普通高中女子三级跳远的课余训练

三级跳远技术结构是由一次助跑与三次起跳动作组成。由于助跑产生的水平速度会随着单足跳与跨步跳和跳跃的依次出现而逐渐递减。因此,在三级跳远中的三次起跳过程如何减少水平速度的损失和获得必要的垂直速度,成为完善三级跳远技术中需要解决的重要难题。而在普通高中的课余训练中又有诸多因素制约了训练的正常进行。根据所带三级跳远运动员吴丽娜(国家一级运动员)3年的课余训练,进行分析探研,供同行们商榷。

Discussion about the After-school Training of General Senior High Girl Students' Triple Jump

The actions of a run-up and three jumps are the components of the technical structure of triple jump. The horizontal velocity is losing gradually with the appearance of the single foot jump,the step jump and the taking-off. So decreasing the lose of the horizontal velocity and increasing the vertical velocity is a important problem to solve,to consummate the technical of the triple jump. There are lots of factors restricting the training in general senior high school also. Here's our analysis and study according to the three-year after-school training of triple jumper Wu Lina (the national level athletes) for discussion by colleagues.
