摘　　要：目的:揭示跳马前手翻直体前空翻转体540°动作运动学规律和技术特点,对进一步改进和发展此类难度动作提供了理论依据和技术参数。方法:通过ARIELAPASMultipleScream系统解析参加体操冠军赛杭州站的男子跳马决赛录像,采集相关数据进行分析比较。结果:运动员需加快助跑速度,以较大的速度上板;踏板时,减小膝关节角度,提供蹬伸所需条件;缩短第一腾空时间,积极主动撑马,为做较大背弓需保持适宜髋膝角度;推手短促有力,延长第2腾空的时间。Objective, open out the kinematical rule and technical feature of horse vaulting Hand- spring followed salto forward stretched with 11/2 twist, to provide more theoretics gist and technique parameter for ameliorate and develop this difficulty agcy. Investigate method parse the mankind horse vaulting playdown kinescope of gymnastics championship in Hangzhou by system ARIEL APAS Multiple Scream, then gather correlation date to analyze and compare. Result the athlete need to increase run-up speed to get high speed to foot contact; when foot contact, minish the angle of knee joint, provide condition for take off; shorten the time of preflight, initiative vaulting over the buck, keep coax-knee angle in order to make biggish arched body ,hand release bfiefiless and pithiness, prolong the time of second flight.
