The Comparison of Total Antioxidant Capacity and Glutathione Peroxidase and Lipid Profile Serum of Endurance Swimmers and Non-Athletes males

It is believed that the amount of antioxidant enzymes activity increases during the moderate aerobic exercise and protects the tissue against the oxidative stress. The aim of the current study is to compare the endurance swimmers with non-athletes males regarding three factors: Total Antioxidant Capacity (TAC), Glutathione Peroxides (GPX), and serum lipid profile. For the purpose of the study, 25 endurance swimmers participated in swimming exercises for three 45 minutes sessions every week seven months before the study. The 23 non-athletes selected did not participate in any regular physical exercises in the same period. TAC was measured according to FRAP method, GPX was measured by controlling the reaction of Autoxidation Pyrogallol, and Profile Lipid indexes density was measured according to Pars company’s Enzymatic standard kit methods. The result showed that the amount of TAC, GPX, and maximal oxygen uptake(VO2max) of the swimmers was significantly higher than the non-athletes(P < 0.05), but their BMI and fat body percent were significantly lower than the nonathletes(P < 0.05). Moreover, it was observed there is not any significant difference between Uric Acid, Bilirobin, and Lipid indexes of the two groups (P > 0.05). Therefore, performing special swimming exercises regularly result in improvement and fortification of antioxidant system against the oxidative stress produced during exercise.
