投掷运动员,由于与田径重器械发生关系,在他们的训练中,通常用大部分时间来发展力量。现在,专家们普遍认为,最近几年来投掷成绩的进步,首先取决于运动员很好的力量训练程度。但,铅球运动员不能简单地发展力量。在这个项目中,获得速度力量,即在一瞬间所表现出来的力量具有特殊的意义。要知道,推铅球重要的不仅是具有巨大的力量,而且需要在一瞬间运用这种力量。这是田径投掷理论的基本原理之一。可见,必须注意到投掷运动员的动作速度。“运动员的动作速度愈快,就愈能在极短的时间里,为使器械产生加速度而动员自己的最大力 Throwing athletes, due to their association with track-and-field equipment, often spend most of their time developing strength in their training. Now, experts generally agree that progress in throwing grades in recent years depends first and foremost on the athlete’s good strength training. However, shot putters can not simply develop their strength. In this project, it is of special significance to obtain the power of speed, that is, the power shown in a flash. You know, it’s not just great power to shoot shots, but you need to use that power for an instant. This is one of the basic principles of track and field throwing theory. Visible, must pay attention to throwing athletes movement speed. "The faster athletes move, the more they can in a very short period of time, in order to make the acceleration of equipment to mobilize their greatest strength
