Abstract
An exercise apparatus including an exercise-load applying device which applies an exercise load to a person such as a patient, an exercise-load changing device which changes the exercise load applied to the person by the exercise-load applying device, a pulse-rate measuring device which successively measures a pulse rate of the person in synchronism with a heartbeat of the person, a blood-pressure measuring device which successively and non-invasively measures a blood pressure of the person in synchronism with the heartbeat of the person, a calculating device which successively calculates a product of the pulse rate and the blood pressure in synchronism with the heartbeat of the person, and a control device which controls the exercise-load changing device to change the exercise load applied to the person by the exercise-load applying device, so that the products successively calculated by the calculating device substantially coincide with a predetermined target value.
