前言对运动技术作定量分析时,测定人体在运动过程中的总重心是不可少的。用人工计算周期过长,不能及时处理,无法对体育运动技术进行同期现场指导,纠正错误动作的效果不佳。用计算机处理,计算迅速而准确性高,反馈时间短,能及时为教练员、运动员提供一系列有用数据、并能直观地显示人体重心,绘制人体总重心或环节重心的运动轨迹图等等。总之能有利于及时发现问题、优化运动技术。
Introduction When quantitative analysis of sports techniques is performed, it is indispensable to determine the total center of gravity of the human body during exercise. The manual calculation period is too long to be handled in time, and it is impossible to conduct on-the-spot guidance on sports technology during the same period, and the effect of correcting wrong actions is poor. With computer processing, the calculation is rapid and accurate, and the feedback time is short. It can provide coaches and athletes with a series of useful data in a timely manner, and can intuitively display the person’s center of gravity, draw the body’s total center of gravity or link the center of gravity of the track and so on. In short, it can help discover problems and optimize sports skills in a timely manner.
