我们调查了103名男性和女性志愿大学生运动员的骨代谢系统状况，他们积极从事三种不同的运动：长跑（LR）;柔道（JU）;和游泳（SW）。评价以下参数：全身骨矿物质密度（TMBD）;骨形成代谢标志物;血清I型前胶原C肽（PICP）水平;骨碱性磷酸酶（B-ALP）含量;骨吸收标志物，尿吡啶啉（Pyd）和脱氧吡啶啉（Dpd）水平。结果发现，JU组运动员TBMD和尿Dpd值显著高于其他两组同性别运动员（P < 0.001）。JU组男运动员尿Pyd水平显著高于其他两组（P < 0.001），而JU组女运动员尿Pyd水平仅显著高于LR组（P < 0.01）。所有组的PICP水平与TBMD值相似。在同一性别的LR和SW运动员中，骨密度或骨代谢标志物没有差异。因此，我们得出结论，骨矿物质密度的差异部分是由于特定运动的需求，它们反映在骨代谢标志物中。此外，训练期的JU男运动员可能处于高代谢状态，月经周期规律的JU女运动员也可能处于高代谢状态。
We investigated the bone metabolic system status of 103 male and female volunteer collegiate athletes, who were actively pursuing one of three different sports: Long-distance running (LR); judo (JU); and swimming (SW). The following parameters were evaluated: total body bone mineral density (TMBD); bone-forming metabolic markers; serum procollagen type I C-peptide (PICP) levels; bone alkaline phosphatase (B-ALP) content; bone resorption markers, urinary pyridinoline (Pyd) and deoxypyridinoline (Dpd) levels. We found that the TBMD and urinary Dpd values in JU athletes were significantly higher (p < 0.001) than in athletes of the same sex in the other two groups. The urinary Pyd level in male JU athletes was also higher (p < 0.001) than that in the other two groups, but that in females JU athletes was only higher (p < 0.01) than that in female LR athletes. The PICP levels were similar to the TBMD values in all groups. No differences in bone density or in bone metabolic markers were seen in LR and SW athletes of the same sex. We thus conclude that differences in bone mineral density are in part due to the demands of the specific sport, and that they are reflected in bone metabolic markers. In addition, the status of bone metabolic turnover in male JU athletes in training may be hypermetabolic and as well as that of female JU athletes with regular menses cycles.
