根据投掷技术原理推算:合理运用助跑的作用投掷标枪比原地投枪所增加的远度,男子是25—30米,女子是15—20米。这里且不去谈如果助跑技术掌握的特别好,能否突破这个数字的问题,仅就这个数字来看,助跑对标枪成绩的影响也是相当可观的。然而,在平时投掷标枪技术的教学训练中经常遇到这种情况:学生在上步掷枪或慢跑短程助跑掷枪时,最后用力完成的比较好,投的也比较远,但快速全程掷枪时情况就不然
Calculated according to the principle of throwing technology: the proper use of the role of runner throwing javelin throwing gun in situ than the increase in the distance, the man is 25-30 meters, the woman is 15-20 meters. Here and not to mention If the runway technology to master the particularly good, can break through the figure of this figure, only the runner on the javelin impact is considerable. However, this is often encountered in the teaching and training of throwing a javelin at normal times: when the student throws a gun or jog the short-range runner and throws the gun at the end, the last force is better and the cast is relatively far, but a fast full throw gun When the situation is not
