两种模拟训练前后男子马拉松运动员CK、BU和心电图∑T／R的相关性

The correlation between CK, BU and ECG ΣT/R with respect to male marathoners before and after two types of simulated training

通过测定模拟大运动强度训练和大运动量训练前后男子马拉松运动员肌酸激酶(CK)、血尿素(BU)指标和心电图ΣT/R指标的变化规律,探讨指标间的相关性,以期为运动员提供无创监控。将8名马拉松运动员分2次进行大运动强度训练和大运动量训练,训练前后取血及心电图指标进行测试分析。结果:在大运动强度训练后,运动员CK指标与心电图ΣT/R指标呈负相关,在日常训练中可以使用心电图ΣT/R这一简易、无创指标代替CK指标进行强度训练监控;在大运动量训练后,运动员BU指标与心电图ΣT/R指标之间基本不存在相关性。

By measuring the pattern of changes of such indexes as creatine kinase （CK）, blood urea （BU） and ECG ∑T/R with respect to male marathoners before and after simulated high intensity training and heavy load training, the authors probed into the correlation between the said indexes, hoping to provide marathoners with trauma free monitoring. The authors put 8 marathoners into high intensity training and heavy load training twice, sampled their blood before and after the training, tested and analyzed ECG indexes, and revealed the following findings： after high intensity training, the CK index and ECG ∑T/R index with respect to the marathoners showed a negative correlation; in day to day training such a simple and trauma free index as ECG ∑T/R can be used to replace the CK index for the monitoring of intensity training; after heavy load training, there is basically no correlation between the BU index and ECG ∑T/R index with respect to the marathoners.
