目的：探討優秀跆拳道選手旋踢不同踢擊位置對電子護具得分判定之影響。方法：以 20 位優秀大專 甲組擅長旋踢動作之跆拳道選手為受試者，並利用電子感應護具與計分系統進行量測。採用 SPSS 20.0 版處理，以重複量數單因子變異數 (α=.05) 進行統計分析，比較不同踢擊位置於電子護具力量感應 數值的差異及得分判定。結果：旋踢踢擊電子護具正面區塊顯著大於側面區塊力量感應數值 (p < .05)；在得分判定方面，踢擊護具正面有 82%的機率會絕對得分高於兩側位置。結論：Daedo 電子 護具正面位置感應數值及得分機率高於側面。採取旋踢攻擊鎖定正面位置，能提升有效的得分，而 在防守策略上應盡量避免曝露正面的有效感應區，防守多採取側面迎擊與手部防禦減少對手的有效 接觸。

Purpose: The purpose of this study is to analyze the resulting scores of different kicking positions on the Electronic Body Protector for the elite Taekwondo athletes. Methods: Twenty elite Taekwondo athletes who are good at Roundhouse Kick are selected. Each of them kicks on the Electronic Body Protector and the responding scores are recorded. The data is analyzed using SPSS 20.0. The one way ANOVA with repeated measures is used to test whether the scores on the different kicking position using the Electronic Body Protector will be different. The significance level is set to 0.05. Results: The inductive value of kicking on the front position are significantly greater than the inductive value kicking on the side positions. There are 82% chance which the scores of kicking on the front will be higher than 42. Conclusions: Daedo Electronic Body Protector is more sensitive on the front position than the side positions. The defense strategy is to avoid exposing the front side and use the flank attack and hand defense.
