踺子转体180°前手翻团身前空翻动作是近几年女子跳马比赛中新发展的一类动作，莫慧兰是我国最早完成此动作的运动员之一。运用生物力学研究方法，着重分析了她完成此动作的运动学特征，并提供了有关的技术参数，对于我国运动员掌握此类动作技术，并在此基础上开发新的难度系列动作具有重要的现实意义。
Shuttlecock swivel 180 ° before the hands turn the body forward flip action is a newly developed type of action in the women’s vault competition in recent years, Mo Huilan is one of the earliest athletes to complete this action. Biomechanics research methods, focusing on analysis of her kinematics to complete this action features, and provide the relevant technical parameters for our athletes to master such action techniques, and on this basis, the development of new series of difficult action has an important reality significance.
