散打运动员身体骨密度(BMD)变化趋势分析

Analysis Of Change Trend Of Sanda Athlete's Bodily Bone Mineral Density(BMD)

通过文献资料、数理统计等研究方法对散打运动员7个部位的BMD进行测试,分析了运动员这些部位BMD的变化趋势。其结果是:男子散打运动员的上肢骨骼和下肢骨骼的BMD都是远端低,近端高,从肢体远端到近端的BMD变化成逐渐升高的趋势;女子散打运动员的上肢骨骼的BMD变化也成逐渐升高的趋势,但其下肢3个部位的骨骼BMD变化有所不同,从跖骨到胫腓骨是明显的升高,从胫腓骨到股骨却有略微下降。

This article through research techniques and literature material, mathematical statistic to disperses hits the athlete 7 spots BMD to test, has analyzed the athlete these spot BMD change tendency. The result showed that the man disperses hits athlete＇s upper limb skdeton and lower limb skeleton BMD all is the farend is low, the near- end is high, changes the tendency from the body farend to near- end BMD which elevates gradually; The female disperses hits the tendency which athlete＇s upper limb skeleton BMD change also becomes elevates gradually, but its lower limb 3 spot skeleton BMD changes differs from the shin fibula to the thighbone drops slightly.
