撑杆跳高握杆两手对撑杆的作用力的研究

A Study of the Forces Applied by the Two Hands on the Pole in Pole Vault

根据材料力学理论,利用测力—摄影同步采集的方法,在弹性材料电测技术的帮助下,计算出撑杆跳高运动员握杆两手对撑杆的作用力,发现了运动员的一些用力特点。在撑杆跳高技术的研究方法上作了进一步的探索。

By simultaneous use of the methods of dynamometry and photography,and with the help of the technology of electricmeasurement of the strength of elastic materials,the forces applied by the two hands on the pole in pole vault was calculaedin the light of material mechanics and some characteristic strength.The study constituted an attempt at exploring new waysfor examining pole vault techniques.
