摘 要: 采用双能X线骨密度仪(DXA)全身扫描测试的方法,对长期柔道专项训练的青年男子运动员19名(柔道组)和21名无正规的运动训练史的同龄男大学生(对照组)的骨密度(BMD)及某些身体指标进行对比分析,结果显示,柔道组和对照组骨密度、瘦体重和体脂百分率存在着显著性的差异(P<0.01);同时,柔道组BMD与身高、体重、瘦体重及体脂百分率具有较高的相关性。结果提示,身高、体重、瘦体重及体脂百分率等可影响骨密度值的大小,运动能提高全身骨密度。 Using the Dual energy X-ray absorptiometry(DXA) to carry on the testing , contrast analysis of BMD and some body modality target of youth man Judo athlete 19 people(Judo group)in the long-term special training, the same aged male university student (control group)in no regular sport training history. The result show that Judo group and control group has the significance difference of BMD, lean mass and the body fat percentage(P〈0.01), the Judo athlete BMD and the body weight, lean mass and the body fat percentage have the obvious correlation. The conclusion could be obtained that the indices of height, weight, lean mass and the body fat percentage and others can influence BMD and exercises can increase the BMD,
