摘　　要：运用文献资料法对跳远运动员专项力量的概念、影响因素及训练进行分析探讨认为:起跳力量是跳远运动员的专项力量,它是通过“反射”的方式,将肌肉3种不同方式的工作紧密衔接,爆发性地完成收缩,弹性能量利用率是影响起跳力量大小的重要因素;而退让收缩时,肌肉被拉长的速度、长度及肌肉由离心收缩向向心收缩的转换速度,是影响弹性能量利用率的关键。在此基础上,对快速反应力量的训练提出建议。Through going over relative reference materials, this article analyzes the concept, the influence factors and its training of the specific force in long jump. Holding that takeoff force is the specific force of long jump, which break out according to stretch-shortening cycle by the way of reflecting, and the utility ratio of muscle bond energy is the important factor to the rapid reactive force, however ,the pre-stretched speed and length from its natural length and the interval from eccentric contraction to concentric contraction is the key to the utility ratio of muscle bound energy, and put out some suggestions on some problems existing its practice.
