在短跑教学中,一些教师强调跑动中的伸膝、伸髋及下肢的蹬伸能力,旨在增大步幅,提高短跑速度,却往往忽视了摆动效果和整体运动环节的协调配合,易造成身体重心在垂直方向的波动加大,降低整体水平运动的效果,影响水平运动速度的发挥和高速跑中的放松技术。现代短跑技术应视为以髋为轴的高速摆动——平动运动,这是短跑运动和短跑技术的本质特征。本人在教学中强调髋关
In sprint teaching, some teachers emphasized the ability to stretch knees, extend hips, and stretch the lower extremities in order to increase the pace and increase the speed of sprinting while ignoring the coordination of the swing effect and the overall movement. Causes the body’s center of gravity to fluctuate in the vertical direction, reducing the overall horizontal movement effect, affecting the speed of the horizontal movement and relaxation techniques in high-speed running. Modern sprint technology should be considered as a hip-shaft high-speed swing - translational motion, which is an essential feature of sprinting and sprinting techniques. I emphasize hip clearance in teaching
