The purpose of this study was to analyze toe kinematic variables of Jigeochagi in Taekwondo with three dimensional analysis technique and show the kinematic characteristics of it. The subjects of the experiment were Taekwondo players who have been attending in Yong-in university(YIU), and Jigeochagi is their favorite technique, the kicking form was filmed on 16mm video camera(30f/s). Kinematic variables were temporal, posture and angular velocity. The mean values were obtained and used as basic factors for examining characteristics of Jigeochagi in Taekwondo. The results of this analysis were as follows. 1. The total time elapsed(TE) of Jigeochagi were 1.45, 1.56 sec. 1ph was fastest in performance showing then 2ph, 3ph. 2. In performing of Jigeochagi, the ankle, knee angle of supporting foot and the ankle, knee angle of attacking foot flexed to MKA then extened to IMP 3. The ankle, knee, hip angular velocities of attacking foot showed negative value to TO and then positive value to MKA and then showed negative value to IMP.
