Abstract:
A dynamic model of the heart rate response to
treadmill walking exercise is presented. The model is a feedback
interconnected system; the subsystem in the forward path
represents the neural response to exercise, while the subsystem
in the feedback path describes the peripheral local response.
The parameters of the model were estimated from 5 healthy
adult male subjects, each undertaking 3 sets of walking exercise
at different speeds. Simulated responses from the model closely
match the experimental data both in the exercise and the
recovery phases. The model will be useful in explaining the
cardiovascular response to exercise and in the design of exercise
protocols for individuals.
