掷铁饼技术的最后用力是整个技术过程的关键环节。用高速摄影与三维影片解析的方法对我国6名优秀女子铁饼运动员的投掷技术进行测试，并在部分参数上与国外选手对照。用最后用力技术中人体与器械质心的速度变化和器械质心高、低点出现时机等多项指标，揭示人体─器械系统的运动学规律及其特征，找出我国优秀女子铁饼选手技术上的优势与不足，并针对技术状况提出建议。 The last force of discus throwing technology is the key part of the whole technical process. The technique of throwing six elite female discus throwers in our country was tested with high-speed photography and three-dimensional video analysis method, and compared with foreign players in some parameters. With the end of the force in the human body and device speed changes in the center of mass and equipment, high centroid, low timing and other indicators to reveal the human ─ ─ instrument system kinematics rules and characteristics to find out the technical superiority of our elite female discus players And deficiencies, and recommendations for technical conditions.
