通过对 5名山西省男子柔道运动员冬训大负荷训练期血清睾酮 (T)、皮质醇 (C)的测试分析表明 ,大负荷训练使男子柔道运动员的T、T/C值显著下降 (P <0 .0 5 ) ,5名运动员不同程度地表现出运动疲劳 ,C值变化不明显 (P >0 .0 5 )。提示 :T、C、T/C是男子柔道运动员大负荷训练期机能评定的有效指标 ,对防止运动员过度疲劳、及早发现和预防运动员潜在性贫血具有较高的参考价值 The test results of serum testosterone (T) and cortisol (C) in five male Shanxi judo athletes during winter training large load training showed that the T, T / C values ​​of male judo athletes decreased significantly (P <0 .0 5), 5 athletes showed varying degrees of exercise fatigue, C values ​​did not change significantly (P> 0.05). It is suggested that T, C, T / C are effective indicators for men judo athletes’ performance during heavy-load training period and have a high reference value for preventing over-tired athletes and early detection and prevention of potential anemia among athletes
