摘要
从生物力学的角度对短跑落地脚的动作进行分析,指出脚落地瞬间其绝对速度与人体整体运动方向一致,迄今未见例外.因而地面对落地脚的反作用力只能是阻力、制动力,进而对所谓落地脚积极下压扒地可以产生动力致使人体加速的错误认识进行澄清和纠正.
A biomechanical analysis on the landing motion of foot in sprint is made. It is pointed out that the absolute velocity of the foot at the moment of landing is in the same direction with the motion of mass-centre of sprinter′s body so that the reacting force of the ground on the foot is a resistance. A viewpoint that the positive motion of the landing foot picking the ground can generate driving to accelerate the sprinter is negated.
