目的:研究不同距离跑对青少年运动员和非运动员血清cTnT的变化,为青少年运动训练监控与运动健身提供实验依据。方法:选取中长跑青少年男运动员11名,同时选取与之年龄相对应的20名男性非运动员为受试对象,采用5km、10km、21km和42km跑,分别在跑前、跑后4h和跑后24h抽取静脉血,测定血清cTnT的含量,运动前和运动后受试者的晨脉。结果:5km、10km、21kTn和42km跑后4h,非运动员血清cTnT均显著高于运动员,只有42km跑后24h,非运动员显著高于运动员;10km、21km和42km跑后4h,运动员与非运动员血清姗均显著升高,而且运动距离越长,cTnT升高越明显,5km、10km和21km跑后24h,cTnT平均值恢复到心肌损伤界值以下,而跑42km的运动员组与非运动员组均未恢复到心肌损伤界值以下。5km、10km、21km和42km跑后4h(非运动员组因某些原因,有7名受试者未完成实验),运动员与非运动员血清cTnT超过心肌损伤界值的人数及比例为0(0)vs2(15.4%),3(27.3%)VS6(46.2%),7(63.6%)vs13(100%)和11(100%)VS13(100%);超过急性心肌梗塞界值的人数及比例为0(0)vs0(0),0(O)vs0(O),5(45.5%)vs11(84.6%),8(72,7%)vs13(100%)。21km跑后24h,运动员1人(9.1%),非运动员3人(23.1%)血清cTnT依然高于心肌损伤临界值。42km跑后24h,运动员5人(45.5%),非运动员7人(53.8%),血清cTnT超过心肌损伤临界值;运动员1人(9.1%),非运动员3人(23.100),血清cTnT超过急性心肌梗塞临界值。结论:青少年cTnT的释放与运动距离有关,而且运动会引起非运动员青少年心肌释放更多的cTnT,提示长时间运动对青少年非运动员可能造成更严重的心肌损伤。
目的:研究不同距離跑對青少年運動員和非運動員血清cTnT的變化,為青少年運動訓練鑑控與運動健身提供實驗依據。方法:選取中長跑青少年男運動員11名,同時選取與之年齡相對應的20名男性非運動員為受試對象,採用5km、10km、21km和42km跑,分彆在跑前、跑後4h和跑後24h抽取靜脈血,測定血清cTnT的含量,運動前和運動後受試者的晨脈。結果:5km、10km、21kTn和42km跑後4h,非運動員血清cTnT均顯著高于運動員,隻有42km跑後24h,非運動員顯著高于運動員;10km、21km和42km跑後4h,運動員與非運動員血清姍均顯著升高,而且運動距離越長,cTnT升高越明顯,5km、10km和21km跑後24h,cTnT平均值恢複到心肌損傷界值以下,而跑42km的運動員組與非運動員組均未恢複到心肌損傷界值以下。5km、10km、21km和42km跑後4h(非運動員組因某些原因,有7名受試者未完成實驗),運動員與非運動員血清cTnT超過心肌損傷界值的人數及比例為0(0)vs2(15.4%),3(27.3%)VS6(46.2%),7(63.6%)vs13(100%)和11(100%)VS13(100%);超過急性心肌梗塞界值的人數及比例為0(0)vs0(0),0(O)vs0(O),5(45.5%)vs11(84.6%),8(72,7%)vs13(100%)。21km跑後24h,運動員1人(9.1%),非運動員3人(23.1%)血清cTnT依然高于心肌損傷臨界值。42km跑後24h,運動員5人(45.5%),非運動員7人(53.8%),血清cTnT超過心肌損傷臨界值;運動員1人(9.1%),非運動員3人(23.100),血清cTnT超過急性心肌梗塞臨界值。結論:青少年cTnT的釋放與運動距離有關,而且運動會引起非運動員青少年心肌釋放更多的cTnT,提示長時間運動對青少年非運動員可能造成更嚴重的心肌損傷。

Objective:To investigate the impact of different distance run on the change of serum cTnT in adolescent athletes and non-athletes in order to offer experimental evidence for youth sports training monitor and sports fitness. Methods: It analyzed the serum cTnT 5km, 10km, 21km and 42 km run before, after 4 and 24 hours and assayed the morning pulse before and after run in male adolescent athletes and non-athletes. Results : After 5 km, 10kin, 21 km and 42km run four hours, the serum cTnT level in non-athletes was higher than in athletes, however,only 42kin run after 24 hours, and cTnT was higher in non-athletes than in athletes. The serum cTnT level 10kin, 21km and 42kin run after 4 hours was increased in athletes and no-athletes and its increase accorded with the run distance. The level of serum cTnT recovered normal after 24 hours run in 5 km, 10 km, 21 km running but 42 km run didn't recover in athletes and non-athletes. The number and percent of over cardiac injury cutoff of serum cTnT in athletes and non-athletes were 0(0)vs 2 (15.4%),3(27.3%)vs 6(46.2%),7(63.6%) vs 13(100%) and 11(100%) vs 13(100%) and over acute cardiac infarction cutoff were 0(0) vs 0(0),0(0) vs 0(0),5(45. 5%) vs 11(84. 6%),and 8(72. 7%)vs 13(100%)after 4 hours of 5 km, 10 km, 2 lkm and 4 2 km run. Twenty one kilometers run after 2 4 hours , one in athletes and three in non-athletes serum eTnT level was still higher than cutoff of cardiac injury. Forty-two kilometers run after 24 hours, five in athletes and seven in non-athletes serum eTnT was still higher than cutoff of cardiac injury and the serum cTnT level of one in athlete and three in non-athletes wasn't decreased to the cutoff of acute cardiac infarction. Conclusion:The release of serum eTnT was associated with run distance and there was more cTnT released from cardiac muscle in adolescent non-athletes than in adolescent athletes. It indicated that long time exercise may cause serious cardiac injury in adolescent non-athletes.
