田径速度力量性项目快速反应力量及其训练

The Rapid Reactive Force and Its Training in Speed-force Events of Track and Field

运用文献资料法对快速反应力量的概念、影响因素及训练进行分析探讨后认为:快速反应力量对田径速度力量项目的专项成绩产生重要影响,而弹性能量的利用率是影响快速反应力量的重要因素。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方法提出合理建议。

Through going over relative reference materials, this article analyzes the concept ,the influence factors and its training. Holding that the rapid reactive force is important factors for speed-- force events of track and field, 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.
