摘要

目的：探討斜切式旋踢影響感應數值得分表現的下肢關節動作技術特徵為何。方法：以19名跆拳道優秀選手於實驗室以30°斜切攻擊角度踢擊電子護具。透過三維分析系統（Motion Analysis Corp., Santa Rosa）搜集踢擊動作下肢關節運動學特徵，以皮爾森積差相關分析，來瞭解斜切式旋踢下肢關節線性速度、角度和角速度參數與得分感應數值之相關（α= .05）。結果：末端踝關節與足部的線性速度與得分感應數值達顯著正相關（p ＜ 0.05）。骨盆、髖關節、膝關節和踝關節的最大角度、角速度峰值與踢擊感應數值之間未達顯著相關（p ＞ 0.05）。結論：本研究發現以斜切式旋踢攻擊，末端踝關節與足部的速度是影響電子護具感應數值得分表現的重要因素。

Purposes: Explore roundhouse kicks at various attack angles and investigate the skill characteristics of lower limb joint movements that affect the induction value score. Methods: Nineteen outstanding taekwondo players performed kicking at 30° by targeting an electronic protector. A three-dimensional analysis system (Motion Analysis Corp., Santa Rosa) was utilized to collect the characteristics of lower limb joint kinematics during kicking movement. Pearson's product correlation analysis was adopted to establish how the linear velocity, angle, and angular velocity of the lower limb joint while kicking at an angle of 30° correlated with the score generated by a sensor (α= .05). Results: The linear velocities of the ankle joint and foot were significantly and positively correlated with the induction value score (p ＜ 0.05). By contrast, the maximum angles and angular velocities of the pelvis, hip joint, knee joint and ankle joint did not significantly correlate with the induction value from the kick (p ＞ 0.05). Conclusion: This study discovered that when roundhouse kicks delivered in an angle of 30°, the velocities of the ankle joint and the foot are critical to the induction value score.
