短跑技术发展至今,在跑的周期动作结构上并没有根本性的变化,而只是围绕着步长、步频的相应关系,在大腿前摆和后蹬的参数上发生变化,使短跑技术更完善。针对短跑技术日益提高的过程,详细叙述大腿积极前摆对提高短跑速度的几点认识,以及对短跑训练的分析。 There is no fundamental change in the structure of the periodic movement of the sprint since the development of the sprint technique. Instead, the sprinting technique has been improved by changing the parameters of the front thigh and the rear pedal based on the corresponding relationship between the step length and the pitch frequency. . Aiming at the increasing process of sprint technology, this article describes in detail the understanding of improving the speed of sprint when the thighs are active and the analysis of sprint training.
