摘　　要：本文应用双光能源及单光能源骨密度测试,血清维生素D_3,雌二醇、胆固醇、碱性磷酸酶水平等,分别对竞技体校及普通小学两个年龄组,青春发育前后共63名学生进行测试,结果显示:运动训练有助于提高骨密度(单位面积中的骨矿含量Bone Mine-ral Density,简称BMD),长期控体重对青春发育前运动员骨密度未见影响,而发育后运动员,雌激素较低者,骨密度较低,赛前快速控体重运动员,骨密度仍高于同龄不训练者。To study the effects of exercise and weight control on bone mineral density (BMD) of girl athletes, dual X-ray and single X-ray absorptiometry were adopted to measure BMD; And serum Vitamin D3, estrogen, cholesterol and alkaline phosphatase levels of subjects were determined. Subjects were 63 students of two age groups (before puberty. 8-9 years old; after puberty: 15-16 years old, respectively) of sports and ordinary schools. The results showed that.. Exercise training is beneficial to increase BMD; Long term weight control had no effect on BMDof athletes in this study; Yet girl athletes after puberty with low estrogen levels had less BMD; Girl judo players with rapid weight loss had higher BMD as compared with the same aged nontraining students.
