Evaluation of oxidative status in short-term exercises of adolescent athletes

Journal Title: Biology of Sport - Year 2010, Vol 27, Issue 3

Abstract

The aim of the study was to evaluate the effects of short-term exercise on total antioxidant status (TAS), lipid hydroperoxide (LOOHs), total oxidative status (TOS) and oxidative stress index (OSI) in adolescent athletes. A total of 62 adolescent participated in the study. Athletes were trained regularly 3 days a week for 2 hours. All subjects followed a circuit exercise program. Blood samples were collected just before and immediately after the exercise program. Antioxidant status was evaluated by measuring the TAS level in the plasma. Oxidative status was evaluated by measuring the total peroxide level. The percentage ratio of TAS to total peroxide level was accepted as the OSI. Plasma triglyceride, total cholesterol, LDL, HDL and VLDL were measured by automated chemical analyzer using commercially available kits.There was a significant increase in TOS (p<0.05) and OSI (p<0.01) levels and a significant decrease in TAS levels (p<0.01) compared to the resting state. There were no significant changes in LOOHs levels before and after the short-term exercise. After short-term exercise, the balance between oxidative stress and antioxidant status moves towards oxidative stress as a result of increasing oxidants and decreasing antioxidants.
