Cardiac ultrasound techniques have provided an abundance of empirical information regarding normal circulatory responses to dynamic exercise. These data are consistent with a schema by which alterations in peripheral resistance, effected by arteriolar dilatation, facilitate blood flow to exercising muscle and match these responses to increasing metabolic demand. In this model, cardiac responses are governed by quantity of systemic venous return, matched by increases in heart rate to maintain a… CONTINUE READING
