Objective: In this study, it was aimed to evaluate the effects of short-term intensive exercise on liver enzymes and serum lipid levels with kick boxing athletes. Methods: 23 voluntary athletes who were between the ages of 15-46 and who engaged in kick–boxing have taken place this study. Athletes were made to do 45 minutes of warming-up, breathing, and stretching and 50 minutes of technical and tactical practices and then they were made to do a training match, which is equal to a 2 minutes 3 circuits (1 minute rest) kick-box match. In venous blood samples which were taken from athletes before and after training, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma glutamine transpeptidase (GGT), enzyme activity and total cholesterol, high-density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) and triglycerides serum levels were analyzed via spectrophotometric method in Beckman Coulter AU 5800 auto analyzer. Body composition measurements of athletes were made with Tanita TBF 300 brand device, which works with bio-impedance analysis (BIA) system. Results: As a result of our study, statistically increases in serum ALT, AST, ALP and GGT enzyme activities and in serum total cholesterol, HDL-C and LDL-C levels were detected following short-term intensive exercise, but no significant difference was observed in TG levels after intensive exercise. Conclusion: The blows to the abdomen during kickboxing sports competitions result in increased liver enzymes and increased serum lipids may occur to meet energy demand of the body during exercise. Key words: Training, kickboxing, liver enzymes, lipids
