Effects of Aerobic, Resistance, Balance Exercise Program on Skeletal Muscle Index, Functional Fitness, and Health-Related Quality of Life in Frail Elderly Women.
[PURPOSE] The purpose of this study was to investigate the effects of aerobic, resistance, balance exercise program on skeletal muscle index, functional fitness, and health-related quality of life in frail elderly women. [METHODS] The subjects were com-prised of 18 frail elderly women(exercise group, n=9; control group, n=9). The exercise program performed the aerobic ex-ercise(20 minutes), resistance exercise(20 minutes), and balance exercise(10 minutes) a day, 3 days per week, for 12 weeks. The changes of body composition, fitness, health-related quality of life(SF-36) were measured and analyzed at pre- and post- ex-ercise program for verifying the exercise effectiveness. [RESULTS] In body composition body weight(p<.01), and % fat(p<.001) were significantly decreased, but skeletal muscle mass and skeletal muscle index were not changed. In functional fitness, VO2max(p<.01), grip strength(p<.001), arm curl(p<.001), chair sit to stand(p<.001), back scratch(p<.05), and chair sit & reach(p<.01) were significantly increased and timed up & go(p<.01) were significantly decreased. In SF-36, physical function-ing(p<.01), body pain(p<.001), general health(p<.001), role-emotional(p<.05), and mental health(p<.01) were significantly increased. [CONCLUSIONS] These findings suggest that combination of aerobic, resistance and balance exercise program showed the beneficial effects on functional fitness and SF-36 in frail elderly women.
