The purpose of this study is to investigate the relationship between the support leg and attack pattern for back kick during the attack phase. Seven male Taekowndo athletes - age: 21.0 ± 2.0 year old, height: 180.4 ± 4.4 cm, weight: 69.1 ± 26.1kg performed the back kick. The back kick motion was collected by two Redlekecameras (60Hz). Kinematics data was analyzed by KWON 3D motion system. The accelerometer was fixed on a kicking bag 20kg . Biovision system was used to recode acceleration value. The results indicated that the peak angular velocity of knee in the attack leg appear during the hitting to the kicking bag. The fighting type can divided attacking and counterattack pattern from support leg. In terms of moving distance of support leg, attacking pattern is significant loner than counterattack pattern. There was significant positive correlation among the angular velocity, force and movement distance.The study shows the support leg motion will influence the Taekwondo attack pattern and performance.
