目的：本研究主要在探討12週強力適能瑜珈訓練對停經婦女抗氧化能力之影響。方法：以24名身心健康的停經婦女為研究對象，隨機分配12名為實驗組（平均年齡56.26±5.85歲，身高154.75±4.38公分，體重55.88±6.72公斤），實驗組受試者進行每週三次、每次90分鐘，為期12週的強力適能瑜珈課程訓練，其運動強度為74.93±3.31% HR(下標 max)。12名為對照組（平均年齡56.77±5.51歲，身高155.43±4.25公分，體重56.17±6.84公斤），並不接受運動訓練。實驗前、後測，採取受試者血液樣本，以檢驗血液中丙二醛、過氧化物歧化酶、穀胱甘肽過氧化酶、穀胱甘肽。將所得數據資料，以單因子共變數進行分析。結果：本研究發現實驗組經過12週的強力瑜珈訓練後，過氧化物歧化酶與穀胱甘肽過氧化酶的活性顯著地高於控制組(p<.05)。抗氧化物質穀胱甘肽及氧化傷害指標丙二醛則沒有產生變化(p>.05)。結論：本研究證實12週中強度的強力瑜珈訓練對於停經婦女具有提升抗氧化酶的作用，但氧化傷害指標丙二醛則不會造成影響。

Purpose: The purpose of this study was to investigate the effects of 12-week power fitness yoga training on the antioxidant capacity in postmenopausal women. Method: Twenty four healthy postmenopausal women participants were randomly assigned to two groups. Twelve subjects were in the experimental group (age=56.26±5.85 yrs, Ht=154.75±4.38 cm, Wt=55.88±6.72 kg), who attended the power fitness yoga training at 74.93±3.31%HR(subscript max) for 90 minutes per day, 3 days per week for 12 weeks. Twelve subjects were in the control group (age=56.77±5.51 yrs, Ht=155.43±4.25 cm, Wt=56.17±6.84 kg), who were arranged not to accept the training. Blood samples were taken before and after the experimental to test the blood malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione (GSH). The data were assessed by one-way analysis of covariance (one-way ANCOVA). Result: The findings of this study showed that the concentration of SOD and GPx in the experimental group were significantly increased than those of control group (p<.05). However, antioxidants glutathione and malondialdehyde oxidative damage indicators did not change (p>.05). Conclusion: It is concluded that 12 weeks of moderate intensity power fitness yoga training in postmenopausal women could enhance the activities of antioxidant. However, indicators of oxidative damage malondialdehyde are not affected.
