Abstract |
The purpose of this study was to examine the effects of combined exercise program on predictors of lumbar bone mineral density and bone metabolism of postmenopausal women and provide the basic data for the prevention of osteoporosis. The subjects of this study were postmenopausal women of 5357 years old and they did not have any experience to participate in planned exercise program during the recent 24 months. They were divided into a control group(n=13) and a combined exercise group(n=15). However, five subjects dropped out from the combined exercise group due to personal illness or non-participation in this exercise. Four subjects dropped out from the control group due to non-participation upon measuring and personal circumstances. In the combined exercise group, a combined exercise consisting of walking and resistance exercise for 12 weeks has been conducted. Each exercise capacity was evaluated every week and the exercise time, the exercise frequency and the exercise intensity were readjusted. The results showed that there was no significant difference of change in the weight of the body composition but BMI was significantly decreased in the combined exercise group compared to the control group(p<0.01). Lumbar BMD was significantly increased after the exercise in the combined exercise group compared to before the exercise(p<0.01). Tscore was significantly increased after the exercise in the combined exercise group compared to before the exercise(p<0.001). The changes of one metabolism indicators(osteocalcine, CTx and ALP) in blood were significantly decreased after the exercise in the combined exercise group compared to before the exercise(p<0.01). Taken all above results together, it is thought that regular combined exercise program gives a positive impact on bone mineral density and bone metabolism indicators of postmenopausal women. |
