RENAL AND LIVER FUNCTIONS ACID MUSCLE INJURIES DURING TRAINING AND AFTER COMPETITION IN THAI BOXERS

Objective-To observe whether there are any injuries to muscle and dele terious effects on the liver and kidneys during training and after com petition in Thai boxers. Methods-Serum levels of intracellular enzymes and specific markers in the urine were measured during training and a fter fighting in Thai boxers. Results-During the training period, the activities-of muscle enzymes were significantly increased whereas thos e of the liver enzymes and creatinine clearance were not changed. Afte r a match, on the other hand, both liver and muscle enzyme activities were elevated but renal function was decreased. Conclusions-The traini ng protocol for Thai boxers has virtually no deleterious effect on liv er and renal function, but damage to skeletal muscle cells may occur. However, competition may cause muscle injury without any obvious damag e to the liver and kidneys.
