碩士 === 中國文化大學 === 運動教練研究所 === 87 === The study was using Peak Performance 2D Motion Analysis System and Force Load Sensor to analyze the kinematic parameters and the relative hitting force parameters of two kinds of Taekwondo Ax-kick. The results were as follows: 1. The bending knee ax-kick and the straight knee Ax-kick, their displacements of the body’s center of gravity were not obviously different. 2. The maximum velocity of the body’s center of gravity was indicated after the kicking leg taking off from the ground. Then it gradually slowed down. 3. The angular displacement of Knee joint of the bending knee Ax-kick was above the straight knee Ax-kick, but the angular displacement of Hip joint was not. 4. The bending knee ax-kick and the straight knee Ax-kick, their movement displacements was not obviously different 5. The moving time of the bending knee Ax-kick was shorter than the straight knee Ax-kick, and the moving velocity of the bending knee ax-kick was faster than the straight knee Ax- kick. 6.The hitting forces of the two kinds of Ax-kicks were not obviously different.
