掷铁饼是单手握持铁饼站在投掷圈后缘,经旋转后充分发挥全身的力量,以最快的出手速度和最适宜的出手角度,将铁饼从体侧后方经体侧向前掷出,并尽可能获得远度的投掷项目。这项运动属于田径项目中力量速度型的技术项目。它既需要最大的爆发力速度,更需要完整正确的技术动作。随着竞技体育的不断发展并为了适应竞赛规则的不断演变,人们对铁饼技术进行了不断的改进。从自由式、侧向转身、跳跃旋转、起跑式旋转、低腾空连贯旋转等多种技术形式,逐渐发展到今天被人们广泛采用的突出连贯加速、大动作半径和大用力幅度的背向旋转技术。与此同时,这些技术特征的变异 Throwing discus is a one-handed holding discus standing on the trailing edge of the throwing circle, fully exerting the power of the whole body after rotation, throwing out the discus from the rear of the body through the side of the body with the fastest shot speed and the most suitable angle of attack , And as far as possible get the throwing project. This sport belongs to the speed-type technical project of track and field. It requires both the maximum explosive speed, but also the need for complete and correct technical action. With the continuous development of competitive sports and in order to adapt to the ever-changing rules of the competition, discus techniques have been continuously improved. From the freestyle, turn around the side, jump to spin, start running rotation, continuous rotation and other forms of low vacancy and other forms of technology, and gradually developed today is widely used to highlight the coherent acceleration, large radius of motion and large reverse rotation . At the same time, variations of these technical characteristics
