THE EFFECT OF KARATE STANCE ON ATTACK-TIME: PART II - REVERSE PUNCH

Abstract

This report presents the second part of an empirical study of the effect of stance on attack-time during a karate movement. A t-test and linear regression method are used to analyze the data collected from 24 elite karate competitors in simulated reverse punches. The results show the 7:3 stance exhibiting a slightly faster movement than that of the 5:5 stance. However, the mean difference is not significant. A two-way ANOVA is also adopted to analyze the data from Part I and Part II to identify the factors important to the attack-time. The results show the stance is the only factor significant to the attack-time. Since jab and reverse punch have their advantages in a contest. All the karate competitors should practice the two frontal-attack techniques in 7:3 stance to optimize the performance.
