12 weeks. Design of this study was pre and post test. We measured body fat percentage, skeletal muscle mass, glucose level, systolic blood pressure, and forced vital capacity for body function. Sit to stand test and timed up and go test were performed for functional performance of lower extremity. There were significant differences in the skeletal muscle mass, glucose level, systolic blood pressure, forced vital capacity, numbers of sit to stand, and timed up and go test (p<.05). Thus it is suggested that group exercise program including breathing and aerobic training may paly a significant role in improving pulmonary function and functional performance of lower extremity in frail elderly.
