자발적 운동참여가 중년 여성들의 골밀도, 최대산소섭취량, 건강관련체력에 미치는 영향

초록

The purpose of this study is to find effects of regular exercise for bone mineral density(BMD), VO2max, Health related fitness in Korean Middle-aged women and to present basic data of an effective exercise program for the prevention and cure of osteoporosis. The subjects were 330 middle-aged women, who were divided into 130 in exercise group and 200 in non-exercise group, and then BMD of radius, lumbar and femur, body composition, VO2max and isokinetic muscle strength, health related fitness were measured. The results from t-test of each variable, analysis of correlation are the followings. 1) It was showed that BMD of lumbar, femur, weight and peak torque of right and left knee extension muscle and both flexion muscle in exercise group were significantly higher than those in non-exercise group. 2) There were statistically significant correlations among BMD of lumbar and peak torque of left and right extension muscle. There were statistically significant correlations among BMD of femur and weight, peak torque of right extension and flex muscle, and age 3) For non-exercise group, there were statistically significant correlations among age and BMD of radius, lumbar and femur. Regular exercise has positive effect not only on increase of BMD but also on increase of the amount of lean body mass, aerobic capacity and improvement of health related fitness. The exercise, in process of which continuous weight bearing can be given, is more effective, and especially in order to maintain and improve BMD of radius, lumbar and femur, which are more likely to result in a fracture of bone caused by osteoporosis, it is more effective to carry out muscle strength which can make continuous muscle contraction for parts concerned. The result of this study, I suggest that a succeeding study on practical exercise program is need for the prevention and cure of osteoporosis.
