根据常识和生物力学基础,视觉评价技术可分成五个部分:1、有利地位;2、动作简易化;3、平衡和稳定;4、动作关系;5、动作幅度。有利地位.运功员和观察者的位置将决定在评价中什么能被观察到而什么不能。如果视觉评价技术的充分利用,应仔细选择有利地位。选择合适的观察距离 According to common sense and biomechanics, visual evaluation techniques can be divided into five parts: 1, favorable position; 2, simple action; 3, balance and stability; 4, the action relationship; The position of the warriors and observers will determine what can be observed and what can not be done in the assessment. If the full use of visual evaluation techniques, should be carefully chosen a favorable position. Select the appropriate observation distance
