Neural mechanisms and post-exercise hypotension: The importance of experimental studies

Abstract

A single bout of exercise can decrease blood pressure level in hypertensive individuals and this phenomenon is known as post-exercise hypotension (PEH). PEH is clinically important and reduces blood pressure after physical exercise in hypertensive subjects. This reduction has been attributed to autonomic mechanisms, e.g., reduced peripheral sympathetic activity, adjustments in cardiac autonomic balance and baroreflex sensitivity. Besides, evidence has suggested that the central baroreflex pathway has an important role in the occurrence of PEH. Therefore, the aim of this study was to review the effects of physical exercise on areas of the central nervous system involved in the regulation of blood pressure.
