Changes in plasma creatine kinase activity and urea concentration monitored daily during training of elite wrestlers

Abstract

The daily work load (DWL), blood urea concentration and creatine kinase (CK) activity in plasma were monitored daily for 8 days in 6 free‐style elite wrestlers. Both of the biochemical measures were correlated with DWL of the preceding day. Examination of the partial correlation coefficients computed among the three variables studied showed that CK activity was significantly correlated with DWL (r = 0.52; p ≤ 0.001) while urea concentration was not (r = 0.08; p > 0.05). This suggests that plasma CK activity is a direct effect of exercise while plasma urea is only an indirect index of the experienced work load. Nevertheless, both variables may serve as a diagnostic tool in assessing the risk of overloading in wrestlers' training.
