摘要
本文使用三维测力台现场测量运动员在起跳过程中的动力学参数,用录像机现场记录,并计算出运动学参数,同时分析和讨论腾空高度及转动角速度等。
In this paper,immediately measure the dynamic parameter in the jnmp process of athlete with three dimenitonl dynamo- meter takle at the scene,calculate the kinematical parameter of ahtlete according to the recorol made by videocorder.It discusses and analyses the jump hight and the turning anagular veloeity of jump.
