跳远踏跳技术与力学分析

The Analysis of Skills and Mechanics of Tread-jump in Long Jump

踏跳从力学角度可分为踏段和跳段。踏段是踏跳腿以最合理的着板动作和角度 ,使助跑速度损失率尽量减小 ;跳段是把握蹬伸时机 ,以强有力的蹬伸获取尽量大的垂直速度和合理的腾起角度。掌握完整的踏跳技术是提高跳远成绩的根本。

From the mechanics' angle, tread-jump can be divided into two steps-treading and jumping. Treading is the most reasonable action and angle of the jumping foot pressing the board for the purpose of reducing the rate of running speed as little as possible. Jumping is grasping the chance to get the quickest vertical speed and reasonable jumping angel with powerful pressing and stretching. To grasp the thorough skill of tread-jump is the thekey raising the mark of long jump.
