一、前言三级跳远运动是典型的速度一力量型项目，它是以速度为核心，以力量为基础的多级“跑跳型”运动。从三级跳远多级“跑跳型”技术特点知道，助跑速度损失，特别是水平速度的损失，是影响三级跳远成绩的关键。而作为无论是速度素质，还是腿部支撑负荷能力（力量素质）都 I. Introduction The triple jump exercise is a typical type of speed-power project. It is a multi-level “running jump-type” exercise based on speed and with strength as its foundation. From triple jump multi-level “running jump” technical characteristics know that the run-up speed loss, especially the horizontal speed loss is the key to the success of triple jump performance. As both the speed of quality, or leg support load capacity (strength of quality) are
