The purpose of this study was to investigate the kinematic variables of an effective attack and defensive motion dollyochagi motion, which is one of the most popular kicks during competition gyorugi so as to be able to provide scientific background during training. 1. There was statistically significant differences at the event E2 for the hip angle. 2. There was highly statistically significant differences at the event E2 for the knee angle. 3. There were no significant differences during all the phases for the ankle angle. 4. There were no significant differences during all the phases for the trunk angle. According to the results from above, even though the motion requires very complicated coordination, in general the hip, knee, ankle and trunk angle were similar for the attacking dollyochagi and the defensive dollyochagi. The most important variable for the effective performance of the dollyochagi is the flexion of the hip, knee and ankle at the kicking foot’s takeoff which will help enable a more powerful quicker kick which is needed during competition.
