Abstract
The purpose of this study was to analyze the movements of the lower extremity joints during a taekwondo kick motion called 'Juchumseogi hu Apkkoaseogi yeopchagi', which was administered to players to improve their balance, stability, and range of motion for the prevention of injuries. Eight professional players and amateur players were recruited as the subjects. Kinematic data were collected by four real-time infrared cameras. The hip joint, knee joint, and ankle joint angles were measured using instruments. During the 'Juchumseogi hu Apkkoaseogi yeopchagi' kick motion, there were small and inconsistent effects on each joint. This study processed the data using the Windows SPSS Ver. 18.0 to get an independent t-test, with the setting, p< .05. Results indicated that hip joint, knee joint, and ankle joint angles were almost significantly different between professional and amateur player during 'Juchumseogi hu apgeule Apkkoaseogi' kick motion.
