The activity levels of superoxide dismutase (SOD, EC 220.127.116.11), Catalase (EC 18.104.22.168) and status of lipid peroxidation in male athletes and deskbound population was investigated. Both the groups i.e. deskbound (D group) and athlete (A group) consist of thirty subjects each. Sedentary subjects are included in group D who are not involved in regular physical activity and Group A includes endurance athletes of 15 Km walk involved in regular physical activity. The blood serum was used for activity levels of enzymes and other parameters. The serum catalse, superoxide dismutase & malondialdehyde were significantly (P< 0.05) high in group A (athletes) as compare to group D (Deskbound). Due to continuous physical activity both oxidative stress and antioxidant capacity increased in athletes as compared with deskbound controls. Pakistani endurance athletes have increased markers for malondialdehyde and antioxidant enzyme compared to their desktop counterparts. Increased lipid peroxidation and the antioxidant status of Pakistani athletes may be due to regular physical activity and prolonged endurance.
