摘要

本研究目的是探討後踢動作之支撐腳在攻擊期中的重要性。七名男子大專甲組跆拳道選手（年齡：21.0±2.0歲、身高：180.4±4.4公分、體重；69.1±26.1公斤）為本實驗之受試者。並以左腳為攻擊腳來踢 擊後踢。本實驗使用之硬軟體包括三軸加速規（CXL50LP3）、兩台高速攝影機（Redleke）、Kwon 3D動作分析軟體與Biovision生物訊號擷取系統。兩台Redlek高速攝影機拍攝（60Hz）受試者踢擊動作，並用Kwon 3D動作分析軟體得到運動學之參數；三軸加速規是固定在沙袋上（20kg），力量為沙袋質量與加速度之積。使用Biovision系統與DasyLab 6.0軟體來計錄加速規之值與計算踢擊力量之值。研究結果顯示，於後踢攻擊期，攻擊腳膝關節最大角速度，出現在踢擊至沙袋的瞬間。支撐腳於後踢攻擊期不同的表現中，研究發現：支撐腳在攻擊期會向目標滑動踢擊，此種型態在現今比賽屬於攻擊型。另一型態於支撐腳在攻擊期會向上跳動踢擊，在現今比賽屬於反擊型。由獨立樣本t考驗，考驗出攻擊型支撐腳移動距離顯著大於反擊型支撐腳（p＜.05）。且後踢支撐腳膝關節之角速度和支撐腳移動距離與力量，皆達顯著相關（p＜.05）。可知支撐腳膝關節之角速度和踢擊力量也有密切之關係。而支撐腳在攻擊期之動作表現，影響到後踢之攻擊型態，進而影響後踢之運動表現。故後踢支撐腳佔一重要之地位。

The purpose of this study was to investigate the importance of support leg for back kick during the attack phase. Seven male taekowndo athletes(age: 21.0 ± 2.0 year old, height: 180.4 ± 4.4 cm, weight: 69.1 ± 26.1 kg) performed the back kick. The left leg was the attack leg, and right leg was the support leg. The equipment and devices included an accelerometer (CXL50LP3), Biovsion system, two high-speed cameras (Redleke) and Kwon 3D motion system. The back kick motion was collected by two Redleke cameras (60Hz). Kinematics data proceed by Kwon 3D motion system. The accelerometer was fixed on a kicking bag (20kg). Biovision system and DasyLab software were used to recode acceleration and calculate the force value. The results indicated that the peak of knee angular velocity for the attack leg appear in the hitting to the kicking bag. The support leg has two fighting patterns. One is attacking pattern which the support leg slid during attack phase. The other is counterattack pattern which the support leg jumped during the attack phase. The movement distance of attacking pattern is significant greater than that of counterattack pattern. There was significant positive correlation among the angular velocity, force and movement distance. According to the above revealed that the angular velocity of knee for support leg relate with force closely. The study shows the support leg influence the taekwondo fighting pattern and performance play the important role on taekwondo back kick movement.
