[Physical exertion tolerance and hemodynamic support of its various levels in patients with hypertension].

A study of 50 male patients with essential hypertension and 50 normal males showed hypertensive patients to have reduced exercise tolerance, as compared to normal subjects, its principal cause being the inadequate rise of systolic ABP during bicycle ergometry. In doing mild exercise (50 W), hypertensive patients showed an adequate hemodynamic response that was disrupted in medium-intensity exercise (100 W), and the hemodynamic support of heavy exercise (200 W) was inadequate.
