Abstract

A model of the heart rate regulation during physical load and recovery has been developed. The model contains four parameters with the following physiological meanings: Heart rate increment related to the load of 1 watt, a load which can be coped with by vagal inhibition, a time constant of the vagal component and a time constant of the slower complex neurohumoral sympathetic component. All these parameters were estimated uniquely with relatively small reliability intervals for a group of 15 healthy men. The results are useful practically for the evaluation of the physical efficiency of individuals and whole groups of healthy subjects.
