背景：心臟缺血性病變危險因子包含高血壓、身體活動量不足、高血脂、肥胖、冠心病家族史等，而它有一段較 長的無症狀潛伏期，是預防措施介入的最佳時期。 目的：本研究乃測試12週團體氣功運動在修正心臟缺血性病變危險因子之成效。 方法：採叢聚隨機控制實驗及重複測量研究設計，以社區健康營造中心為隨機分派群組，將符合收案條件的研究 對象分為實驗組(n = 84)施以12週的團體氣功運動訓練，及無氣功運動介入的控制組(n = 61)。血壓、脈搏 速率、呼吸速率、身體質量指數、腰臀圍比及簡易老人憂鬱量表分別於前測、介入後6週、12週及16週收集， 而總膽固醇／高密度脂蛋白和低密度脂蛋白／高密度脂蛋白比值，則是於介入前和介入後12週採集血液檢 體。 結果：線性混合模式分析結果發現，實驗組的憂鬱程度、收縮壓、脈搏速率、呼吸速率及總膽固醇／高密度脂蛋 白比值等，和對照組比較有顯著改善，且憂鬱、脈搏速率及呼吸速率的改善效果可維持一個月。 結論/實務應用：本研究發現，具心臟缺血性病變危險因子之中老年人，執行12週團體氣功運動能有效降低其收縮 壓、緩解憂鬱情緒及降低總膽固醇／高密度脂蛋白比值。故氣功運動可視為預防心臟缺血性病變的保護因 子，並作為缺血性心臟病高危險群者的自我放鬆和健康促進措施之一。

Background: The risk factors of ischemic heart disease (IHD) include hypertension, inactivity, dyslipidemia, obesity, family history of coronary heart disease, and other conditions. The long asymptomatic latent period in IHD is the best phase in which to undertake preventative interventions. Purpose: The aims of the present study were to examine the effects of a 12‐week group Qigong exercise on modifying the risk factors of IHD. Methods: A cluster‐randomized controlled trial and repeated measures were used. Eligible participants were recruited from several different community health centers. Participants were grouped by their associated center, with each center randomly assigned to either the experimental group (n = 84 participants) or control group (n = 61 participants). The participants in the experimental group were invited to participate in a 60‐ minute group Qigong exercise session for three times each week over a 3‐month period. The control group did not receive any Qigong exercise intervention. Blood pressure, pulse rate, respiratory rate, body mass index, waist hip ratio, and Short‐Form Geriatric Depression Scale were collected at baseline and at the 6‐ week, 12‐week, and 16‐week follow‐ups. Total cholesterol/high‐density lipoprotein (TC/HDL) and low‐density lipoprotein (LDL)/HDL were assessed at baseline and at the 12‐week posttest only. Results: Linear mixed model analyses revealed that the Qigong exercise participants had improved significantly in terms of systolic blood pressure, pulse rate, respiratory rate, depression states, and TC/HDL ratio in comparison with their control group peers at the 12‐week posttest. Moreover, these positive effects on depression, pulse rate, and respiratory rate continued through the 16‐week posttest. Conclusions / Implications for Practice: For community adults aged over 40 years with risk factors of IHD, a 12‐ week group Qigong exercise may effectively reduce systolic blood pressure and depression as well as modify TC/ HDL. Qigong exercise may protect people with risks of IHD and be used as a self‐relaxation technique and health promotion intervention.
