The personalized training of elite athletes is the key to the breakthrough of Chinese track and field events in the Tokyo Olympic Games. The brilliance of Chinese women's throwing benefits from the closed-loop personalized training system. Training starts from the construction of accurate personalized technology and physical fitness model. This paper introduces the concept of champion model and puts forward a targeted technical training system based on the differentiation research of champion model. This paper mainly studies and analyzes some important technical parameters and achievements of elite female discus athletes aged 2018∼2021 by using the methods of Pearson, partial correlation and grey correlation analysis. We select from several technical parameters with significant differences, choose from several technical parameters that have significant difference, and calculate the correlation parameters and results. The results show that the influence degree of these technical parameters is as follows: torso angle of right foot touching the ground, discus release angle, discus release speed, shoulder and arm passing angle of left foot off the ground, discus moving distance of double support, center of mass moving distance of double support, and time of the second single support stage. This is different from our view that the hand speed is the most important, so the training of elite athletes should be more refined and specialized to promote the improvement of their performance. Through the application of technical diagnosis model in Chen Yang in a period of time, Chen Yang got her best result (65.14 m) in Chongqing Athletics Championship, which verified the success of the technical diagnosis model and application in this study.
精英运动员的个性化训练是中国田径项目在东京奥运会上取得突破的关键。中国女子投掷的辉煌得益于闭环个性化训练体系。训练从构建准确的个性化技术和体能模型开始。本文介绍了冠军模型的概念，并提出了基于冠军模型差异化研究的针对性技术训练体系。本文主要运用 Pearson、偏相关和灰色关联分析等方法，对 2018∼2021 年年龄的优秀女子铁饼运动员的一些重要技术参数和成绩进行了研究和分析。从具有显著差异的几个技术参数中进行选择，计算相关参数和结果。结果表明，这些技术参数的影响程度如下：右脚触地时的躯干角度、铁饼投掷角度、铁饼投掷速度、左脚离地时肩部和手臂的通过角度、双支撑阶段铁饼的移动距离、双支撑阶段质心的移动距离和第二单支撑阶段的时间。这与我们认为手速最重要的观点不同，因此，对精英运动员的训练应该更加精细和专业化，以促进他们成绩的提高。通过在一段时间内将技术诊断模型应用于陈扬，陈扬在重庆市田径锦标赛上取得了她的最好成绩（65.14 米），验证了本研究中技术诊断模型及其应用的成功。
