영문 초록

  The purpose of this study is to investigate the effects of long-term weight and aerobic exercise on the change of bone mineral density, leptin and isokinetic muscle strength in older women. The subjects were 21 women who were divided into control, aerobic and weight exercise group. They are mean aged 40 years. Aerobic exercise program consist of aerobics at 55~80% of HRmax for 65min a day and 5 days a week, and weight exercise program consist of resistance training at 40~75% of one repetition maximum(1RM) for 50min a day and 5 days a week for 24 weeks respectively. All subjects were evaluated plasma leptin, and Cybex isokinetic muscle strength, and bone mineral density for control and experimental groups. The results of this study are followings, Body fat and plasma leptin level were significantly reduced liter 24 weeks in two exercise groups(p＜0,05, p＜0.01). A significantly increased radius and tibia bone mineral density was shown in the aerobic and weight exercise groups compared with the control(p＜0,05, p＜0.01). Isokinetic muscle strength were significantly increased in weight exercise group(p＜0.01) than other groups. Therefore we can conclude that for 24 weeks regular weight and aerobic exercise prevent obesity, osteoporosis in older women which is caused by leptin horm one and bone mineral density.
