女子箭步式上挺和下蹲式上挺的动力学比较研究

The Study of Comparing Female Split Jerk with Drop Jerk In Dynamics

箭步式上挺和下蹲式上挺是上挺的两种方式 ,国内对这两种上挺方式的争议较大 ,本文从动力学特征方面对箭步挺和下蹲挺进行比较研究 ,为教练员和运动员认识和寻找适合自己的上挺方式提供理论依据 .在研究中采用录象和三维测力台同步测试的方法进行研究 ,发现下蹲挺需要的上挺发力峰值小 .

Split jerk and drop jerk are different in jerk kind. People at home have different opinions about this two kinds of jerk. This study is to compare the split jerk with the drop jerk in the characteristics of dynamics, and offer the theoretical basis to athletes and coaches to think and look for the clean & jerk mode that suits themselves. The study selects the testing method that video synchronizes camera with force platform. The results indicate that maximal jerk force of drop jerk is smaller.
