女子撑竿跳高持竿助跑与起跳的速度特征

Velocity Characteristics Of Women's Pole-Vaulting In Both Approach Holding Pole And Jump

采用扫描拍摄和录像解析的方法,分析了女子撑竿跳高运动员持竿助跑与起跳的速度特征。测试结果表明:1)女子撑竿跳高的助跑速度还有很大的提高空间;2)女子撑竿跳高运动员最后两步助跑的速度是增加的,但有部分运动员从倒2步到倒1步的速度是减小的;3)女子撑竿跳高运动员起跳过程中水平方向速度损失过大,垂直方向速度增值过大。

By using the method of shoot and record, this paper analyzed the velocity characteristics of women's pole-vaulting in both approach holding pole and jump. The result shows: 1) there is still big space to improve their velocity of approach holding pole; 2) the approach velocity of the last two paces increased, however some subject's amplitude of velocity decreased; 3) both their horizontal velocity loss and vertical velocity increment were too much in the phase of jump.
