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 ΣT/R index with respect to the marathoners showed a negative correla-tion; in day to day training such a simple and trauma free index as ECG ΣT/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 ΣT/R index with respect to the marathoners.
