INTRODUCTION: Physical activity is known to induce oxidative stress and tissue damage in individuals subjected to intense exercise. It is supposed that different exercises would result in various oxidative stresses and antioxidative capability. The purpose of this study was to investigate the influence of 10 weeks Taiji, Yoga and Cha Cha training on changes in antioxidative capability of college female students. METHODS: Forty-eight college healthy female students (mean age 18.73±0.54 yr, mean height 158.91±6.23 cm, and mean weight 51.49±5.75 kg) volunteered to participate in the study. They were randomly assigned to one of four treatment groups: a Taiji group,a Yoga group, a Cha Cha group and a control group with no training. The three experimental groups received a regular schedule on Taiji, Yoga and Cha Cha training (40 minutes each time, three times a week) for ten weeks. All subjects signed an informed consent form prior to participation in the training. Fasting blood samples were drawn before and after the 10-week training program for determining of the creatine kinase (CK), lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GPX). A dependent t-test was used to compare the differences between pretest and post-test. RESULTS: It was found that the blood levels of SOD and GPX increased significantly (p<.05), while LDH and MDA decreased significantly (p<.05) for the Taiji group at the end of the training, as compared to the onset. It was also noted that LDH decreased significantly (p<.05), while the other indexes remained unchanged (p>.05) during the course of study for the Yoga group. As for the Cha Cha group, concentrations of CK, LDH, and MDA increased, and SOD and GPX decreased significantly post-training compared with pre-training samples (p<.05). CONCLUSIONS: The results demonstrated that Taiji is a moderate exercise, which will enhance antioxidative capability and may well reduce oxidative stress in the college female students. The obtained results of this research also revealed that Cha Cha may induce muscle damage and causes changes in an elevation of oxidative stress.
