體感太極拳運動應用於社區老人之初探

Kinect Tai-Chi Exercise for Community-dwelling Older People: A pilot Study

近年來，為增強參與動機，以體感互動式的科技逐漸應用於健康促進運動與復健領域，達到提升趣味性及運動效益。前人研究對太極拳的各種運動效益已多所結論，但太極拳的學習並非容易，故發展以太極拳為基礎之體感遊戲，隨時有影像指導及動作正確度的反饋，應較有利於老年人的運動學習和成就感。本研究旨在探索，體感太極拳運動應用於社區老人之可行性、運動強度、相當運動量及接受度。本研究為便利取樣，自社區招募五位老年自願者，試用體感太極拳運動六分鐘。於運動前後測量血壓、心跳、與運動自覺程度。運動過程中以心率錶測量運動時間的平均心跳率、最大心跳率與能量消耗。運動結束後以科技接受模式量表測量老人之接受度。結果顯示，運動前後的運動自覺程度有顯著差異，血壓心跳則無。運動強度為最大預測心跳率之63.6%（50.2~66.5%），其能量消耗為3.17（1.21~4.94）代謝當量，運動自覺程度為12（7~15），屬輕、中度運動。科技接受模式量表顯示，使用意願之面向為最高，其次為娛樂性。故體感太極拳的運動量適合老年人，並應考量主觀感受，未來可推廣至居家與社區。

Recently, the interactive video game technology has been enormously applied to health promotion and rehabilitation to enhance motivation and participation. Evidence of Tai chi exercise on muscle strength/endurance, balance, fall prevention and many physiological systems has been reported widely in previous studies. However, it is not an easily-learning exercise. Therefore, modified Tai chis exercise via embodied interactive games maybe beneficial for the elderly due to the immediate guidance and feedbacks on movement accuracy. The purpose of this pilot study is to investigate the feasibility, exercise intensity, energy consumption and acceptance of Kinect Tai-chi exercise program for the community-dwelling elderly. A convenience sample of five elders, aged more than 60, was recruited from a community. They practiced Kinect Tai-Chi exercise level 1A for six minutes individually. Blood pressure, resting heart rate and rate of perceived exertion (RPE) were assessed before and after exercise. During exercise, average heart rate, maximal heart rate and energy expenditure were also measured by a heart rate monitor (Polar FT7). A questionnaire of technology acceptance model (TAM) was also assessed after exercise. In addition to descriptive statistics, Wilcoxon Signed-Rank Test was applied to analyze the pre-post exercise differences of BP, HR and RPE. Results showed only RPE scale was significantly higher after exercise, but not others. The average exercise intensity was 63.6 % (range 50.2%~66.5%) predicted maximal heart rate, energy expenditure was 3.17 (1.21~4.94) metabolic equivalents, and RPE scale was 12 (7~15). In the TAM questionnaire, the highest score was the dimension of intention to use, followed by enjoyment. Kinect Tai-Chi exercise provides a light to- moderate intensity and is considered fun, useful and suitable by the elderly. Perceived physical exertion should be considered during exercise. The interactive video games could be an alternative choice of exercise mode at home and in the community for the elderly in the future.
