Blood Pressure Responses to Acute and Chronic Exercise Are Related in Prehypertension

Abstract

The magnitude of the acute BP-lowering with exercise may predict the extent of BP lowering after chronic training interventions in prehypertensive individuals.

Continuous and Accumulated Bouts of Cycling Matched by Intensity and Energy Expenditure Elicit Similar Acute Blood Pressure Reductions in Prehypertensive Men

“…Regular physical exercise, especially aerobic exercise, has therefore often been recommended for the prevention, treatment, and control of hypertension (36,41). Indeed, current evidence suggests that chronic reductions in blood pressure from engaging in long-term aerobic exercise programs are due largely to the summative effects of the blunted blood pressure response observed after single acute bouts of aerobic exercise (23). These blunted responses occur for several hours after exercise compared to the immediate pre-exercise period, or a non-exercise control day, and is a phenomenon known as postexercise hypotension (PEH) (37).…”

“…Recentemente, Liu et al 22 e Tibana et al 23 demonstraram redução crônica da PA após um programa de exercício físi-co, tanto em indivíduos pré-hipertensos 22 como em normotensos 23 . Além disso, os autores observaram que a redução crônica está associada com a magnitude da hipotensão pós-exercício.…”

Neural mechanismsand post-exercise hypotension: The importance of experimental studies

“…In table 1 are presented post-exercise autonomic responses assessed by different methods. Overall, there were reductions of muscle sympathetic nerve activity after aerobic exercise 10,11,52 , reduction of cardiac autonomic balance 14,53 , and increase of baroreflex sensitivity and heart rate variability 54 . Contrarily, other studies reported increased cardiac and vasomotor sympathetic modulation, decreased parasympathetic modulation and/or attenuation of baroreflex sensitivity 12,13,15,55 however, those studies used resistance exercise 13,15,55 or maximal aerobic exercise 12 .…”

“…Post-exercise hypotension [PEH] is a prolonged decrease in arterial blood pressure after a single bout of exercise 7 . The autonomic mechanisms attributed to PEH are welldocumented, such as reduced peripheral sympathetic activity 10,11 , modifications in the cardiac autonomic activity 12,13 and adjustments in the baroreflex sensitivity 14,15 . On the other hand, the central neural mechanisms have only recently been discovered and investigated.…”
