速度训练在田径运动许多项目中都已成为极其重要的内容，特别是400米之内各距离跑的运动员，提高绝对速度水平是提高运动成绩的关键。10秒左右的快速运动能力和爆发力，是绝对速度的基础，这在很大程度上依赖于人体磷酸原系统的供能能力，而训练手段对能量供应系统刺激的?.. Speed ​​training has become an extremely important element in many track and field events, especially for athletes within a distance of 400 meters. Increasing the absolute speed level is the key to improving athletic performance. The rapid exercise and explosive power of about 10 seconds is the basis for absolute speed, which is largely dependent on the ability of the human body’s phosphate system to supply energy, while the training methods stimulate the energy supply system.
