本研究以48名未從事任何運動訓練的大專女生（平均年齡18.73±0.54歲，平均身高158.91±6.23公分，平均體重51.49±5.75公斤）為受試者，隨機分派至太極拳組(n=12)、瑜珈組(n=12)、恰恰組(n=12)與對照組(n=12)，進行為期共十週的縱向式研究，每週實施三天，每天40分鐘太極拳運動、瑜珈運動或恰恰運動，以不運動為對照，探討太極拳運動、瑜珈運動與恰恰運動對大專女生抗氧化能力的影響。各指標前後測間的差異以相依樣本t-test 檢驗。結果發現，實施太極拳運動後，肌酸激酶(creatine kinase, CK)並無明顯增加(p>.05)，乳酸脫氫酶(lactate dehydrogenase, LDH) 與丙二醛(malondialdehyde, MDA)明顯降低(p<.05)，過氧化物歧化酶(superoxide dismutase, SOD)與谷胱甘肽過氧化物酶(glutathione peroxidase, GPX)則明顯升高(p<.05)。實施瑜珈運動後，個體的LDH明顯降低(p<.05)，至於CK、MDA、SOD與GPX則並無明顯的變化(p> .05)。實施恰恰運動後，個體的CK、LDH與MDA明顯提高(p<.05)，SOD與GPX明顯降低(p<.05)。對照組的各指標實驗前後並無明顯改變(p>.05)。本研究結果顯示太極拳運動可以降低個體的氧化壓力，提高抗氧化能力；瑜珈運動在某方面可以降低個體的氧化壓力；而恰恰運動則會導致氧化性傷害，並且降低個體的抗氧化能力。

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.
