在铁饼投掷中,必须抓住解决主要技术环节,方能取得较好成绩。投掷过程中的主要技术是在适当角度下加大投掷的初速和器械的飞行初速度。为使器械早己获得一定的加速度,运动员要做好预摆和最后用力。我在几年来的教学和训练的过程中认识到,在投掷器械的重量固定不变的情况下,要获得较大的初速度,加大作用于器械的力量和铁饼离手后的飞速度是十分重要的。下面谈谈个人几点初步体会,不当之处请批判指正。

In the discus throwing, we must seize the major technical aspects, in order to achieve better results. The main technique in the process of throwing is to increase the initial speed of throwing and the initial flying speed of the instrument at an appropriate angle. In order for the device to get a certain acceleration already, the athlete should make the pre-swing and the last force. In the course of teaching and training over the years, I realized that in the case of a fixed weight of throwing equipment, to obtain a greater initial velocity, increase the force acting on the instrument and the flying velocity after the discus leaves the hand Very important. Here to talk about personal initial experience, improper please critique.
