速度是身体素质的一个方面,它指人体进行快速运动的能力,即在单位时间内迅速完成某一动作,或通过某一距离的能力。体育运动中,速度有重要意义。速度发展的水平对运动成绩有很大的影响。动作的速度取决于一系列生理和生化的因素。现已查明,速度、特别是动作频率极高的速度,取决于神经过程的灵活性.从生物化学观点看,速度素质取决于肌肉中三磷酸腺苷的含量,以及在神经冲动影响下其分解的速度,甚至还取决于三磷酸腺苷再合成的速度。旨在发展速度的工作,导致形成大量的氧债,为偿付氧债要用几十分钟的时间。一个人所能发挥的最高速度,不仅取 Speed ​​is one of the aspects of physical fitness. It refers to the ability of the human body to perform rapid exercise, that is, the ability to accomplish an action quickly or through a certain distance within a unit of time. In sports, speed is important. The level of speed development has a great impact on athletic performance. The speed of the action depends on a number of physiological and biochemical factors. It has been determined that speed, and particularly the rate of action, is extremely high, and depends on the flexibility of the neural process. From a biochemical point of view, the speed quality depends on the content of adenosine triphosphate in the muscle and its rate of disintegration under the influence of nerve impulses , And even depend on the rate of adenosine triphosphate resynthesis. Work aimed at speeding up has led to the formation of large amounts of oxygen debt, which takes dozens of minutes to pay for the debt. A person can play the highest speed, not only to take
