目的：本研究旨在以多尺度熵探討環狀運動介入對高齡者終止步態及靜態平衡穩定度的影響。方法：以55位55-80歲外觀健全並能獨自行走的高齡者為對象，茲將對象分為：運動習慣組平均年齡為66.1±8.0歲、身高為159.8±7.0公分、體重為62.8±9.0公斤；環狀運動組平均年齡為63.9±5.5歲、身高為159.1±9.4公分、體重為59.2±9.7公斤；控制組平均年齡為61.5±6.5 歲、身高為161.7±7.5公分、體重為62.9±9.0公斤。運動習慣組及環狀運動組進行每週3次，每次40分鐘為期12週的環狀運動，控制組以正常生活模式進行。將所得資料以多尺度熵進行分析，並以獨立樣本t檢定及單因子共變數分析來考驗運動習慣對高齡睜眼、閉眼終止步態及睜眼、閉眼靜態平衡之影響，以及經由環狀運動介入對高齡睜眼、閉眼終止步態及睜眼、閉眼靜態平衡之影響。結果：（一）運動習慣能提升高齡者睜眼以及閉眼站立0至5秒平衡穩定度(p<.05)。（二）運動習慣能提升高齡者睜眼以及閉眼站立5至60秒平衡穩定度 (p<.05)。（三）經由環狀運動介入能提升高齡者睜眼站立0至5秒平衡穩定度(p<.05)，但對閉眼站立0至5秒平衡穩定度則無顯著成效(p>.05)。（四）經由環狀運動介入能提升高齡者睜眼站立5至60秒平衡穩定度(p<.05)，但對閉眼站立5至60秒平衡穩定度則無顯著成效(p>.05)。結論：規律運動能提升高齡者睜、閉眼終止步態以及靜態平衡穩定度；環狀運動介入能提升高齡者睜眼終止步態以及睜眼靜態平衡穩定度，但對睜眼終止步態以及睜眼靜態平衡穩定度則無影響。

Purpose: The purpose of this study was to investigate the effects of circuit exercise balancing capability in elderly with multiscale entropy. Method: Fifty-five elderly 55 to 80 years old appearance of integrity and ability to walk alone were randomly assigned to the following three groups. Twenty elderly were in the exercise habits group (age=66.1±8.0yr, ht=159.8±7.0cm, wt=62.8±9.0kg), another twenty elderly were in the circuit exercise group (age=63.9±5.5yr, ht=159.1±9.4cm, wt=59.2±9.7kg), who attended the circuit exercise at 40 minutes per day, 3 days per week for 12 weeks. Fifteen elderly were in the control group (61.5±6.5yr, ht=161.7±7.5cm, wt=62.9±9.0kg). The data were analyzed by multiscale entropy, and assessed by t-test and one-way analysis of covariance (one-way ANCOVA). Result: 1. Exercise habits significantly improved the balancing capability of elderly both eyes open and eyes closed during 0-5 seconds (p<.05). 2. Exercise habits significantly improved the balancing capability of elderly both eyes open and eyes closed during 5-60 seconds (p<.05). 3. The circuit exercise intervention significantly improved the balancing capability of elderly of eyes open during 0-5 seconds (p<.05), but didn’t significantly influential on eyes closed (p>.05). 4. The circuit exercise intervention significantly improved the balancing capability of elderly of eyes open during 5-60 seconds (p<.05), but didn’t significantly influential on eyes closed (p>.05). Conclusion: This study indicated that Regular exercise can improve the elderly terminate gait and static balancing capability both eyes open and eyes closed. The circuit exercise intervention can improve the elderly terminate gait and static balancing capability of eyes open, but can’t improve the terminate gait and static balancing capability of eyes closed.
