    Effects of endurance training on exhaustive exercise-induced oxidative stress markers
    (ACADEMIC JOURNALS, 2011) Revan, Serkan; Erol, Ali Emre
    This study was aimed to investigate the effects of endurance training on lipid peroxidation and antioxidant enzyme levels in young adults. Twenty four male students participated in this study. Subjects were divided into two groups as training group (n=12) and control group (n=12). Subjects in the training groups performed running exercise 25 to 60 min/day, three days/week for eight weeks at an intensity of 50 to 70% of target heart rate. Blood samples collected at rest and after exhaustive exercise before and after 8 weeks, were analyzed for the determination of plasma lipid hydroperoxide (LOOH) level, and activities of glutathione peroxidase (GPx), catalase (CAT) and lactate dehydrogenase (LDH). LOOH level in the training group significantly decreased after the post-training period (p<0.05), but did not alter in the control group (p>0.05). LDH activities significantly increased both control and training groups after the exhaustive exercise (p<0.05). LDH activity was found significantly higher in control group than training group both at rest and after exhaustive exercise (p<0.05). GPx was not significantly altered by training and exhaustive exercise in both groups (p>0.05). In the training group, exhaustive exercise significantly increased CAT level after training period (p<0.05). Consequently, it can be said that endurance training is effective in prevention of lipid peroxidation caused by exhaustive exercise.
