| 摘 要： | 背越式跳高“J”型助跑曲线并非越接近起跳点曲率越大,而是在最后四步的第一、第二、第四步起点处弯曲显著,第三步起点处衔接平缓,这和运动员在曲线段的再加速有关。

| Abstract: | The curvature of the J-type approaching curve for the bake style jump is not the greater, the closer to the bar the jumper. It is found that the curvatures at the first, the second and the fourth starting points of the last four steps are more marked, but flater atthe third one, It seems to be related reacceleratina along the curve, to athlete's |
