OBJECTIVE: The aim of this study was to describe blood pressure responses during resistance exercise in hypertensive subjects and to determine whether an exercise protocol alters these responses. INTRODUCTION: Resistance exercise has been recommended as a complement for aerobic exercise for hypertensive patients. However, blood pressure changes during this kind of exercise have been poorly investigated in hypertensives, despite multiple studies of normotensives demonstrating significant increases in blood pressure. METHODS: Ten hypertensive and ten normotensive subjects performed, in random order, two different exercise protocols, composed by three sets of the knee extension exercise conducted to exhaustion: 40% of the 1-repetition maximum (1RM) with a 45-s rest between sets, and 80% of 1RM with a 90-s rest between sets. Radial intra-arterial blood pressure was measured before and throughout each protocol. RESULTS: Compared with normotensives, hypertensives displayed greater increases in systolic BP during exercise at 80% (+80±3 vs. +62±2 mmHg, P<0.05) and at 40% of 1RM (+75±3 vs. +67±3 mmHg, P<0.05). In both exercise protocols, systolic blood pressure returned to baseline during the rest periods between sets in the normotensives; however, in the hypertensives, BP remained slightly elevated at 40% of 1RM. During rest periods, diastolic blood pressure returned to baseline in hypertensives and dropped below baseline in normotensives. CONCLUSION: Resistance exercise increased systolic blood pressure considerably more in hypertensives than in normotensives, and this increase was greater when lower-intensity exercise was performed to the point of exhaustion.
Effect of different resistance exercise methods on post-exercise blood pressure
2008
Pr re es ss su ur re e ABSTRACT Int J Exerc Sci 1(4) : [153][154][155][156][157][158][159][160][161][162] 2008. The aim of the present study was to evaluate the post-exercise blood pressure (BP) responses to two different methods of resistance exercise (RE, traditional multiple set and tri-set). Young adult men (n = 30, 19.6 ± 0.7 years old; 76.0 ± 2.7 kg; 178.2 ± 6.7 cm; 90.5 ± 5.8 MBP) with six months of previous experience in RE were selected. The volunteers were randomly assigned into three groups (n = 10, each group): non-exercised control group (CON); multiple set group (MS); and a tri-set group (TRI). The TRI group performed three consecutive exercises (3 sets of 10 repetitions with 70% of 1RM and 1 minute of rest interval after the three exercises for the same muscle group) in the following order: bench press, cross-over and peck-deck and lat pull-down, seated cable row and barbell row. The multiple set group performed 3 sets of 10 repetitions for the same exercises, but with 1 minute rest interval between each set and exercise. After the exercise sessions and control situation, individuals remained seated for BP measure every 5 minutes up to 90 minutes. The repeated measures analysis of variance (ANOVA) (2 groups by three time points) was used, followed by post-hoc Bonferroni test, for p≤0.05. There were no significant alterations for systolic and diastolic blood pressure compared with the CON group and in the moments after exercise. Heart rate was increased after exercise for both exercised groups in all post-exercise measures compared with baseline. RE method (MS or TRI) exerted no influence on post-exercise blood pressure. Post-exercise induced hypotension may require the recruitment of larger muscle groups, such as those of the lower limbs.
Resistance exercise and acute blood pressure responses
The Journal of sports medicine and physical fitness, 2015
Compare the acute hemodynamic and cardiovascular responses of high load/low repetition resistance training (RT) to low load/high repetition RT. Thirteen healthy men performed four sets of 4 repetition maximum (RM) and 20RM leg--extensions without breath--holding. The RT was conducted in a randomized order and with 48 hours between bouts. Non--invasive beat--to--beat systolic and diastolic blood--pressure (SBP/DBP) was measured on the finger, while non--invasive cardiac output (CO) was assessed beat--to--beat by impedance--cardiography. Mean ± SD resting SBP/DBP and CO were 126 ± 14/73 ± 9 mmHg and 5.6 ± 9 L min --1 , respectively. Exercise SBP/DBP values increased to 154 ± 22/99 ±18 and 203 ± 33/126 ± 19 mmHg following 4RM and 20RM RT, respectively (compared to rest, all;; p < 0.001), and 20RM SBP/DBP values were higher than 4RM values (both, p < 0.001). The SBP increased from the first to the fourth set of exercise following the 20RM load (p < 0.01), but not so for the 4RM...
Acute and chronic effects of aerobic and resistance exercise on ambulatory blood pressure
Clinics, 2010
Hypertension is a ubiquitous and serious disease. Regular exercise has been recommended as a strategy for the prevention and treatment of hypertension because of its effects in reducing clinical blood pressure; however, ambulatory blood pressure is a better predictor of target-organ damage than clinical blood pressure, and therefore studying the effects of exercise on ambulatory blood pressure is important as well. Moreover, different kinds of exercise might produce distinct effects that might differ between normotensive and hypertensive subjects. The aim of this study was to review the current literature on the acute and chronic effects of aerobic and resistance exercise on ambulatory blood pressure in normotensive and hypertensive subjects. It has been conclusively shown that a single episode of aerobic exercise reduces ambulatory blood pressure in hypertensive patients. Similarly, regular aerobic training also decreases ambulatory blood pressure in hypertensive individuals. In contrast, data on the effects of resistance exercise is both scarce and controversial. Nevertheless, studies suggest that resistance exercise might acutely decrease ambulatory blood pressure after exercise, and that this effect seems to be greater after low-intensity exercise and in patients receiving anti-hypertensive drugs. On the other hand, only two studies investigating resistance training in hypertensive patients have been conducted, and neither has demonstrated any hypotensive effect. Thus, based on current knowledge, aerobic training should be recommended to decrease ambulatory blood pressure in hypertensive individuals, while resistance exercise could be prescribed as a complementary strategy.
Effects of long-term resistance training on blood pressure: a systematic review
2018
Studies assessed the beneficial effects of aerobic exercise on blood pressure (BP); however, few studies have evaluated the effects of long-term resistance training on variations of this response. The aim of the study was to verify through a systematic review, the long-term effect of resistance training on BP. Searches were made on Medline through Pubmed, Science Direct, Scopus, Web of Science and Lilacs databases. Overall, 751 articles were found, of which 22 were further analyzed. The analysis followed the PRISMA checklist (Statement for Reporting Systematic Reviews and Meta-Analyses of Studies) and was divided according to two resistance training models: traditional resistance training (TRT), resistance training alone; or combined resistance training (CRT), resistance training associated with aerobic exercise. Greater BP reductions occurred for CRT compared to TRT. However, further studies are needed to better explicit the resistance training variables (number of exercises, repet...
Acute resistive exercise does not affect ambulatory blood pressure in young men and women
Medicine and Science in Sports and Exercise, 2001
ROLTSCH, M. H., T. MENDEZ, K. R. WILUND, and J. M. HAGBERG. Acute resistive exercise does not affect ambulatory blood pressure in young men and women. Med. Sci. Sports Exerc., Vol. 33, No. 6, 2001, pp. 881-886. Purpose: Resistive exercise elicits a pressor response that results in a dramatic increase in blood pressure (BP) during the exercise. However, it is not known if the BP elevation persists after resistive exercise. Methods: This study examined the effects of an acute resistive exercise session on 24-h ambulatory BP in sedentary (5 men, 6 women), resistance-trained (6 men, 6 women), and endurance-trained (4 men, 6 women) young subjects (age 22 Ϯ 3.2 yr) with normal BP. Two 24-h ambulatory BP recordings were made on each subject, one after two sets of resistive exercise on 12 weight machines and one after 48 h without prior exercise. Results: Systolic, diastolic, and mean arterial BP and heart rate (HR) were not different in the hours after and for up to 24 h after the single resistive exercise session compared with the control day. There also was no difference in the ambulatory BP or HR response after the single session of resistive exercise based on the training status of the subjects. Conclusion: Thus, the elevated BP that occurs during resistive exercise does not persist in the 24 h after acute resistive exercise in sedentary, resistance-trained, or endurance-trained, young, normotensive men and women.
Effect of Resistance Exercise on Hypertension
—Hypertension is a " Silent Killer " , most of the time, it has no obvious symptoms to indicate that something's wrong and many people are unaware that they have the condition. Resistance exercise has been recommended as part of the therapeutic approach in individual with hypertension. Studies have shown that resistance exercise reduces blood pressure (BP) to levels below resting values, a more stringent meta-analysis of high-quality trial evidence reported that resistance training had no effect on systolic BP and smaller overall reductions in diastolic BP (–2.2 mm Hg). A 5 mm Hg reduction in systolic BP is expected to translate into 14% and 9% reduction in stroke and coronary artery disease mortality, respectively. It is recommended that all individuals complete appropriate screening prior to commencing an exercise program (Physical Activity Readiness Questionnaire. Exercise is generally contraindicated in untreated or uncontrolled hypertensive individual with resting BP >160–180/105–110 mm Hg. Intensive isometric exercise such as heavy weight lifting can have a marked pressor effect and should be avoided. Individual with hypertension should be informed about the nature of cardiac prodromal symptoms e.g. shortness of breath, dizziness, chest discomfort or palpitation and seek prompt medical care if such symptoms develop. Follow the FITT principal when creating a resistance exercise program and should not perform concentric failure (UF). The largest isometric training reductions in resting BP have been demonstrated in hypertensive patients. We would like to propose a new A New Invention of Isometric Exercise for Individual with Hypertension-360° TitaniUM Core Strength Exercise. The clinical significance of the 360° TitaniUM Core Strength Exercise as a time-efficient and effective training modality to reduce BP, warrant further study.

Resistance training has been recommended for maintenance or improvement of the functional health of older adults, but its effect on acute cardiovascular responses remains unclear. Thus, the purpose of this study was to analyze the effect of 12 weeks of resistance training on post-exercise blood pressure (BP) in normotensive older women. Twenty-eight normotensive and physically inactive women (≥60 years) were randomly assigned to a training group (TG) or a control group (CG). The TG underwent a resistance training program (12 weeks, 8 exercises, 2 sets, 10-15 repetitions, 3 days/ week), while the CG performed stretching exercises (12 weeks, 2 sets, 20 s each, 2 days/week). At baseline and after the intervention, participants were randomly submitted to two experimental sessions: a resistance exercise session (7 exercises, 2 sets, 10-15 repetitions) and a control session. BP was obtained pre-and postsessions (90 min), through auscultation. Post-exercise hypotension was observed for systolic, diastolic, and mean BP in the TG (−6.1, −3.4, and −4.3 mmHg, respectively; P<0.05) and in the CG (−4.1, −0.7, and −1.8 mmHg, respectively; P<0.05). After the intervention period, the magnitude and pattern of this phenomenon for systolic, diastolic, and mean BP were similar between groups (TG −8.8, −4.1, and −5.7 mmHg, respectively; P<0.05 vs CG −11.1, −5.8, and −7.6 mmHg, respectively; P<0.05). These results indicate that a single session of resistance exercise promotes reduction in post-exercise BP and 12 weeks of resistance training program do not change the occurrence or magnitude of this hypotension.

The purpose of the present study was to correlate the acute and chronic decrease in blood pressure (BP) following resistance training (RT). 13 normotensive women (18-49 years) completed an acute whole body RT session with 3 sets of 10 repetitions at 60% 1RM and then 8 weeks of RT as follows: 3/week, 3 sets of 8-12 repetitions maximum. Systolic (SBP) and diastolic BP (DBP) were measured up to 60 min and 24 h following RT (acute and chronic). The greatest acute decrease of SBP (108.5±7.0 mmHg) and DBP (71.5±6.4 mmHg) values over the 60-min period were reduced compared to pre-exercise (117.3±11.7 and 79.3±8.2 mmHg, respectively; p<0.05). The chronic effect on resting BP was observed only for those presenting acute post-exercise hypotension (PEH). The change in both SBP and DBP following acute RT was correlated with the chronic change in resting SBP and DBP (r>0.5; p≤0.05). The change in 24 h BP after acute RT was correlated with the chronic reduction in SBP (r=0.74) and DBP (r=0....
Effects of isometric resistance training on blood pressure and physical fitness of men
Motriz: Revista de Educação Física
The present study aimed to investigate the effects of whole body isometric resistance training (IRT) on blood pressure (BP), strength and aerobic fitness. We also analyzed whether the effects of whole body isometric training compares to whole body dynamic resistance training (DRT). Methods: Twenty-nine pre-hypertensive sedentary males, aged between 40 and 60 years were divided into three groups: IRT (n = 10), DRT (n = 9), and Control (n = 10). Both programs involved whole body resistance training, and occurred for 12 weeks, three times/week, at an intensity of 60% of a dynamic one repetition maximum test (1RM). Before and after 12 weeks, 24 hours blood pressure monitoring, 1RM strength and aerobic fitness were assessed. Results: IRT reduced diastolic BP values during a 24-hour period and daytime. There was also a decrease in mean BP values during daytime (P < 0.05). No interaction between time and group in systolic BP, diastolic BP, mean BP, heart rate and arterial stiffness index were observed (P > 0.05). IRT increased strength and aerobic fitness when compared to Control group. However, these changes were lower than DRT regarding strength (DRT: ∆ = 43.1±10.6% vs. IRT: ∆ = 24.1±7.1% vs. CON: Δ = 4.2±11.5%; P < 0.05) and aerobic fitness (DRT: ∆ = 22.9±10.7% vs. IRT: ∆ = 12.9±6.1% vs. CON: Δ =-2.1±7.4%; P < 0.01). Conclusion: Whole body IRT reduced diastolic BP and mean BP, however, the decrease was not different for the DRT group. IRT also increased strength and aerobic fitness, nevertheless, these changes were lower than after DRT.
