Abstract: Track and field is a basic sport based on the coordination of limbs and joints, which reflects the internal relations among various sports and plays a very important role in the progress of competitive sports and the development of various sports. With the continuous development of sports and science and technology, the theory of track and field training is becoming more and more perfect. As for the huge and complex system of track and field training, it is difficult to make statistics and research without establishing a scientific and systematic nonlinear prediction model. In this paper, the evolution trend of track and field training is deeply studied and the model is constructed, which is dominated by gray prediction and mathematical statistics, and assisted by literature materials, in order to help relevant workers understand and apply relevant data and provide reference for track and field training.
