【摘要】：目的:探讨柔道运动员冬训期一次技术实战训练课后超敏肌钙蛋白I(hs-c Tn I)的变化,为柔道运动员训练期间心脏机能的监控提供方法和手段。方法:以12名优秀柔道运动员(男女各半)和12名普通柔道运动员(男女各半)为研究对象,进行冬训期的一次技术实战课,对所有运动员进行全程心率监控。训练课前、训练课后即刻、训练后3 h、12 h、24 h分别抽取静脉血,测定hs-c Tn I。结果:1)总体来看,运动员的hs-c Tn I于运动后即刻升高,运动后3 h达到最高,运动后12 h下降,至24 h完全恢复。2)男女运动员TRMP无显著性差异,男女运动员运动后即刻、运动后3 h以及运动后12 h的hs-c Tn I均高于运动前,差异有统计学意义(P0.01)。运动后各时间点男女间hs-c Tn I无显著性差异(P0.05)。3)优秀运动员与普通运动员的TRIMP无显著性差异(P0.05)。优秀运动员组运动后即刻、运动后3 h、12 h的hs-c Tn I显著高于运动前(P0.01),运动后24 h恢复到运动前水平(P0.05)。普通运动员运动后即刻、运动后3 h、12 h均高于运动前,差异有统计学意义(P0.01),运动后24 h仍显著高于运动前(P0.05)。优秀运动员的hs-c Tn I在运动后即刻、3 h、12 h、24 h均显著低于普通运动员(P0.05)。结论:一次柔道技术实战课可以诱导运动员心肌肌钙蛋白释放增加,可用hs-c Tn I进行柔道运动员训练课的心肌损伤监控。
[Abstract]:Objective: to explore the changes of I(hs-c TN I in judo athletes after a technical training session during winter training, and to provide methods and means for monitoring cardiac function during judo training. Methods: 12 outstanding judo athletes (half male and half male) and 12 ordinary judo athletes (half male and half male) were studied. Venous blood samples were taken before training, immediately after training, and 3 hours after training for 12 hours and 24 hours after training. Hs-c tin I was measured. Results (1) overall, hs-c TN I increased immediately after exercise, reached the highest level at 3 h after exercise, decreased at 12 h after exercise, and recovered completely at 24 h.) there was no significant difference in TRMP between male and female athletes, and there was no significant difference between male and female athletes immediately after exercise. The hs-c TN I at 3 h after exercise and 12 h after exercise were higher than those before exercise, and the difference was statistically significant (P 0.01). There was no significant difference in hs-c TN I between male and female at different time points after exercise (P 0.05). 3) there was no significant difference in TRIMP between elite athletes and ordinary athletes (P 0.05). The hs-c TN I in the elite athletes group was significantly higher than that in the pre-exercise group at 3 h and 12 h after exercise, and recovered to the pre-exercise level at 24 h after exercise. Immediately after exercise, 12 hours after exercise, the difference was statistically significant (P 0.01), and 24 hours after exercise was still significantly higher than that before exercise (P 0.05). The hs-c TN I of the elite athletes was significantly lower than that of the ordinary athletes at 3 h and 12 h and 24 h after exercise. Conclusion: a practical judo course can induce increased cardiac troponin release, and hs-c TNI can be used to monitor myocardial injury in judo athletes training class.
