銀髮族功能性體適能運動對其跨越障礙物之影響

預防老年人跌倒是現今重要的課題，但過去在老年人的運動介入多為單一方向的訓練。研究目的：本研究以介入銀髮族功能性體適能運動三個月，比較老年人在功能性體適能檢測上的差異及跨越障礙物生物力學參數上的差異。研究方法：使用8台高速攝影機收集11位老年人跨越三種不同高度障礙物的動作資料，收集27位老年人體適能檢測資料。以二因子變異數分析障礙物高度與運動介入前後對跨越障礙物能力之影響，以相依樣本t檢定分析老年人功能性體適能檢測的差異。研究結果：在運動介入後領導腳腳尖與障礙物的垂直距離變大，骨盆中心點最小位移速度變慢。在體適能檢測方面，所有的檢測項目皆有顯著改善。結論：銀髮族功能性體適能運動介入後，老年人在體適能檢測結果皆有顯著變好，進而影響其跨越障礙物時的動作策略，顯示銀髮族功能性體適能運動對老年人的體適能及預防跌倒的發生是有幫助的。

Purpose： The purpose of this study was to compare the differences of biomechanical parameters in obstacle crossing and the parameters in physical fitness tests before and after a 3-month elderly functional fitness exercise intervention. Methods： Eleven and 27 subjects participated in obstacle crossing and functional fitness tests, respectively. VICON motion analysis system with eight cameras was used to record kinematic data during negotiating obstacles in three different heights. The functional fitness test was also performed. Two-way ANOVA with repeated measure was used to evaluate the effects of obstacle height and exercise intervention. Paired-t test was used to compare the fitness change following exercise intervention. Results： The leading foot toe clearance significantly increased and the minimum velocity of the pelvis center significantly decreased following exercise intervention. All fitness tests showed significant improvement compared to pre-intervention. Conclusion： The findings of this study suggested that the older people had substantial improvement in physical fitness following a 3-month elderly functional fitness exercise program and the strategy of obstacle crossing has been modified. The functional fitness exercise is beneficial for the prevention of the fall in the elderly.
