本研究主要在探討12週強力適能瑜珈訓練對停經婦女荷爾蒙濃度與抗氧化能力之影響。以30名身心健康的停經婦女為研究對象，隨機分配15名為實驗組(平均年齡55.20 ± 5.77歲，身高154 .17±4.44公分，體重55.13 ±6.12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%HRmax。 15名為對照組(平均年齡56.53 ± 5.11歲，身高155 .17±4.03公分，體重56.31 ±6.67公斤)，並不接受運動訓練。全體受試者於實驗期間需每日配戴計步器及填寫飲食及體重變化紀錄表，以監控平日身體活動量及飲食控制。實驗前、後測，採取受試者唾液及血液樣本，以檢驗唾液中助孕素、睪固酮、可體松，及血液中血紅素結合蛋白。將所得數據資料，以單因子共變數進行分析。
結果發現：
一、助孕素濃度有明顯增加的情形(p<.05)。
二、睪固酮、可體松濃度及睪固酮與可體松比值並沒有明顯差異情形
(p>.05)。
三、血紅素結合蛋白濃度有明顯增加的情形(p<.05)。
本研究所得結論為12週中等強度的強力適能瑜珈對停經婦女可能有助於：(一)可降低冠心疾病、乳癌、子宮內膜癌的風險。(二)能避免因過度訓練所引發的疲勞、緊張、壓力等現象。(三)能提升抗氧化的防禦能力。

The purpose of this study was to investigate the effects of power fitness yoga training on the concentrations of hormones and anti-oxidative status in postmenopausal women. Thirty healthy postmenopausal women participants were randomly assigned to two groups .Fifteen subjects were in the experimental group (age=55.20 ± 5.77yrs, ht=154 .17±4.44cm, wt=55.13 ±6.12kg), who attended the power fitness yoga training at 74.93 ± 3.31%HRmax for 90 minutes per day, 3 days per week for 12 weeks. Fifteen subjects were in the control group (age=56.53 ± 5.11yrs, ht=155 .17±4.03cm, wt=56.31 ±6.67kg), who were arranged not to accept the training. All subjects were instructed to carry pedometers , to record dietary diet and weight for the duration of the study, and to monitor their daily physical activity and dietary control. Pre-and-post tsets were employed to measure the concentrations of salivary progesterone, testosterone, cortisol and serum haptoglobin. The data were assessed by one-way analysis of covariance(one-way ANCOVA).
The results of the study were shown as follows:
1. The concentration of progesterone was significantly increased (p<.05).
2. The concentrations of testosterone, cortisol, testosterone /cortisol ratio( T/C ratio) did not change significantly (p>.05).
3. The concentration of haptoglobin was significantly increased (p<.05).
The findings of the present study suggest that 12 weeks of moderate-intensity power fitness yoga in postmenopausal women may be helpful: (1) to reduse the risks of coronary heart disease, breast cancer, endometrial cancer; (2) to avoid being tired, nervous, and stressful due to overtraining ; (3) to enhance anti-oxidative status.
