目的：設計開發低成本、能監測羽球步法移動、具備即時回饋功能，並可提供數據以做為監測與應用，進而有效提升訓練效益的運動視覺反應動作訓練系統。方法：邀請國中羽球選手 10 名 (9 男1女)，平均身高162.2 ± 4.9 公分、平均體重52.7 ± 7.4 公斤，以本研究研發的羽球運動步法與反應訓練系統進行維期3 周、每周3 次、共計9 次以米字型步法為主的訓練。接受訓練前與9 次訓練結束後皆進行米字型的視覺反應時間、整體動作時間與T 字型敏捷動作時間測試，再經由相依樣本t 檢定訓練效果與訓練器系統耐用功能測試。結果：本訓練系統可連續穩定長時間執行訓練與檢測，且檢測功能具良好的信效度 (ICC = 0.95, 0.96)；訓練後的視覺反應時間 (t = 4.09, p < .003*) 與敏捷動作時間 (t = 5.13, p < .001*) 皆達顯著進步。結論：本訓練系統具有輔助訓練、監控、檢測、紀錄與低成本的特性，可模擬比賽情境並準確紀錄整體動作、反應時間，進行介入訓練時可有效提升選手反應與敏捷能力，能具體有效地增進教練與選手訓練成果。

Purposes: To determine the effectiveness of a low-cost automated visual reaction training system that seeks to improve an athlete’s agility by providing real-time feedback and assessment of his or her footwork and providing data for further analysis. Methods: Participants consisted of badminton athletes from middle school (9 males, 1 female), with an average height and weight of 162.2 ± 4.9cm and 52.7 ± 7.4kg. Participants utilized the specially designed footwork and reaction training systems to train for 3 times a week for 3 weeks, total up to 9 training sessions. Participants used multi-directional shuffle drills as a basis of the training, and were assessed on their directional visual reaction times, overall action and agility timings, which were then used for comparison in an attempt to test the effectiveness and functionality of the product. Results: The training system was able to perform and monitor over continuous periods of time, while providing accurate and reliable evaluation abilities (ICC = 0.95, 0.96). Regarding training effectiveness, participants proved to have improved visual reaction times (t = 4.09, p < .003*) and agility action times (t = 5.13, p < .001*). Conclusions: The training system had proved to be able to assist with training, monitoring, analyzing and recording at a low cost. It was able to accurately track action and reaction timings, as well as simulate an official badminton match. Implementation of this system can effectively elevate the athlete’s reaction and agility abilities by enhancing both coaches and trainees training standard.
