초록

The purpose of this study is to examine the effects of endurance exercise training on antioxidant capacity and lymphocyte DNA damages caused by cardiorespiratory endurance and 85%V·O_2max all-out exercise by conducting an 8 weeks endurance exercise training for 19 healthy female undergraduates. To achieve the purpose of this study, treadmill running was conducted at the intensity of 70%HRR for 8 weeks. Before and after the training, 85%V·O_2max all-out exercise test was conducted. At the 85%V·O_2max all-out exercise test, blood samples were taken 5 times respectively before and after the training. With the samples, serum lactate, plasma SOD, and lymphocyte DNA damages were analyzed. The results of the study showed that V·O_2max and exercise duration increased significantly(p<.05) after the 8 weeks endurance exercise training. It was also showed that serum lactate caused by high intensity acute exercise decreased significantly at each time of blood taking after the endurance exercise training(p<.05). There were significant differences in the activity of plasma SOD and lymphocyte DNA damages after the endurance exercise training(p<.05). It was also found that there are significant correlations between the changes of V·O_2max caused by the 8 weeks endurance exercise training and the changes of plasma SOD, %DNA in the tail and tail moment. Conclusively, 8 weeks regular endurance exercise training can decrease DNA damages by increasing cardiorespiratory endurance and the activity of anti-oxidant and relieving oxidative stress.
