Effect of Sparring Training Model on Liver Enzymes and Muscle Damage in Boxers

Abstract

The purpose of this study is to examine the acute effect of sparring training model on liver enzymes and muscle damage in boxers.14 voluntary athletes engaged in box (23.71±1.44 years of age; 167±5.89 cm; 62.05±8.89 kg) participated in the study. Sparring training model composed of warm-up (25 minutes), main part (30 minutes) and cool-down (15 minutes) exercises was applied to the boxers. The main theme of the study is composed of the free sub-stroke sparring training model in the liver region. Sparring training applied in the liver region and consisting of 3-minute time periods was repeated 3 times with a 1-minute interval as in the punch bag training. In venous blood samples taken from the study group before and after sparring training, AST, ALT and GGT enzyme activities and CK and LDH levels were analyzed with the spectrophotometric method in Beckman Coulter AU 5800 auto analyzer. Data were analyzed in SPSS 22.0 package program. The significance level was accepted as p<0.05 in statistical evaluations. Normal distribution of data was determined with Shapiro-Wilk test. Paired t-test was used in the statistical analysis of normally distributed data. Comparing AST, ALT, GGT, LDH and CK values of boxers before and after the training, it has been observed that there is a significant increase in AST, LDH and CK values after the training (p<0.05) and significant decrease in GGT values (p<0.05) while there is no significant difference in ALT values (p>0.05). In conclusion, it has been determined that sparring training model applied to boxers affects liver enzyme levels in them and significant increases occur in CK and LDH. More comprehensive prospective studies are required in order to establish the possible damage of punches to the liver region on liver in boxers.
