Introduction: To explore and develop a backpropagation neural network-based model for predicting and generating exercise prescriptions for improving cardiorespiratory fitness in older adults.Methods: The model is based on data from 68 screened studies. In addition, the model was validated with 64 older adults aged 60-79 years. The root mean square error (RMSE), mean absolute error (MAE) and coefficient of determination (R 2 ) were used to evaluate the fitting and prediction effects of the model, and the hit rate was used to evaluate the prediction accuracy of the model.The results showed that (1) The mean error ratios for predicting exercise intensity, time and period were 7% ± 12%, -5% ± 9% and -7% ± 14%, respectively, indicating that the estimates were in good agreement with the expected results. (2) Of the 61 subjects who completed the assigned program, cardiorespiratory fitness improved significantly compared with pre-exercise. Improvements ranged from 9.2%-10% and 8.9%-15.8% for female and male subjects. (3) In addition, 71% and 94% of subjects (43/61) showed cardiorespiratory improvement within plus or minus one standard deviation and plus or minus 1.96 times standard deviation.Discussion: A neural network-based model for exercise prescription for cardiorespiratory fitness improvement in older adults is feasible and effective.
