先期性研究：複雜工作的協調性探討

Preliminary Study: Investigation of Coordination under Complicated Work

本研究欲藉由無線感測裝置分析不同跳躍任務的協調性能力差異。方法：本實驗以12名健康男性大專生，於小腿外側配戴自製無線加速規並給予視覺影像節拍器及聽覺節拍聲，蒐集單純跳躍與給予雙重任務（拍手+跳躍）之下肢加速度數據，以Matlab R2008a軟體進行資料處理。實驗結果以SPSS 18.0統計軟體 進行獨立樣本單因子變異數分析（one-way ANOVA)，並進行事後比較，比較受 試者在固定節拍內做節奏性跳躍動作時其時間變化情形。結果：不同跳躍情境達顯著性的差異水準(F= 3.398, p<.05)，而在無拍手慣用腳跳躍組的組內變異最小。結論：由此可知使用慣用腳跳躍的節奏控制能力最佳，而視覺上的刺激在本研究中可能為影響跳躍節奏控制的主要因素。

The purpose of this study was to measure the different jumping tasks by using wireless sensor technology to investigate the motor coordination. Methods: The research was collecting the experiment data when jumping with multiple tasks via sensors with wireless transmitter device which was fitted in the lateral leg on twelve healthy male college students. The data analyzed by computer program developed on our own. Results: The different jumping situations were reached significantly in differences levels (F= 3.398, p<.05). In the case of using the dominant leg jump, the resulting CV value was significantly smallest among the three cases. Conclusion: Using dominant leg jump’s ability to control the rhythm can get best performance in this study. And visual stimulation may be the main factors controlling the rhythm jump.
