摘　　要：“跳起转体90°～180°直体后空翻转体720°”动作是近几年来女子跳马比赛中新发展的一类动作，运用运动生物力学的研究方法，着重分析杨亚红（目前我国惟一能完成该动作的运动员）完成该动作的运动学特征，并找出她的优势和不足。研究结果表明：杨亚红的助跑速度快，第2腾空转体角速度快，空中姿态保持较好，但第2腾空高度还不够。Handspring with 90 ～ 180ordm-layout back double twists is newly developed movement in woman vaulting horse competition in recent years. YANG Ya-hong is the only one who can complete this movement in China. With the method of sport biomechanics,this paper particularly analyzes the kinematical character of her completion on this movement ,find out her advantage and disadvantage. The result shows that YANG Ya-hong＇s running up is fast, the angle speed of handspring in the second flight is swift and the pose in the air is excellent ,but the height of handspring in her second flight is not enough.
