Abstract
A method of estimating exercise capacity of a subject is disclosed. The method uses output radiofrequency signals transmitted to the subject during exercise and input radiofrequency signals received from the subject during exercise. The method comprises: determining a phase shift of the input radiofrequency signals relative to the output radiofrequency signals; calculating cardiac output based on the phase shift; and using the cardiac output for estimating the exercise capacity of the subject.
