The study was conducted in order to study the free radicals formation of competition in elite fighters and the antioxidant system effect in the experimental group of students at the University of Niğde, Physical Education and Sports High School, the average age of 21,33±2,61 years, coloring, 71±O,03cm. The weight average is 73.66 ± 7.53kg, and is made up of 18 healthy, volunteer male fighters. Students who participated in the study have been controlled their eating habits. Within the framework of the ftL.A rules, each player has played a competition 5 times with a half-hour interval. No exercise is allowed three days before the match. Study participants took a venous blood sample from the front edge before the match (Mo,,), a total of 5 matches immediately after the match (Mson), 24 hours after the match (M24) and 48 hours after the match (M4s). The total antioxidant capacity (TAC), melondialdehyd (MDA) and the total sulfidril group (RSH) in the serum wereined. The study found that MDA and TAC had significant increases, while RSH had significant decreases. The competition causes significantly oxygen stress in the competitors, while the total oxygen capacity increases and non-enzymatic antioxidant capacity decreases. In this context, it may be thought to be effective in reducing oxygen stress that is formed by the vitamin and other ergogens, which are the pre-competitive non-enzymatic antioxidant effect. Keywords: Struggle, Antioxidant Capacity, Oxygen Stress ABSTRACT This study has been done to examine the effect of struggle match lo the free radical fonuation and antioxidant system. The experiment group consists of elite volunteer wrestlers from Physical Training and Sport Academy of Nigde University, aged between 2l,33±2,6l years old, average height 71±O,03cm, average weight 73,66±7,53kg. The diets of subjecls taking part in the study have been recorded the same feeding program. Within the FILA rules, each subjects perfonned 5 wrestlings. No exereises have been permitted within 3 days before the battle. Venous blood samples were taken from the subjects before match (MOD)' right after total 5 matches imrnediately after the mach (Mson), 24 hours later(Mu), 48 hours later (M48) after the match and, The total antioxidant capaciry (TAC), malondialdehyde (MDA), total sulphydryls group (RSH) levels were deterınined after samples were centrifuged. In the study it was seen that there are significant increase in MDA and TAC values and significant drop in RSH values. Wrestling match causes significant oxidant stress, making the total antioxidant capacity increase and non-enzymatic antioxidant capacity decrease. Thus, it can be thought that it is effectiye to support wrestlers with vitamins which non-enzymatic antioxidant effect and other ergogens to decrease oxidan stress.
