The Effects on the Antioxidant Immune System of Intensive Training Period of Female Athletes and Female Ski Runners

This study is designed to investigate the effects of physical activity on antioxidant system parameters. Subjects were composed of 26 elite level runners who regularly train in Agri including 9 female athletes, 9 female ski runners, and 8 sedentary between 17 – 18 years of age. The research was conducted during a season by making athletes cardio training 3 days a week and cross training 4 days a week. The blood samples were analyzed with respect to the results of antioxidant system parameters MDA (Malondialdehyde), SOD (superoxide dismutase), CAT (Catalase), CA (carbonic anhydrase), GSH (glutathione peroxidase) enzyme activation. An increase has been observed in SOD enzyme activity and level of MDA after training according to the resting state and this increase was statistically significant (p<0.05). In this study, no significant difference has been found in CA, CAD and GSH levels after training. Determined decrease in CA, CAD and GSH levels suggests that reducing the free radicals and consequent lipid peroxidation as a result of the strengthening of the antioxidant defense system by a workout. These results may indicate that aerobic training improves the ability of adaptation to oxidative stress.
