Determination of changes in antioxidant levels of elite grade male athletes and ski runners doing endurance training

This study was performed to investigate the effect of the activity at high-altitude on carbonic anhydrase (CA), catalase (CAT), erythrocyte glutton peroxides (GSH), methylenedioxy-methylamphetamine (MDA), superoxide dismutase (SOD) enzyme levels.8 sedentary males, 9 male athletes and 9 male skiers between the ages of 17 – 19, 26 healthy volunteers took part in this study. Athletes doing athletics and the sport of skiing in the experimental group have been selected among athletes who are doing long duration endurance training, training for 2 hours per day and 7 days a week. In addition, they were provided cardio practice for 3 days a week. The sedentary group has been chosen from non-elite athletesdoing3 or 4 day soft raining in a week. SPSS 16program was used to evaluate data and analysis were made by Wilcox on test. CA,CAT and GSH enzyme levels of the malecontrol group, male athletes and male skiers have been determined after taking blood samples and a significant difference has not been observed among values according to p<0,05. However, when looking at the MDA and SOD values, a significant correlation has been observed among research groups according to p<0,05. The results achieved in this study yielded meaningful outcomes on the antioxidant defence of MDA and SOD of athletes doing endurance training. Based on these results; the requirement of consideration of changes in the MDA and SOD values of endurance sport commissioned individuals can be expressed as the recommendation of our work.
