Abstract - Effect of endurance training on biomarkers of oxidative stress in male wrestlers
In this research we evaluate the influence of continuous endurance training program on oxidative stress in male athletes. Participants in this study were wrestlers (age 21.9 ± 3.5, 11.7 ± 4.0 sport experience 11.7 ± 4.0, height 176.7 ± 6.6 cm, body mass 79.6 ± 13.5 kg) from Serbian national team. All of them (n=14) have had same training program in period of four weeks, which included training regime on 75-85% HR max continuous aerobic activity, in duration of 60 min, 3 days per week. Blood samples were collected in the morning before and day after the training program. After the training program we examined activity of the enzymes: superoxide dismutase (SOD), glutathione reductase (GSH-R), glutathione peroxidase (GSH-Px), catalase (CAT) and total antioxidant activity (TAC). After applied the endurance training program TAC decreased significantly (p<0.05), but at a referent level which could not have a negative effect on health or performance of athletes.
