Abstract :
Despite the beneficial effects of physical activity on health and disease prevention, some studies suggest that physical activity increases the production of reactive oxygen species; therefore the aim of the present study was to compare the effect of acute aerobic activity on the oxidative and antioxidant status of normal and obese women. For this purpose twenty subjects non-athlete women (10 normal weight and 10 obese) were selected randomly. Subjects participated in the Bruce Treadmill Test Protocol (acute aerobic activity). Body fat percentage of subjects were measured using calipers and by measuring the thickness of the triceps skin folds of the females according to the Jackson and Pollock equations. Blood samples were collected from both groups before and after the activity to measure changes in Malondialdehyde and total antioxidants. The results showed that the levels of malondialdehyde increased significantly in both groups immediately after the pretest activity, but total antioxidant levels did not change significantly between the two groups. Aerobic exercise in non-athlete subjects results in increased levels of malondialdehyde which is an oxidant index. Acute aerobic activity overproduces free radicals and reduces antioxidant resources, Increases oxidative stress, weakens antioxidant capacity, and increases oxidative damage to biological macromolecules including membrane proteins and lipids (malondialdehyde).
