目的：分析青少年运动员急性运动后血清cTnT水平与身体机能状态的关系。方法：30名青少年男子运动员,年龄（16.1.1±0.5）岁,进行了一次尽全力的21 km跑,测定运动前后血清cTnT以及运动前血清睾酮、皮质醇、免疫球蛋白A、免疫球蛋白G、铁以及血红蛋白水平。分析这些机能指标与运动后血清cTnT释放的相关性。结果：运动前血清中未发现cTnT,运动后73%的运动员血清cTnT水平（中位数：0.11;范围：〈0.01～1.22 ng/mL）超过心肌损伤界值。运动后血清cTnT水平与运动前血清皮质醇（r=0.889,P〈0.001）,以及睾酮与皮质醇比值（r=-0.589,P〈0.001）呈显著相关,而与其他机能指标未呈现显著相关性。结论：机体分解代谢增强的青少年运动员倾向于有更高的运动后血液cTnT水平。

Objective： This study was to investigate relationship between post-exercise cTnT release and resting physical function state in adolescent runners.Methods： 21 km running was performed by 30 adolescent runners（age： 16.1±0.5 years） after abstaining from hard training within the 24h period.Their serum cTnT was determined by using the third-generation Roche cTnT assay before and after exercise.Moreover,serum testosterone,cortisol,IgA,LgG,Fe and blood hemoglobin were also assessed at rest before exercises.The paper analyzes the correlation between the physical indicators and the release of cTnT in serum after exercises.Results： cTnT was undetectable before exercises.Post-exercise serum cTnT（median,range： 0.11,0.01-1.22 ng/mL） was elevated.The post-exercise cTnT values were correlated to resting cortisol levels（r= 0.889,P0.001） and ratio of testosterone to cortisol（r=-0.589,P0.001）,but indices do not have significant correlation.Conclusion： The runners with greater catabolism levels,as indicated by lower serum ratio of testosterone to cortisol,induced a higher serum cTnT following endurance exercise.
