Using BP neural network prediction model is established, with the methods of principal component analysis was carried out on the statistical data, obtained the four principal components. Based on the results of principal component analysis, the BP neural network model is established. With principal component analysis (pca) for the input, with the result of data processing to solve more than men's decathlon single movement data and the correlation of each single performance is stronger for shall not influence brought by the prediction accuracy of forecasting model, to improve the prediction precision of the prediction model, extending the application of the BP neural network prediction model.
