摘要

羽球米字步法常被使用於敏捷能力訓練與檢測，爭取在最短的時間內完成，不過在不同計時儀器的使用上容易造成時間差異而影響成績表現，因此本研究目的欲利用無線加速規、影像分析與傳統手按碼表量測羽球米字步敏捷性測驗，探討計時差異情形。方法：實驗徵求6位大專男性羽球愛好者，利用數位錄影機、手按碼表與無線加速規收集並分析6次米字步敏捷性測試之完成時間。實驗結果以SPSS 20.0進行組內相關係數（The intra-class correlation, ICC）考驗所測資料之信賴度，並計算出每次跳躍的時間平均值與標準差，再進一步求得變異係數（Coefficient of Variation, CV）。結果：三種方法皆能分析米字步測試的完成時間（ICC＞.70）。結論：本研究中驗證以穿戴是無線感測裝置所量測之數據有極高的信賴度，未來可以建議使用在類似人體運動分析上。

Badminton split steps test often used in agility training and testing, and to be completed within the shortest possible time. But, using different timing equipment easily caused timing differences. Purpose: The aim of this study was to investigate whether the customized wireless accelerometer can achieve the same timing results with the traditional ways. Methods: Six male college badminton lovers joined the split steps test. Using digital video recorder, stopwatch and wireless accelerometer collected and analyzed 6 times of split steps tests completion time. The data were analyzed by the intra-class correlation (ICC) test with SPSS 20.0 statistical software. Results: Three methods all can be used to analyze the split steps tests completion time (ICC＞.70). Conclusion: This study verified the wearable wireless sensing device has a high reliability to measure the test. In the future, this wearable wireless sensing device can be recommended for use on similar human motion analysis.
