Postexercise Hypotension

Abstract

A single bout of exercise can lead to a postexercise decrease in blood pressure in hypertensive individuals, called postexercise hypotension. Compelling evidence suggests that the central baroreflex pathway plays a crucial role in the development of postexercise hypotension. This review focuses on the exercise-induced changes in brainstem nuclei involved in blood pressure regulation.

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

“…Within a practical perspective, whether or not a correlation between blood pressure and sympathovagal balance is observed after exercise might be a result of exercise volume -in other words, the compensatory response related to acute blood pressure lowering and shift in cardiac autonomic balance might also be associated with exercise volume. It has been advocated that exacerbated hemodynamic responses after exercise may be influenced by the amount of muscle work, which would increase the exercise pressor reflex (ergoreflex) through afferent stimuli from muscle ergoreceptors (mechanoreceptors and metaboreceptors) (8,16,26). The increased muscle afferent signaling would contribute to a higher sympathetic activity during exercise and to a consequent 'resetting' of the arterial baroreflex during the postexercise period, reducing sympathetic outflow and lowering blood pressure (15,16).…”

“…It is known that blood pressure is determined by the relationship between cardiac output (Q) and systemic vascular resistance (SVR), cardiac (central) or vascular (peripheral) mechanisms that reflect changes in central regulation (8), leading to attenuation of the blood pressure response in the postexercise recovery.…”

Caracterização da resposta hipotensora pós-exercício

“…Assim, por um lado, a realização de atividade e/ou exercício físico é importante no tratamento não farmacológico para a redução da PA. Por outro, ainda não está definido o melhor tipo de exercício, sendo o aeróbio o mais indicado, segundo os artigos pesquisados [22][23][24][25][26][27] .…”

Aerobic Exercise and Eucalyptus Globulus: Cardio-affective effects on recovery and stress

“…Thus, it is believed that the eucalyptus essential oil has minimized stressor stimulus within the hypothalamic paraventricular region leading to a possible reduction on sympathetic stimulus to the cardiovascular system. In addition, the associated physical exercise could enhance such responses, via baroreceptor reset, reaching the nucleus of the solitary tract [11,12]. However, further studies are needed in order to ensure the abovementioned hypotheses regarding the central modulation of the vascular response in induced stress.…”

“…eucalyptus essential oil inhalation suggest a central action regarding the interaction between the 1.8-cineole component and the paraventricular region of the hypothalamus, which is directly related to autonomic regulation [11]. Kc & Dick [2] highlight that paraventricular nucleus neurons present stress signalizers, which modulate GABA neurotransmitters increasing sympathetic nervous activity.…”
