THE KINETIC ANALYSIS OF THE TAEKWONDO AXE KICK

The purpose of this study was to analyze the kinetics of taekwondo axe kick. Twenty junior high school level taekwondo athletes served as subjects, and their mean age, height, weight and training experience were 17.1 ± 1 years, 168.8 ± 5.8 cm, 59.9 ± 6.7 kg and 5.8 ± 1.6 years respectively. Two Kistler force plates and multifunctional record instruments were used to measure kinetic parameters in each phase of the axe-kick motion. The conclusions described as following: 1. the time to peak anterior-posterior ground reaction force of kicking leg prior to the time to peak vertical force. 2.the peak vertical ground reaction force and impulse of support leg were 1.79 times of body weight and 88.1 N-s during leg-lift phase, and 0.86 times of body weight and 64.9 N-s during legaxe phase. 3. It’s suggested that during the training should emphasize to decrease the response time in order to reduce the total time
