摘要
在全国十运会期间对现役国家女子垒球队两名优秀投手的环绕式投球作现场三维定点拍摄和录像分析.实验结果表明女子垒球投手的整个投球动作连贯,投球的各项运动生物力学指标接近世界一流水平.其中吕伟的各项实验指标优于李琪,吕伟的投球技术已达到世界一流投手行列.
By the live video shooting and three dimensional kinematical analysis of the two outstanding active duty pitchers＇ circling throwing ball of the national woman＇s softball team during the tenth national games,we find that the action of throwing the ball is perfect coherence, and all the movement biomechanical indexes have reached the first level in the world. Between the two, Lu Wei, whose ball throwing level has reached the first class level in the world,is better than Li Qi.
