摘　　要：运用运动生物力学手段对后撤步技术进行了研究,并对后撤步技术阶段进行了时相划分,对后摆阶段、蹬地后撤阶段、腾空阶段和支撑缓冲阶段进行了运动学特征的分析.结果显示:后摆阶段是整个后撤步动作的开始,蹬地阶段膝关节的伸展程度影响右脚离地时的速度,腾空阶段身体的下肢关节逐渐伸展,支撑缓冲阶段的身体姿势影响着整个动作的连贯性.The research of the step back skill is analyzed by means of biomechanics, and the time phase division is also made to the process of step back. The analysis of kinematics characteristic is made to baekswing stage, stomp and recession stage, flight stage and supporting buffer stage. The backswing stage is the beginning of the whole step back action, the knee＇s stretching rate have an effect on the speed of the right foot leaving from the ground during the stomp stage, during the flight stage, the lower limbs of the body joints gradually extend, support buffer phase of body position affects the entire action consistency.
