在网球运动中控制身体平衡是技术得以正常发挥的重要前提。在运动中身体总是在寻求平衡来完成相应的技术动作,而头部姿势的改变往往是新的平衡的开始。 根据运动生理学状态反射的原理可知,一旦人体头的位置发生改变,相关的肌群张力会反射性地发生变化,使身体保持平衡,并且便于人体向着头部转动的方向进行移动。由此可见,头部的正确方位对完成正确的运动技能是非常重要的。人体在大脑皮质作用和调节下,对状态反射是可以控制的,所以有效地控制头部移动是创造良好平衡的先导。另外,必须明确的是头部的移动幅度和快慢是为了配合身体其他部 Controlling body balance in tennis is an important prerequisite for the proper functioning of the technology. In the sport, the body always seeks balance to complete the corresponding technical action, and the head posture change is often the beginning of a new balance. According to the principle of state reflection of exercise physiology, it is known that once the position of the human head changes, the related muscle group tension changes reflexively to keep the body in balance and to facilitate the movement of the human body in the direction of head rotation. From this it can be seen that the correct orientation of the head is very important for the correct motor skills. Under the action and regulation of the cerebral cortex, the human body can control the state reflex, so effectively controlling head movement is the guide to create a good balance. In addition, it must be clear that the head movement and speed is to fit the rest of the body
