A Study of the effect of exercise on the levels of some antioxidants and lipid peroxidation in Physical Education students

Abstract

The research included a study of the effect of exercise on the levels of enzymatic, non-enzymatic antioxidants and lipid peroxidation among physical education students. This was achieved through the determination of the activities of superoxide dismutase (SOD)and glutathione peroxidase (GPx) as enzymatic antioxidants, glutathione (GSH), uric acid and vit. E concentration as non-enzymatic antioxidants in addition to measuring malondialdehyde concentration (MDA) as an indicator of lipid peroxidation.The study was applied on (24) blood serum samples of physical education students in the fourth stage aged between (18-22) years and compared with (21) blood serum samples of students with the same age not exert exercise as control group. The results showed a significant increase in the concentration of MDA and a significant decrease in the concentration of glutathione, uric acid and vit. E. The results also showed a non-significant reduction in the activities of (SOD) and (GPx) in the study group compared to the control groupKey words : exercise, malondialdehyde, Glutathione, Superoxide dismutase, vit.
