Abstract

The cardiovascular response to dynamic exercise is characterized by increases in blood pressure, myocardial contractility, and heart rate (Mitchell, 1990). In addition, cardiac output is redistributed such that blood flow is reduced in the renal and splanchnic circulations,while it is greatly increased to the heart and contracting skeletal muscles (Armstrong et al, 1987). Although central neural mechanisms (i.e. central command) and reflexes originating in working skeletal muscles are largely responsible for these alterations (Mitchell, 1990), hormones released during physical activity also may contribute to or modulate the cardiovascular response to dynamic exercise.
