The kinematic variables of Apchagi in Taekwondo were analized. The Apchagi variables compared in two situations ;1) When the subjects performed the tickings with target.2) When the subjects performed the tickings without target.Three Taekwondon athletes who hare practiced for more than seven yearn were selected among Yonsei University Taekwondo team as SubjectsThe hip, knee, ankle and metatarsal phalangat joints of the subjects were marked with white dots.The kicking performances were filmed using Bolex high speed camera with film speed of 64 frames / sec.The velocity, acceleration, angular velocity and angular acceleration If the necessary joints and segments were calculated through kinematic analysis procedure Which developed in Yonsei University.The results reported in graph form to provie basic information for the skills and compared the kinematic variables of the two kicking, with target which simulate competitive situation and without target which is used for training, to provide information fur training.The following conclusions could draw from the results.The patterns of the kinematic variables of the kicking with target and without target were similar, however the patterns in relate with the target area were which suggest prectie kicking should perform with soft target, different as if the whole pattern shifted backward and showed low values at the target area in kicking without target. The angular velocity of the thigh decreased as the velocity of the shank increased and showed whipping motion which is most efficient mechanical method to increase velocity of the distal segment.
