“…We showed a significant decrease in SBP, DBP, and mean arterial pressure (MAP) to the end of the 70-min monitoring period, with no trend towards returning to baseline values when preceded by prior exercise. 38 In our study, the decrement in SBP averaged 16 mm Hg, and was as much as 23 mm Hg below control levels when preceded by a bout of exercise. It may be that activities of daily living following exercise potentiate the reductions in blood pressure.…”

“…There have been a handful of studies that have examined the time course of PEH using ambulatory monitoring. 15,34,38,41,44,56,61 We are aware of seven that have truly attempted to examine whether the hypotension is preserved during subsequent mild exercise or routine daily activities. Results from these studies are contradictory and may be confounded by the fact that post exercise activity was not controlled in all but one study, and that most investigators used intermittent auscultatory methods to determine blood pressure.…”

Post exercise hypotension (PEH) is a phenomenon of a prolonged decrease in resting blood pressure in the minutes and hours following acute exercise. Knowledge of PEH is potentially useful in designing first line strategies against hypertension as well as allowing a further understanding of blood pressure regulation in both Keywords: blood pressure; vascular; cardiac; opioids; exercise Blood pressure responses during exerciseDuring dynamic exercise, cardiac output increases dramatically to ensure adequate perfusion to the working musculature. This increase is achieved by a withdrawal of parasympathetic tone (causing an increased heart rate and contractility), an increase in sympathetic activity (directly and indirectly increasing heart rate and contractility) and pronounced vasoconstriction of the venous vasculature (causing a greater venous return and therefore stroke volume). In parallel, the need for increased blood flow and oxygen delivery to the exercising muscle is achieved through regional vasodilation of those arterioles supplying blood to the exercising tissue in combination with a vasoconstriction of arterioles, which perfuse non-essential tissues. Although the mechanism of vasodilation at the onset of exercise is not fully understood, many compounds (eg, potassium, adenosine, nitric oxide, etc) have been implicated in the exercise induced changes. Contraction of the active muscle mass also assists in returning blood towards the heart. This 'muscle pump' effect further increases venous return and stroke volume.Increased cardiac output and vasoconstriction in non-exercising vascular beds increases systolic blood pressure (SBP), but the significant vasodilation at the exercising muscle beds helps to buffer this increase and results in a minimal rise in diastolic blood pressure (DBP).

The acute post-exercise response of blood pressure varies with time of day

et al. 2008

The reactivity of ambulatory blood pressure following a given change in everyday physical activities is highest in the morning. Whether the acute response of blood pressure following a controlled bout of steady-state exercise is influenced by time of day is examined in this study. After 45 min of supine rest, 12 male normotensives completed 30 min of cycling at 70% VO(2peak) which began at either 0800 or 1600 hours. Arterial blood pressure, cardiac output, total peripheral resistance, cutaneous blood flow and temperature were determined before, and up to 90 min after, exercise. Mean +/- SE arterial pressure, averaged over the acute (20-min) period, reduced by 7 +/- 2 mmHg following exercise at 1600 hours but increased by 3 +/- 3 mmHg following exercise at 0800 hours (P = 0.03). Total peripheral resistance fell by 4.2 +/- 0.8 mmHg l(-1) min(-1) after exercise at 1600 hour, but increased slightly by 0.1 +/- 0.5 mmHg l(-1) min(-1) after morning exercise (P = 0.02). We conclude that the acutely hypotensive effects following 30 min of steady state exercise are less marked in the morning, probably because the exercise-mediated decrease in peripheral resistance is not as apparent at this time of day.
