| 采用三维高速摄像技术和运动生物力学原理，对后旋踢技术身体重心移动、动作所用时间、踝关节角度、膝关节角度和髋关节角度的运动学特征进行比较分析，得出结论：踢击腿在离地瞬间身体重心要快速向回旋方向移动；踢击腿膝关节最大程度弯曲，以缩短动作时间、加快踢击速度；踢击腿髋关节只有最大程度地弯曲，弯曲的膝关节才能快速展开；踢击腿的髋关节最大程度弯曲再打开时，踝关节能快速鞭打；支撑腿弯曲后在踢击腿踢出的瞬间，髋关节开始伸展，将对打击高度产生影响；踢击腿膝关节和髋关节最大程度弯曲时能增加击打力度 |

| Abstract: |
| In this research 3dimensional highspeed photography technology and sports biomechanics are applied to make a comparative analysis of kinematics features of gravity movement, time consumed by the movement, ankle joint movements, knee joint movements and hip joint movements. It is concluded that: when a kicking foot is off the ground, the gravity should move quickly towards the circle direction; in order to shorten the time of movements, knee joint of the kicking foot should bend to the maximal degree so as to speed up the kicking speed; Only when hip joints bend to the greatest extent can the bent knee joints stretch out quickly when having kicking，the kicking foot bends to the maximal degree while the hip joint bends the knee joint so as to speed up; the moment the supporting leg kicks out after the kicking foot bending；the hip joints begin to stretch out，which has impact on kicking height, when the knee joint and hip joint are bent to the maximal degree can increase the intensity of the impact |
