To explore and develop a backpropagation neural network-based model for predicting and generating exercise prescriptions for improving cardiorespiratory fitness in older adults.
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) 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.
A neural network-based model for exercise prescription for cardiorespiratory fitness improvement in older adults is feasible and effective.
探索并开发一种基于反向传播神经网络的模型,用于预测和生成运动处方,以改善老年人的心肺适能。
该模型基于68项筛选研究的数据。此外,该模型在64名年龄在60 - 79岁的老年人中进行了验证。使用均方根误差(RMSE)、平均绝对误差(MAE)和决定系数(R)来评估模型的拟合和预测效果,并使用命中率来评估模型的预测准确性。
结果表明:(1)预测运动强度、时间和周期的平均误差率分别为7%±12、-5%±9%和 -7%±14%,表明估计值与预期结果高度一致。(2)在完成指定计划的61名受试者中,与运动前相比,心肺适能有显著改善。女性和男性受试者的改善范围分别为9.2 - 10%和8.9 - 15.8%。(3)此外,71%和94%的受试者(43/61)在正负一个标准差和正负1.96倍标准差范围内显示心肺功能有所改善。
一种基于神经网络的用于改善老年人心肺适能的运动处方模型是可行且有效的。
