“…The studies in older adults are scarce, and there is a lack of studies in active hypertensive individuals. In addition, controversial results have been described regarding BP response depending on the intensity of the exercise 7,8 or physical fitness status of the subjects (trained or untrained), as some studies showed no differences 9 and others showed that untrained subjects present a greater BP decrease than trained subjects 10 . Therefore, this study aims to compare the acute effects of two aerobic exercise intensities (low and moderate) on post‐exercise BP in adults with high‐normal BP/essential grade I hypertension and regular exercise participation.…”

The global burden of arterial hypertension was projected to rise from 918 million adults in 2000 to 1.56 billion in 2025. 1 Hypertension is a major, modifiable risk factor for serious health conditions, such as heart failure, and cardiovascular and cerebrovascular acute events. 2 Regular physical exercise has been widely recognized as an important strategy to control blood pressure (BP) in individuals with hypertension. 3,4 The reduction in BP observed after a single session of exercise, that is post-exercise hypotension, showed a strong positive correlation with the chronic reduction in BP observed after 8 weeks of exercise training 5 ; suggesting that the acute decrease in BP may be linked to long-term adaptations to exercise. 6 The studies in older adults are scarce, and there is a lack of studies in active hypertensive individuals. In addition, controversial results have been described regarding BP response depending on the intensity of the exercise 7,8 or physical fitness status of the subjects (trained or untrained), as some studies showed no differences 9 and others showed that untrained subjects present a greater BP decrease than trained subjects. 10 Therefore, this study aims to compare the acute effects of two aerobic exercise intensities (low and moderate) on post-exercise BP in adults with high-normal BP/essential grade I hypertension and regular exercise participation. 2 | ME THODS 2.1 | Study design This is a cross-over, repeated-measures study. Each participant completed two randomly assigned experiments (aerobic exercise at 30% and 60% of the heart rate reserve (HRres). The order of the experiments was randomized using a sealed, opaque, envelope. BP was measured before and after the acute experiments, and at every hour until 3 hours post-exercise. Both experiments were conducted at the

“…We chose to use this protocol in order to accommodate the IH bouts in between the HYP bouts. Also, we do not think that this affected the results since both continuous and intermittent types of aerobic exercise have been shown to induce PEH and improve sleep ( Kredlow et al, 2015 ; Pimenta et al, 2019 ).…”

No Decrease in Blood Pressure After an Acute Bout of Intermittent Hyperpnea and Hypoxia in Prehypertensive Elderly

Prevalence of hypertension, subjective sleep complaints and snoring increases with age. Worse sleep and snoring, in turn, are independent risk factors to develop hypertension. Both respiratory muscle training (RMT) and intermittent hypoxia (IH) are suggested to have positive effects on these physiological and behavioral variables. This study therefore aimed to test the acute effects of a single bout of RMT, with and without IH, on resting blood pressure (BP) and sleep. Fourteen prehypertensive elderly performed a 60-min session of (a) intermittent voluntary normocapnic hyperpnea (HYP) alone, (b) HYP in combination with IH (HYP&IH) and (c) a sham intervention in randomized order. BP, hemodynamics, heart rate variability (HRV), cardiac baroreflex sensitivity (BRS) and pulse wave velocity (PWV) were assessed before and 15, 30 and 45 min after each intervention. Variables of sleep were assessed with actigraphy, pulse oximetry and with questionnaires during and after the night following each intervention. Neither HYP nor HYP&IH resulted in a decrease in BP. Repeated measures ANOVA revealed no significant interaction effect for systolic BP ( p = 0.090), diastolic BP ( p = 0.151), HRV parameters, BRS and PWV (all p > 0.095). Fragmentation index was lower after both HYP (−6.5 units) and HYP&IH (−8.4 units) compared to sham, p (ANOVA) = 0.046, although pairwise comparisons reveal no significant differences. There were no other significant effects for the remaining sleep variables. We conclude that one bout of intermittent hyperpnea, alone or in combination with IH, is not effective in lowering blood pressure or improving sleep in prehypertensive elderly.

“…11 Studies have shown that the magnitude of PEH can be related both to the intensity reached during the exercise session, 10,11,39 and to the exercise volume. 11,40 In the present meta-analysis, most of the included studies ( ~ 66%; n = 8) [29][30][31][32]34,[36][37][38] equalized the volume, and / or average intensity, and / or total energy expenditure of IE with CE sessions, which can facilitate the understanding of the impact of the exercise nature (interval vs. continuous) and intensity of stimuli on the PEH magnitude. This aspect is important because studies show that when volume and/ or mean intensity are equalized, PEH is similar between IE and CE.…”

Background: Continuous aerobic exercise (CE) is one of the main non-pharmacological recommendations for hypertension prevention and treatment. CE is safe and effective to reduce blood pressure chronically, as well as in the first few hours after its performance, a phenomenon known as post-exercise hypotension (PEH). Interval exercise (IE) also results in PEH. Objective: This systematic review and meta-analysis sought to compare the magnitude of PEH between CE and IE in adults. Methods: A systematic review of studies published in journals indexed in the PubMed, Web of Knowledge, Scopus and CENTRAL databases was performed until March 2020, which compared the magnitude of PEH between CE and IE. PEH was defined as between 45-60 minutes post-exercise. The differences between groups on blood pressure were analyzed using the random effects model. Data were reported as weighted mean difference (WMD) and 95% confidence interval (CI). A p-value <0.05 was considered statistically significant. The TESTEX scale (0-15) was used to verify the methodological quality of the studies. Results: The IE showed a higher magnitude of PEH on systolic blood pressure (WMD:-2.93 mmHg [95% CI:-4.96,-0.90], p = 0.005, I2 = 50%) and diastolic blood pressure (WMD:-1,73 mmHg [IC95%: 2,94,-0,51], p= 0.005, I 2 = 0%) when compared to CE (12 studies, 196 participants). The scores of the studies on the TEXTEX scale varied from 10 to 11 points. Conclusions: The IE resulted in a higher magnitude of PEH when compared to CE between 45 and 60 minutes postexercise. The absence of adverse event data during IE and CE in the studies prevents comparisons of the safety of these strategies.
