폐경여성들의 규칙적인 운동습관과 신체구성 및 골밀도의 상관관계

다국어 초록 (Multilingual Abstract)

The purpose of this study was to find the effects of exercises done by Postmenopausal Women (n=20) to their body composition, femur and lumbar of BMD. The subjects were females (between ages of 46 to 55) who don`t bone disease, endocrine disease, didn`t take Calcium, vitamin D supplements or steroids, and don`t exercise. The subjects have enrolled in aerobic exercise program with weight-bearing for 10 weeks. The subjects` heights and weights are measured by the measuring instrument (FA-94H), Fanics, Korea). Inbody 3.0(Biospace Co, Seoul, Korea) is measure body composition. With results from above measurements, body mass index(BMI) is obtained. Using Dual energy X-ray Absorptionmetry, DEXA: Hologic QDR-4500 is used for BMD, femoral neck, total BMD. Lunbar spine measurement, L1-L4 lumber is used. Then average and standard deviation of body composition were calculated. Finally, the effects of exercise on age, height, weight, %Body fat(%BF), WHR, BMI, femur and lumbar spine BMD were studied, and the their correlation was analyzed. Changes of body composition showed that %body fat, WHR, BMR, were significant different in before exercise than after exercise (p<.05). Changes of BMD showed that not significant difference. but Mean and SD of remur neck and total BMD have a increasing tendency. Also, %Body fat(p<.01), BMI(P<.0.5), and WHR(P<..01) were significant correlations with regular exercise. therefore physical activity affecting that Body weight, %Body fat, and BMI were decreased. And regular exercise affecting BMD of lumbar and femur. but not significant correlated The results shows that regular exercise did not have much effect on increasing bone mineral density level, but it is an effective way to maintain BMD. Therefore I think that regular exercise program should composed of accurate exercise intensity and durations.
