“…These values range from 2 to 17 and from 2 to 7 mm Hg for systolic and diastolic BP, respectively, in aerobic exercises [4,32]. For resistance exercises, most studies prove a reduction of 2-13 mm Hg for systolic BP and 2-7.9 mm Hg for diastolic BP [23,[32][33][34][35][36]. On the basis of the PEH values found in this study, the effectiveness and possibility are evident of applying FT in order to promote PEH in borderline hypertensive patients.…”

Purpose. The potential of functional training (FT) to improve health is evident. However, regarding post-exercise hypotension (PEH) in older adults, there are few data. The study aimed to determine the cardiometabolic demand imposed by an FT session and evaluate PEH, comparing it with exercise sessions with aerobic and resistance exercises in physically active practitioners. Methods. Fourteen young (23.3 ± 2 years) and 15 older (68 ± 4 years) adults underwent a control session and FT session randomly determined. Blood pressure, heart rate, and double product were recorded at rest, during exercise, and in every 10 minutes over 60 minutes of recovery. Additionally, we measured the rate of perceived exertion (RPE). Results. The FT protocol promoted systolic PEH in both groups in the last half of recovery, reaching a reduction of 10.4 ± 4.9 mm Hg in young and 13.4 ± 3.8 mm Hg in older adults (p < 0.05). No differences were observed between the groups (p > 0.05). There were no differences between the groups with reference to RPE at any time (p > 0.05). Conclusions. A single FT session is able to promote PEH in normotensive young and borderline hypertensive older adults but without changing the RPE in comparison over the time, owing to a great similarity of FT practices in the groups.

“…Muller et al (24) had participants perform isometric handgrip and found that older adults experience lower rate-pressure product and coronary blood flow velocity responses. Unlike isometric exercise, the blood pressure responses to dynamic resistance exercise are attenuated in middle-aged compared with young adult males (16). Likewise, rhythmic handgrip during a period of experimentally lowered blood flow results in an attenuated MSNA and blood pressure response with aging (18).…”

“…For example, Markel et al (18) reported attenuated sympathetic and blood pressure responses in older adults during blood flow restricted rhythmic exercise. Additionally, Kawano et al (16) found blunted increases in blood pressure in middle-aged men during acute resistance exercise, a task that activates group III/IV sensory fibers. It is unclear what role the venous distension reflex plays in the age related differences in sympathetic and cardiovascular responses to exercise.…”

Wenner MM, Farquhar WB. Peripheral venous distension elicits a blood pressure raising reflex in young and middle-aged adults. Am J Physiol Regul Integr Comp Physiol 310: R1128 -R1133, 2016. First published April 6, 2016 doi:10.1152/ajpregu.00438.2015.-Distension of peripheral veins in humans elicits a pressor and sympathoexcitatory response that is mediated through group III/IV skeletal muscle afferents. There is some evidence that autonomic reflexes mediated by these sensory fibers are blunted with increasing age, yet to date the venous distension reflex has only been studied in young adults. Therefore, we tested the hypothesis that the venous distension reflex would be attenuated in middle-aged compared with young adults. Nineteen young (14 men/5 women, 25 Ϯ 1 yr) and 13 middle-aged (9 men/4 women, 50 Ϯ 2 yr) healthy normotensive participants underwent venous distension via saline infusion through a retrograde intravenous catheter in an antecubital vein during limb occlusion. Beat-by-beat blood pressure, muscle sympathetic nerve activity (MSNA), and model flow-derived cardiac output (Q), and total peripheral resistance (TPR) were recorded throughout the trial. Mean arterial pressure (MAP) increased during the venous distension in both young (baseline 83 Ϯ 2, peak 94 Ϯ 3 mmHg; P Ͻ 0.05) and middle-aged adults (baseline 88 Ϯ 2, peak 103 Ϯ 3 mmHg; P Ͻ 0.05). MSNA also increased in both groups [young: baseline 886 Ϯ 143, peak 1,961 Ϯ 242 arbitrary units (AU)/min; middle-aged: baseline 1,164 Ϯ 225, peak 2,515 Ϯ 404 AU/min; both P Ͻ 0.05]. TPR (P Ͻ 0.001), but not Q (P ϭ 0.76), increased during the trial. However, the observed increases in blood pressure, MSNA, and TPR were similar between young and middle-aged adults. Additionally, no correlation was found between age and the response to venous distension (all P Ͼ 0.05). These findings suggest that peripheral venous distension elicits a pressor and sympathetic response in middle-aged adults similar to the response observed in young adults.age; sympathetic; MSNA VENOUS DISTENSION ELICITS a pressor and sympathoexcitatory response that is mediated by group III/IV sensory fibers. The venous distension reflex can respond to distension of small vessels located within the skeletal muscle caused by increased blood flow (11), as occurs during skeletal muscle contraction. Haouzi et al. (12) found that in anesthetized cats, distension of the small veins by mechanical or pharmacological means resulted in activation of both group III and group IV skeletal muscle afferent nerves, with a preference for the latter. Similarly, Yamauchi et al. (33) reported that injections of Ringer's solution into the left femoral vein of decerebrate rats during circulatory occlusion caused a pressor response that was volume dependent.While the data in humans are limited to only a few studies (2-6), there is evidence that peripheral venous distension elicits sympathoexcitation and increases blood pressure. For example, Cui et al. (5) found that saline infusion into an antecubital vein of an occ...

Abstract-The present study aimed to determine the effect of the intensity of aerobic and resistance exercise on the 24h BP response in normotensive women. Twenty-four women (aged 33 ± 9 years) performed five experimental sessions in randomized order: CON -no exercise; AE50 -50% of heart rate reserve (HRR); AE70 -70% of HRR; RE40 -40% of 1repetition maximum (RM) and RE70 -70% of 1RM. Systolic and diastolic BP and HR measurements were measured during 24h post-exercise at the participant's workplace. The AE50, AE70 and RE40 sessions led to the greatest and longest-lasting effects on the SBP, which persisted for up to 24h. For the DBP, the experimental sessions led to similar results; post exercise hypotension was observed until 7h post-exercise, with the exception of the AE70 session, which produced effects that persisted for 24h. Results shows that both aerobic and resistance exercise performed during the morning can decrease the mean BP above the baseline lasting 24 hours during a normal daily work. The aerobic exercise performed around 50% of HRR can better regulate both systolic and diastolic BP in this population.Keywords: post exercise hypotension, resistance exercise, aerobic exercise, womenResumo-"Efeitos das intensidades de exercícios aeróbios e resistidos nas respostas de pressão arterial durante 24 horas em mulheres normotensas." O objetivo do presente estudo foi determinar os efeitos das intensidades de exercícios aeróbio e resistido nas respostas da pressão arterial de 24h em mulheres normotensas. Vinte e quatro mulheres (33 ± 9 anos) participarem de cinco sessões experimentais em ordem randomizada: CONsem exercício; AE50 -50% da freqüência cardíaca de reserva (FCR); AE70 -70% da FCR; RE40 -40% de 1 repetição máxima (RM) e RE70 -70% da 1RM. As medidas das pressões sistólica (PAS) e diastólica (PAD) e a FC foram realizadas durante 24h após o exercício no local de trabalho. As sessões AE50, AE70 e RE40 demonstraram maiores e mais duradores efeitos na PAS, e permaneceram ate às 24h. Já na PAD houve respostas similares, com hipotensão até 7 horas após o exercício. Com exceção da sessão AE70, onde perdurou por 24h. Os resultados demonstraram que ambos os exercícios aeróbicos e resistidos realizados pela manha pode reduzir a PA abaixo da linha base e perdurar por 24h durante um dia normal de trabalho. O exercício aeróbio realizado a 50% da FCR pode proporcionar melhores resultados na regulação de ambas PAS e PAD nessa população.Palavras-chaves: hipotensão pós exercício, exercício resistido, exercício aeróbio, mulheresResumen-"Los efectos de las intensidades del ejercicio aeróbico y resistido en las respuestas de la presión arterial de 24 horas en mujeres normo tensas."
