Analysis and Prediction of Body Test Results Based on Improved Backpropagation Neural Network Algorithm

Figure 5

Shows the neural network trained according to the input of 1000 groups of sun running data and output of 1000 groups of endurance results. When randomly inputting 100 groups of students’ long-distance running data that has been trained, the BP neural network predicts the relationship between endurance results and actual values. It can be seen from the figure that the prediction accuracy of most points is high, except for some abnormal points.
