On the prediction of the supercompensation phase by determining the parameters of the living functional system of the body

On the basis of the overdamped Duffing model, a technique for determining the key parameters of functional systems of the living body has been developed which characterizes its properties during recovery from standard physical load. As an example, the dynamics of restoration of pulse frequency is considered. The knowledge of these parameters allows one to predict the response of the living body to intensive external loads. This information can also be helpful for the optimization of the training process.
