  • Title: Cardiovascular responses to dynamic exercise.
    Author: Hossack KF.
    Journal: Cardiol Clin; 1987 May; 5(2):147-56. PubMed ID: 3555794.
    Abstract:
    Dynamic exercise results in a marked increase in oxygen consumption. This increase is accomplished by a significant increase in heart rate and peripheral oxygen extraction and, to a lesser extent, by an increase in stroke volume. There is a small increase in mean systemic and pulmonary artery pressures and marked decrease in systemic and pulmonary resistances with exercise. The result of changes in focal vasomotor tone is that a greater percentage of the cardiac output is directed to the working muscles.
