하지근력강화 운동프로그램이 노인 여성의 등속성근력과 낙상예방 관련체력에 미치는 영향

The purpose of this study is to analyze the effect of lower body muscles strength exercise program on the isokinetic strength and fall prevention fitness of the elderly women. The subject recruited 16 elderly women aged 65 or older who could participate in physical activity and have no medical results. They were randomly assigned into the exercise group(n=8) and the control group(n=8). lower body muscles strength program were performed three times a week for 60 minutes and 8weeks. The measurement items were body composition (body weight, body fat, fat free mass), isokinetic strength, fitness factors related to fall prevention (Lower body muscle function, flexibility, dynamic equilibrium, coordination). The results are as follows. First, in the changes of body composition, there was no significant change in body weight and body fat percentage in the exercise group participating in the lower body muscles strength exercise program, and fat free mass and skeletal muscle amount were significantly increased. Second, in the change of isokinetic strength, the exercise group participating in the lower body muscles strength exercise program increased significantly in extension and flexion. Third, there was no significant change in flexibility among fitness factors related to fall prevention. Lower body muscle function, dynamic balance, and coordination were significantly increased, which showed a positive effect. Based on the above results, it was shown that the exercise program for the elderly women showed a positive change in isokinetic strength and physical fitness related to falls prevention in the elderly women.
