目的：文獻報告台灣社區居住的老年人約26%有憂鬱症狀，本研究在探討利用就近的社區活動中
心等適當場地，持續八週的小團體式運動訓練對居住社區老人之憂鬱症狀、生活功能和生活品質
的成效。方法：以方便取樣徵得24名65歲以上之社區老人（平均年齡80.8±6.7歲），隨機分配至運動組與控制組。運動組在治療師監督指導下接受小團體（每次2至4人）每週3次、每次約30-40分鐘、中等強度、結合有氧運動、上下肢大肌群體操式的伸展與阻力運動訓練，強度為自覺用
力係數12-14，阻力則以沙包或彈力帶適時作調整。測量變項包括短式智能評估、台灣老年憂鬱
量表、生活功能（活動限制量表、30秒重覆座椅起立測試、計時起走測試、六分鐘行走測試）與
生活品質（SF-36台灣版）。以重複變異數分析（repeated measures）檢定兩組對於各觀測因子在介入前後的差異，並以治療意願做分析，另以皮爾森相關係數探討依變項改變量之間的相關性。結果：相較於控制組，運動組僅在30秒重覆座椅起立的測試有顯著進步（p<0.05），組內的變化包括運動組六分鐘行走距離顯著增加、控制組座椅起立測試顯著退步，其他變項無明顯差異。六分鐘行走測試的改變量則與計時起走測試的改變量有顯著負相關（r=-0.49），此外，認知功能的改變和計時起走測試改變有顯著負相關（r=-0.64）、並與六分鐘行走測試的改變有正相關（r=0.42）。結論：居住在社區的老年人在八週的小團體運動訓練後，生活功能之重覆座椅起立測試的表現有明顯進步，認知、情緒、生活品質則未有明顯改變。（物理治療 2009;34(3):209-218）

Purpose: Depression is commonly seen in the community-dwelling elderly in Taiwan with a reported prevalence rate of 26%. The purpose of this study was to investigate the effects of exercise training on depression symptoms, physical functions, and quality of life in the communitydwelling
elderly. Method: A convenient sample of 24 elderly subjects living in the community aged 65 years or older was recruited and randomized into exercise group and control group. Participants in the exercise group received a progressive and structured, small-group comprehensive exercise training, including components of aerobic, resistance, and flexibility exercise, 3 times a week, 30-40 min a session at intensity of 12-14 in rate of perceived exertion (RPE) for 8 weeks under supervision. Sandbag and/or theraband were used to adjust the training load. All subjects were assessed by Taiwanese Geriatric Depression Scale (TGDS), Mini-Mental State
Examination (MMSE), Groningen Activity Restriction Scale (GARS), and hort-form 36 (SF-36) at baseline and 8 weeks after. In addition, tests of 30-second chair sit-to-stand (STS), timed up and go (TUG), and six-minute walk (6MW) were used to evaluate their physical function status. Repeated measures ANOVA were used to investigate the effects of time and exercise intervention on the variables of interest. The intention-to-treat principle was applied in data analysis. Relationships between the changes of each variable were analyzed by Pearson correlation coefficients. Results: Compared to the control group, subjects in the exercise groups improved in the STS performance (p<0.05). Significant changes within group included the increase in 6MW distance in the exercise group and the decrease in the performance of STS in the control group. No other significant within- or between-group differences were found. Changes in MMSE were significantly related to the changes in TUG and 6MW in addition to the significant correlation between changes in TUG and 6MW. Conclusion: The community-dwelling elderly can benefit from an 8-week exercise training program in small groups with improvements mainly in repeated sit-to-stand physical function test and no obvious changes in emotion, cognition and quality of life dimensions were found in this study.
