Muscle damage in intensive preparation period for elite wrestlers – biochemical assessment

PURPOSE: Preparation training of elite-class wrestlers is a highly intensive physical activity. Such activity leads to muscle tearing and the raise of concentration of certain biomarkers in blood. Some of these biomarkers indicate heart muscle or liver damage, so what we are interested in is whether biochemical tests can reveal if a highly intensive activity such as wrestling preparations at the elite level is harmful to the heart muscle and liver. METHODS: Eleven elite Croatian wrestlers have undergone seven-days preparation and 24 hours after the preparation the subjects had their blood sampled (CK, CK-MB, ALT, AST and GGT). The differences between the level of analysed biomarkers and the upper reference limits have been tested by Wilcoxon Matched Pairs test. Pearson coefficient correlation has been calculated in order to determine the connection between CK and CK-MB in addition to the CK-MB percentage in the total value of CK. RESULTS: The research revealed that AST 273 enzyme was significantly increased (Z=2, 31 ; p=0, 02), but since ALT and GGT enzymes are not, we may conclude there were no liver damages. There is a high correlation between CK and CK-MB (r=0, 75), while the percentage of CK-MB isoenzyme within the total CK percentage is 2, 23%, revealing there were no heart muscle damages. CONCLUSION: Based on the conducted research, we may draw a conclusion there is no health risk referring to liver or heart muscle damage in elite wrestlers during the intensive preparation period.
