Abstract :
A stochastic sequential model is applied to heart-rate response during exercise. Heart-rate-need functions are found through steady-state analysis. Heart rates of two subjects are used to track the heart-rate-need functions in a cycle ergometer experiment in a manner represented by a first-order sequential model. Under conditions of increased physical or emotional stress, heart rates can track the heart-rate-need functions in a manner represented by a second-order sequential model. Because of similarities of transfer-function representations for heart rate and respiration, respiration can also be represented by a first-order sequential model.<>
