The Trend of Performance Changes in Youth Swimming Competitions in Zhejiang Province 2013-2023 and the Comparative Analysis of Two Performance Prediction Models for Performance Prediction
This article uses mathematical statistics and predictive analysis to analyze the results of the"Spring Welco-ming Cup"Zhejiang Youth Swimming Championships from 2013 to 2023.To explore the development and changes in the overall level of youth swimming from 2013 to 2023 by integrating the competition results from 2013 to 2022,the grey theory GM(1,1)prediction model and BP neural network prediction model are used to predict the championship results and the average scores of the top eight in 2023.The predicted values are fitted and compared with the meas-ured values of the 2023 competition,Using root mean square error(RMSE)and mean absolute percentage error(MAPE)to evaluate the predictive ability of the two models,exploring more effective performance prediction meth-ods and providing a theoretical reference for future preparation for important competitions.
