Postexercise Hypotension After Muscle Power Training Session in Older Adults With Hypertension

Abstract

The aim of the present study was to determine the acute effects of a muscle power training (PT) session on arterial blood pressure (BP) in older adults with hypertension. Thirteen participants (64 ± 4 years) with essential hypertension were randomly assigned to a PT session and control session without exercise. During PT, the participants performed three sets of eight repetitions at 50% of the one-repetition maximum tests. The concentric phase during each repetition was performed as fast as possible. The systolic BP (post-15 min: −1.7 ± 1.8 mmHg [p = .048; d = 0.22]; post-30 min: −3.6 ± 1.7 mmHg [p = .010; d = 0.48]; post-45 min: −3.3 ± 1.3 mmHg [p = .002; d = 0.42]; post-60 min: −3.9 ± 1.7 mmHg [p = .003; d = 0.49]) and diastolic BP (post-15 min: −1.5 ± 1.5 mmHg [p = .053; d = 0.20]; post-30 min: −2.2 ± 1.7 mmHg [p = .001; d = 0.29]; post-45 min: −2.0 ± 2.0 mmHg [p = .001; d = 0.27]; post-60 min: −2.0 ± 1.3 mmHg [p < .001; d = 0.26]) reductions were observed at all times after the PT session, compared with the preexercise and control session. PT is an effective strategy to acutely reduce BP in older patients with essential hypertension.

Effects of a single bout of power exercise training on ambulatory blood pressure in older adults with hypertension: A randomized controlled crossover study

“…No differences between the sessions were found for 24 h, daytime and nighttime systolic and mean BP. These findings partially confirm the results of two recent studies that found office BP reduction during 1 h after the power training session 23,24 and add new information related to the effects of power training on 24 h BP in older men and women with essential hypertension.…”

“…Office BP was lower after PT session than that obtained in Con, confirming the post-exercise hypotensive effect after PT session and the effectiveness of this alternative form of resistance exercise to acutely reduce BP. 24 However, exercise professionals should prescribe effective and proper resistance exercises not only to achieve maximal benefits but also to avoid exacerbated hemodynamic responses during exercise 40 that increases the risk of acute adverse events especially in patients at higher cardiovascular risks. 20 Slight increases in cardiac load as assessed by rate pressure products that occurred during the PT session were expected, and no adverse events occurred during the exercise session.…”

“…The number of repetitions per set greatly and adversely affects BP response during exercise when resistance training is performed to volitional exhaustion. [20][21][22] To the best of our knowledge, studies investigating an effect of a single bout of power exercise training (PT) on BP are scarce, and the available studies only assessed BP under office conditions, 23,24 and no data are available on the effects of power exercise training on ambulatory BP. Accordingly, the aim of the present study was to evaluate the effect of PT on office and 24 h blood pressure in older adults with hypertension.…”

Effect of High-velocity Resistance Exercise on 24-h Blood Pressure in Hypertensive Older Women

“…Despite the importance of power exercises to improve neuromuscular-and functional-related outcomes, little is known about the acute post-exercise effect of power exercises on BP in older adults, particularly those with hypertension. To the best of our knowledge, only three previous studies have investigated the acute effect of power exercises on BP in hypertensive older adults [10][11][12]. However, these studies assessed BP post-exercise during a very short-term period (i. e., ≤ 60 min) in a laboratory setting, which precludes the understanding of the clinical importance of PEH.…”

Sex Differences in Post-exercise Hypotension, Ambulatory Blood Pressure Variability, and Endothelial Function After a Power Training Session in Older Adults

“…Traditional resistance exercises and high-velocity resistance exercise (i.e., PT) are effective strategies to induce PEH under laboratory conditions (Casonatto et al, 2016;Coelho-Júnior et al, 2017;Domingues et al, 2020;Machado Filho et al, 2020). However, few data have demonstrated that this hypotensive effect is not sustained when BP is assessed throughout long periods and under usual conditions in patients with essential hypertension (Queiroz et al, 2015;Oliveira-Dantas et al, 2020;Schimitt et al, 2020).…”
