篮球专业和非篮球专业男性大学生身体不同部位骨密度对比分析

目的：观察长期从事篮球运动对身体不同部位骨密度(BMD)和骨代谢相关生化指标的影响。方法：选择训练年限在10年以上篮球运动员和非体育专业大学生同龄男性志愿者各15名，分别为训练组和非训练组;采用骨密度测定仪和血清放射免疫法测定受试者腰椎、左右髋关节的股骨颈、双侧髋关节、股骨Ward区、双侧前臂的BMD以及血清睾酮(T)、皮质醇（COR）、甲状旁腺素（PTH）、骨钙素(BGP)的变化。结果：训练组腰椎(L₂～L₄)、右前臂和髋关节股骨颈BMD峰值明显高于非训练组 (P<0.05或P<0.01)。静息状态下两组T、COR、PTH和BGP差异无显著性(P>0.05)。结论：长期从事篮球运动能有效地增加身体BMD，但安静状态下对T、COR、PTH和BGP无明显影响。

Comparison of bond mineral density at different parts between hoopman and non-hoopman in collelge

Objective To study the influences of long-term basketball training on bond mineral density(BMD)at different parts of hoopman in college.Methods Fifteen male basketball athletes (training for 10 years) from Institute of Physical Education were selected as training group,fifteen non-sports male college students(with the same age)were used as non-training group.The BMD of both left and right femur of different parts of femurs(neck and ward),the spine and the L2,L3,L4 of spine and both left and right forearm and the levels of serum testosterone(T),cortisone(COR),parathyroid hormone(PTH),and bone da protein(BGP) were determined by dual energy X-ray absorptiometry(DXA) of whole body and irradiation immunity of serum.Results The peak values of BMD of L2,L3,L4,right forearm,neck of left and right hip joint in training group were significantly higher than those in non-training group(P<0.01 or P<0.05).The levels of serum T,CDR,PTH and BGP at rest had no significant differences between two groups(P>0.05).Conclusion Long-time basketball training can effectively increase the BMD of L2,L3,L4 of spine,right forearm,left and right hip joint.But it has no effect on the serum T,COR,PTH,and BGP at rest.
