一、基本要点链球运动员投掷成绩和其它投掷项目一样,是由器械出手的速度,高度,角度和空中飞行时空气的阻力所决定的。出手速度: 链球由静止状态开始,通过对链球施加力,在一定时间内产生了速度(牛顿第二定律)。运动员对链球施加力,是从握点或把手通过钢丝传递链球的球端的。 First, the basic points Hammer throwing achievements and other throwing items, as the speed, height, angle shot by the equipment and air resistance in the air when the decision. Shot speed: Hammer from the static state, by exerting force on the hammer, in a certain period of time produced speed (Newton’s second law). The athlete exerts a force on the hammer which transfers the hammer from the grip or handle through the wire.
