Purpose The purpose of this study is to investigate the comparison of peak resultant force in taekwondo body dollyeochagi in accordance with Jejariditgi existence and the position of kicking leg. Methods Twelve students who majored taekwondo participated in this experiment. They have a forth dan(degree) black belt in taekwondo. The peak resultant force was measured 12 times(2 jejariditgi existence × 2 position of kicking leg × 3 times). Two-way ANOVA with repeated measures was used to analyze the data. Results There was significant difference in interaction effect of peak resultant force in taekwondo in accordance with jejariditgi existence and the position of kicking leg. And there was significant difference in main effect of peak resultant force in taekwondo in accordance with jejariditgi existence and the position kicking leg. Higher peak resultant force was shown in body dollyeochagi with jeariditgi as compared with non jejariditgi. And higher peak resultant force was shown in rear kicking leg as compared with front kicking leg. Conclusions The results show that jejariditgi is a factor affecting the peak resultant force. Comparison of peak resultant force in taekwondo body dollyeochagi in accordance with jejariditgi existence and the position of kicking leg will provide strategies for coaches and athletes to perform improved taekwondo dollyeochagi.
