Abstract
We aimed to assess the effect of exercise training on heart rate variability (HRV) in hypertensive patients and to provide practical recommendations. We systematically searched seven databases for randomized controlled trials (RCTs) comparing the efficacy of exercise interventions vs. non-exercise control for HRV in adults with hypertension. HRV parameters, blood pressure (BP), and heart rate (HR) from the experimental and control groups were extracted to carry out meta-analysis. To explore the heterogeneity, we performed sensitivity analysis, sub-analysis, and meta-regression. Twelve RCTs were included, and the main results demonstrated exercise produced improvement in root mean square of successive RR-intervals differences (RMSSD) and high frequency (HF), and reductions in LF/HF, resting systolic blood pressure (SBP), and HR. The sub-analysis and meta-regression showed that AE improved more HRV indices and was effective in reducing BP compared with RE. Follow-up duration was also an important factor. Data suggests exercise training has ameliorating effects on HRV parameters, resting SBP, and HR in hypertensive patients, showing enhanced autonomic nervous system function and vagal activity. This effect may be better realized with exercise interventions of 4 weeks or more. Considering our results and the hypertension practice guidelines, we tend to recommend patients choose supervised AE.

Abstract
Background Hypertension is a global issue that is projected to worsen with increasingly obese populations. The central nervous system including the parts of the cortex plays a key role in hemodynamic stability and homeostatic control of blood pressure (BP), making them critical components in understanding and investigating the neural control of BP. This study investigated the effects of anodal transcranial direct current stimulation (tDCS) associated with aerobic physical exercise on BP and heart rate variability in hypertensive patients. Methods Twenty hypertensive patients were randomized into two groups: active tDCS associated with aerobic exercise or sham tDCS associated with aerobic exercise. BP and heart rate variability were analyzed before (baseline) and after twelve non-consecutive sessions. After each tDCS session (2 mA for 20 min), moderate-intensity aerobic exercise was carried out on a treadmill for 40 min. Results A total of 20 patients were enrolled (53.9 ± 10.6 years, 30.1 ± 3.7 Kg/m2). There were no significant interactions between time and groups on diastolic BP during wake, sleep, over 24 and 3 h after the last intervention. Heart rate variability variables showed no significant difference for time, groups and interaction analysis, except for HF (ms2) between groups (p < 0.05). Conclusion Anodal tDCS over the temporal cortex associated with aerobic exercise did not induce improvements in BP and heart rate variability.

Abstract
Hypertension is the leading risk factor for cardiovascular disease yet also one of the most readily preventable causes of death. Isometric resistance training (IRT) has gained increasing popularity in recent times as a viable nonpharmacological management option for hypertension. Whilst there have been several reviews on this topic, with varying findings, this umbrella review aimed to summarize the current evidence underpinning the effectiveness of IRT for hypertension. Quantitative systematic reviews and meta-analyses published in English were considered for inclusion. Commercially produced and grey literature was searched between December 2021 and January 2022. Methodological quality of included reviews was determined using the AMSTAR 2 critical appraisal tool. Customized data extraction tools were developed for this review and data were synthesized using the National Health and Medical Research Council FORM Framework. Twelve reviews published between 2011 and 2021 of varying methodological quality were identified. Isometric handgrip exercise training with four sets of 2-min contractions and 1 min rest period between each set was the most utilized intervention, undertaken three times per week for at least 8 weeks. Collectively, there is consistent evidence to indicate IRT has positive impacts on SBP and DBP as well as mean arterial pressure. These positive impacts were reported for normotensive as well as hypertensive individuals. Given IRT is a readily available, easy-to-use intervention with minimal financial cost, it could be considered a viable treatment option for people with, and at risk of, hypertension.

The Western and Chinese exercise training for blood pressure reduction among hypertensive patients: An overview of systematic reviews. J Clin Hypertens (Greenwich) 2023.

Abstract
Hypertension remains the world's leading cause of premature death. Interventions such as exercise, diet modification, and pharmacological therapy remain the mainstay of hypertension treatment. Numerous systematic reviews and meta-analyses demonstrated the effectiveness of western exercises, such as aerobic exercise and resistance exercise, in reducing blood pressure in hypertensive patients. There is recently emerging evidence of blood pressure reduction with Chinese exercises, such as Tai Chi, Baduanjin, and Qigong. The current overview of systematic reviews aims to evaluate the quality and descriptively summarize the evidence for the effectiveness of western and Chinese exercises for hypertension management. Thirty-nine systematic reviews were included in this overview, with 15 of those being on Chinese exercise. Evidence suggests that exercise training, regardless of Western or Chinese exercise, generally reduced both systolic and diastolic blood pressure. High-intensity intermittent training did not further reduce blood pressure when compared to moderate-intensity continuous training. Conflicting results on the effectiveness of blood pressure reduction when comparing Chinese and Western exercise training were observed. This suggests the comparable effectiveness of Chinese exercise training, in particularly Tai Chi, to general or aerobic exercise training in terms of blood pressure reduction. The Chinese exercise modality and intensity may be more suitable for the middle-aged and elderly population.

Effects of dynamic, isometric and combined resistance training on blood pressure and its mechanisms in hypertensive men. Hypertens Res 2023; 46:1031-1043. [PMID: 36759659 PMCID: PMC9909153 DOI: 10.1038/s41440-023-01202-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 12/26/2022] [Accepted: 01/20/2023] [Indexed: 02/11/2023]
Abstract
Although dynamic resistance training (DRT) and isometric handgrip training (IHT) may decrease blood pressure (BP) in hypertensives, the effects of these types of training have not been directly compared, and a possible additive effect of combining IHT to DRT (combined resistance training-CRT), has not been investigated. Thus, this study compared the effects of DRT, IHT and CRT on BP, systemic hemodynamics, vascular function, and cardiovascular autonomic modulation. Sixty-two middle-aged men with treated hypertension were randomly allocated among four groups: DRT (8 exercises, 50% of 1RM, 3 sets until moderate fatigue), IHT (30% of MVC, 4 sets of 2 min), CRT (DRT + IHT) and control (CON - stretching). In all groups, the interventions were administered 3 times/week for 10 weeks. Pre- and post-interventions, BP, systemic hemodynamics, vascular function and cardiovascular autonomic modulation were assessed. ANOVAs and ANCOVAs adjusted for pre-intervention values were employed for analysis. Systolic BP decreased similarly with DRT and CRT (125 ± 11 vs. 119 ± 12 and 128 ± 12 vs. 119 ± 12 mmHg, respectively; P < 0.05), while peak blood flow during reactive hyperaemia (a marker of microvascular function) increased similarly in these groups (774 ± 377 vs. 1067 ± 461 and 654 ± 321 vs. 954 ± 464 mL/min, respectively, P < 0.05). DRT and CRT did not change systemic hemodynamics, flow-mediated dilation, and cardiovascular autonomic modulation. In addition, none of the variables were changed by IHT. In conclusion, DRT, but not IHT, improved BP and microvascular function in treated hypertensive men. CRT did not have any additional effect in comparison with DRT alone.

Abstract
High blood pressure causes 45% of deaths from heart diseases and 51% of deaths from stroke. OBJECTIVE To conduct systematic search and summarize the systematic reviews and/or meta-analyses about impact of isometric training on blood pressure. MATERIAL AND METHODS Systematic search for publications in PubMed, Cochrane Library and Epistemonikos databases for the period from January of 2017 yr. to 19 of January 2023 yr. was carried out. The search was done by keywords: isometric exercises, isometric training, blood pressure, arterial hypertension, static resistance training, handgrip test. Methodological quality of included articles was assessed using the «Assessment of methodological quality of systematic reviews» (AMSTAR-2) tool. The number of systematic reviews equal 15 was analyzed. RESULTS The overall methodological quality of 15 included reviews, obtained by AMSTAR-2, revealed a very low confidence rate (critically low confidence, 10 publications) for results of systematic review and meta-analyses. In total, analysis and generalization of all results of included systematic reviews about blood pressure decrease by isometric training showed, that systolic blood pressure against the background of this method decreases on average by 6.1±2.0 mm Hg, and diastolic blood pressure - by 3.0±1.0 mm Hg. CONCLUSION Authors of 15 systemic reviews, included in an umbrella study, reached a common conclusion about isometric training efficacy in secondary prevention of arterial hypertension.

The effectiveness and safety of isometric resistance training for adults with high blood pressure: a systematic review and meta-analysis. Hypertens Res 2021; 44:1373-1384. [PMID: 34385688 DOI: 10.1038/s41440-021-00720-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 07/03/2021] [Accepted: 07/11/2021] [Indexed: 02/07/2023]
Abstract
High blood pressure (BP) is a global health challenge. Isometric resistance training (IRT) has demonstrated antihypertensive effects, but safety data are not available, thereby limiting its recommendation for clinical use. We conducted a systematic review of randomized controlled trials comparing IRT to controls in adults with elevated BP (systolic ≥130 mmHg/diastolic ≥85 mmHg). This review provides an update to office BP estimations and is the first to investigate 24-h ambulatory BP, central BP, and safety. Data were analyzed using a random-effects meta-analysis. We assessed the risk of bias with the Cochrane risk of bias tool and the quality of evidence with GRADE. Twenty-four trials were included (n = 1143; age = 56 ± 9 years, 56% female). IRT resulted in clinically meaningful reductions in office systolic (-6.97 mmHg, 95% CI -8.77 to -5.18, p < 0.0001) and office diastolic BP (-3.86 mmHg, 95% CI -5.31 to -2.41, p < 0.0001). Novel findings included reductions in central systolic (-7.48 mmHg, 95% CI -14.89 to -0.07, p = 0.035), central diastolic (-3.75 mmHg, 95% CI -6.38 to -1.12, p = 0.005), and 24-h diastolic (-2.39 mmHg, 95% CI -4.28 to -0.40, p = 0.02) but not 24-h systolic BP (-2.77 mmHg, 95% CI -6.80 to 1.25, p = 0.18). These results are very low/low certainty with high heterogeneity. There was no significant increase in the risk of IRT, risk ratio (1.12, 95% CI 0.47 to 2.68, p = 0.8), or the risk difference (1.02, 95% CI 1.00 to 1.03, p = 0.13). This means that there is one adverse event per 38,444 bouts of IRT. IRT appears safe and may cause clinically relevant reductions in BP (office, central BP, and 24-h diastolic). High-quality trials are required to improve confidence in these findings. PROSPERO (CRD42020201888); OSF ( https://doi.org/10.17605/OSF.IO/H58BZ ).
