空手道迴旋踢正面抬腳與側面抬腳之運動學比較研究

本研究目的在於從運動學、人體動力學與解剖學的角度，比較探討空手道迴旋踢正面抬腳與側面抬腳兩種不同踢法的特點、優劣與原理。以台北市立體育學院空手道代表隊10名選手（男5名，女5名）作為施測對象，平均年齡19.28±1.43歲，平均身高169.80±6.03公分，平均體重64.1±6.85公斤，平均空手道側面抬腳迴旋踢訓練5.41±1.01年，平均空手道正面抬腳迴旋踢訓練4.02±0.36年。Peak高速攝影機，120／秒的拍攝速度，進行二度空間運動學比較。影片資料經Peak Performance分析系統及SPSS統計學電腦軟體分析後，研究結果如下：一、正面抬腳迴旋踢攻擊腿有較快的攻擊時間和平均速度，其平均值分別為0.31±0.05秒和6.75±0.48公尺／秒，而側面抬腳迴旋踢為0.41±0.06秒與5.63±0.54公尺／秒，兩者均達顯著差異。二、正抬腳迴旋踢有較佳的攻擊效果，其攻擊腿擊中踢靶的瞬間速度為8.67±0.92公尺／秒，側面抬腳迴旋踢僅為6.22±1.01公尺／秒，兩者均達顯著差異。三、正面抬腳迴旋踢比側面抬腳迴旋踢合理、優越，主要表現在運動幅度大，動作靈活易完成。正面抬腳迴旋踢踢出動作所產生的力量和速度都優於側面抬腳迴旋踢，且其抬腳時身體正面表面面積也小於側面抬腳迴旋踢（被對方擊中的可能性較小），分別為1.58±0.15平方公尺與1.70±0.17平方公尺，兩者均達顯著差異。

The purpose of this study was to discuss the positive and flank to lift knee in karate round kick from kinematic, kinesiology, and anatomy. The subjects were tested by karate athletes of Taipei Physical Education College (male 5, female 5), mean age 19.2 ± 1.43, mean ht. 169.80 ± 6.03, mean wt. 64.12 ± 6.85, mean of the flank to lift knee round kick in training years 5.41 ± 1.04, mean of the positive side to life knee round kick training years 4.02 ± 0.36. The date were analyzed with Peak Performance and SPSS. The result of this study show that: 1. There are significant in attacking time and mean velocity between the positive side to lift knee round kick (0.31 ± 0.5sec and 6.75 ± 0.48m/sec) and flank to lift knee round kick (0.41 ± 0.06 and 5.63 ± 0.54m/sec). The positive side to lift knee is better than flank to lift knee in karate round kick. 2. The instantaneous speed of attacking target in positive side to lift knee round kick (8.68 + 0.92m/sec) is better than from flank to lift knee round kick (6.22 ± 1.01m.sec). 3. The positive side to lift knee round kick is suitable and advantageous because of motion extent and motion flexible. To be attacking of body area, the positive side to lift knee round kick (1.58 ± 0.5m) is smaller from flank side to lift knee round kick (1.70 ± 0.17m2).
