摘　　要：采用国产春风牌高速摄影机对九运会标枪男子前6名运动员的投掷步弧型助跑方式进行摄影,并运用影片解析,SPSS软件分析系统对数据进行分析处理,研究结果表明:“弧型助跑速度损失并不大;弧型助跑有利于满弓动作的形成;弧型助跑增大了双脚支持面积,提高了支撑的稳定性。The arc running-up modes for javelin-casting steps by the first six male athletes in javelin during the 9th National Games were photographed with a Spring Breeze Brand high-speed video camera made in China. After statistic analysis towards the data and film through SPSS system, it is concluded that arc running-up does not cause much loss in speed and it helps for the posing of full-bow action, increases the bearing space of feet and improves their stability.
