目的：观察女子柔道、举重和跆拳道专业运动员年训练周期中骨密度及相关指标的变化规律。方法：40名女子柔道、举重和跆拳道运动员作为研究对象,平均年龄18.4±3.2岁。结合运动员一个年度训练周期,分别在训练周期的开始、中间和结束时检测BMD、HPO轴相关激素以及骨代谢生化标志物（BGP、BAP和TRACP-5b）的变化。结果：女子举重运动员在训练周期中,髋骨BMD的3次检测结果均显著高于女子柔道和跆拳道运动员的检测结果（P〈0.05）;女运动员雌二醇和T/C在3次检测中呈逐渐增加的变化趋势,而血清孕酮水平则逐渐降低;女运动员训练期间TRACP-5b呈现逐渐增加的变化特征,并显著高于训练周期的开始测定值（P〈0.05）。结论：女子柔道、举重和跆拳道运动员在年训练周期中髋骨BMD无显著变化,女子举重运动员髋骨BMD明显高于柔道及跆拳道运动员;血清雌二醇和T/C在年训练周期中逐渐增加,而孕酮逐渐降低,骨代谢生化标志物TRACP-5b明显增加。

Objects：In order to investigate the changing regularity of bone mineral density and indices concerned in professional female judo,weight lifting and taekwondo athletes during a year-training cycle.Methods：40 female judo,weight lifting and taekwondo professional athletes,aged 18.4±3.2 years,were recruited in this study.BMD,hormones of HPO axis and biochemical indices of bone metabolism（BGP,BAP,TRACP-5b）were detected at the beginning（test 1）,in the middle（test 2）and at the end of a 1-year routine training（test 3）cycle.Results：The pelvis BMDs of female weight lifting ath-letes in the 3 tests during the routine training cycle were all significantly higher than that of judo and taekwondo athletes（P0.05）.T/C and E2 tended to increase in the female athletes,but not for P.There was a tendency of increase of TRACP-5b in the female athletes during the training session,and a significant difference was found between the test 3 and the test 1（P0.05）.Conclusions：There was no significant change of pelvis BMD in female judo,weight lifting and taekwondo athletes during a year-training cycle.The pelvis BMD of female weight lifting athletes was significantly higher than that of other female athletes.The level of serum E2 and T/C increased gradually,but progesterone decreased,and biochemical markers of bone metabolism TRACP-5b increased significantly during the training cycle.
