Effect of High-Intensity Interval Training on Exercise Capacity,Blood Pressure,and Autonomic Responses in Patients With Hypertension: A Systematic Review and Meta-analysis

Abstract

Context:

Despite the well-known positive effects of exercise in hypertensive patients, the best mode of exercise is still under discussion.

Objective:

A systematic review of the literature, synthesizing data on the effects of high-intensity interval training (HIIT) on peak oxygen consumption (VO₂ peak), blood pressure (BP), cardiac autonomic modulation, and resting heart rate (HR) in patients with hypertension.

Data Sources:

MEDLINE (via PubMed), CENTRAL, PEDro database, and SciELO (from the earliest date available to December 31, 2020).

Study Selection:

Randomized controlled trials (RCTs) that evaluated the effects of HIIT in hypertensive patients.

Study Design:

Systematic review and meta-analysis.

Level of Evidence:

Level 2.

Data Extraction:

Mean differences (MDs) with a 95% CI were calculated, and heterogeneity was assessed using the I² test.

Results:

Nine RCTs encompassing 569 patients met the eligibility criteria and were included in the systematic review. Five trials compared supervised HIIT with moderate-intensity continuous training (MICT) and a control; 1 trial compared HIIT with MICT, and 3 compared HIIT with a control. In comparison with MICT, HIIT improved VO₂ peak MD (3.3 mL.kg^-1.min^-1; 95% CI, 1.4-5.3; N = 130). In comparison with controls, HIIT improved VO₂ peak MD (4.4 mL.kg^-1.min^-1; 95% CI, 2.5-6.2; N = 162).

Conclusion:

Despite the low quality of the evidence, HIIT is superior to MICT in improving VO₂ peak in patients with hypertension. HIIT effectively improved VO₂ peak, BP, and resting HR when compared with controls. HIIT appears to be safe only when performed in a supervised manner for stage 1 hypertension patients without associated risk factors.

Hypertension is the most common, costly, and preventable cardiovascular disease risk factor.³⁵ Although progress has been observed in therapeutic approaches to hypertension, the prevalence of hypertension remains high and is a leading cause of cardiovascular disease.^35,29

Because hypertension is a chronic condition needing long-term treatment, strategies with few side effects requiring less-invasive procedures should be developed.³⁸ The positive effects of various exercise protocols on the blood pressure (BP) of adults with and without hypertension have already been demonstrated.^7,11,12,37

Hence, moderate-intensity continuous training (MICT: exercise with unchanged intensity [moderate intensity]) and high-intensity interval training (HIIT: exercise that alternates between high-intensity stimuli and recovery intervals [low intensity]) stand out among the different aerobic exercise training methods used for BP control.^8,17,25,28

In addition, Leal et al,²⁸ in an elegant systematic review and meta-analysis, compared the effects of MICT and HIIT on the BP of hypertensive patients. They concluded that HIIT and MICT reduce the systolic blood pressure (SBP) in adults with hypertension, and HIIT reduced diastolic blood pressure (DBP) even further. However, they included studies on patients with other cardiovascular diseases.²⁸ Seemingly, no meta-analysis on the effects of HIIT in hypertensive subjects without other underlying cardiovascular diseases has been published.

According to Franklin,¹⁰ for patients who are sedentary and/or not used to high-intensity exercises, HIIT can sharply increase the risk of sudden cardiac death and/or acute myocardial infarction with a known or hidden cardiovascular disease. Thus, safe HIIT practice should begin under supervision, involving patients at low cardiovascular risk (stage 1 hypertension without additional risk factors), with adequate physical fitness (basic functional and structural adaptation, arising from a low- to moderate-intensity physical exercise program).^4,27 In this sense, hypertension (stage 1 with 3 or more risk factors; stage 2 with 1 or 2 risk factors; stage 3, regardless of any other risk factors) can characterize patients as at high risk of cardiovascular mortality.⁴ Therefore, this study can provide further scientific input to professionals in the field regarding the benefits and safety of supervised HIIT with this population. The present systematic review and meta-analysis aimed to analyze published randomized controlled trials (RCTs) investigating the effects of HIIT on peak oxygen consumption (VO₂ peak), BP, cardiac autonomic modulation, and resting heart rate (HR) in patients with hypertension without other underlying cardiovascular diseases.

Methods

Eligibility Criteria

This systematic review was completed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.³²

The review included RCTs that studied the effects of HIIT compared with MICT or control (no exercise) in patients with hypertension. Studies were considered eligible for this systematic review if they (1) included adult patients (aged ≥18 years) with hypertension (SBP >130 and/or DBP >80 mmHg) and without other underlying cardiovascular diseases; (2) used a randomized controlled clinical trial design; (3) compared HIIT with either MICT or a control (no exercise); (4) performed interventions for at least 4 weeks. Studies that recruited patients with other cardiac or respiratory diseases were excluded. The outcomes of interest were the peak oxygen consumption (VO₂ peak [in mL.kg^-1.min^-1]), cardiac autonomic modulation, BP, and HR.

Search Strategy for Identification of Studies

References were searched for in MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), Physiotherapy Evidence Database (PEDro), and Scientific Electronic Library Online (SciELO) up to December 2020 without language restrictions. This systematic search used a standard protocol and, whenever possible, a controlled vocabulary (MeSH terms for PubMed and Cochrane). The search strategy employed 3 groups of keywords and their synonyms: study research design, patients, and interventions. The strategy developed by Higgins et al²² was used to identify RCTs in PubMed, as shown in Appendix Table A1 (available in the online version of this article). RCTs in other databases were identified using a search strategy involving similar MeSH terms. The bibliographies of the studies included in the present systematic review were checked to identify other potentially eligible studies.

Data Collection and Analysis

Two reviewers independently checked titles and abstracts. If ≥1 reviewer considered a study eligible, the full text was obtained for a complete assessment. Then, 2 reviewers independently assessed the full text of selected studies to ascertain whether they met the eligibility criteria, and 2 authors independently extracted data from the published reports using standard data extraction forms adapted from Higgins et al.²² The following aspects were reviewed in the studies: hypertensive population, intervention (HIIT vs MICT), outcome measures, and results.

Quality of Meta-analysis Evidence

The quality of the studies was scored by 2 authors using the PEDro scale, which is based on important criteria, such as concealed allocation, intention-to-treat analysis, blinding, and adequacy of follow-up.³⁰

Summary of Findings Table

The quality of evidence for VO₂ peak, BP, and resting HR was assessed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE).¹⁸ GRADEpro GDT 2015 was used to import data from the Review Manager and to create a Summary of Findings table.¹⁹ We used the 5 GRADE items (study limitations, consistency of effect, imprecision, indirectness, and publication bias) used to assess the quality of a body of evidence provided by studies that contribute with data to a meta-analysis.²² Decisions to downgrade the quality of studies were justified in footnotes, and comments were made to help readers understand the review when necessary.^22,19

Statistical Assessment

Pooled-effect estimates were obtained by comparing the changes in least-square means from baseline to endpoint for each group and were expressed as the weighted mean difference (MD) between groups. For continuous variables, results were expressed as the MD of change in the variables between randomized groups. Conversion of nonparametric data to means and SD was based on recently established methods.⁴² When the CI but not the SD of change was available, the CI was converted into an SD, as recommended by Higgins et al,²² and calculations were made using fixed- and random-effects models. Data from multiarm RCTs were extracted regarding all relevant experimental intervention groups (HIIT vs MICT) and the control group. In follow-up reports with multiple endpoints, only data closest to the end of the exercise program were included. In crossover trials, effect sizes were extracted only at the first crossover point.

Two comparisons were made: (1) HIIT versus MICT; and (2) HIIT versus control (no exercise). Significance was set at α < 0.05. Heterogeneity among studies was examined using Cochran’s Q test and I², with values greater than 40% considered indicative of a high degree of heterogeneity²¹; then, the random-effects model was selected. Analyses were conducted using Review Manager (Version 5.3).⁶

Ethical Approval

Ethical approval was not necessary because only publicly accessible records were used, without any contact with individual participants.

Results

Description of Selected Studies

The initial search led to the identification of 1430 abstracts, from which 14 studies were considered potentially relevant and retrieved for detailed analysis. Three studies were excluded after reading the full text of the 14 papers. Of the remaining 11 studies,^{1,2,15,16,23,24,31,33,³⁴,39,41} 2 were duplicates, ie, studies involving the same participants. The study by Aguirre-Betolaza et al² used the same participants as the study by Gorostegi-Anduaga et al,¹⁵ and the study by Soltani et al³⁹ used the same participants as the study by Aghaei Bahmanbeglou et al¹. These 2 pairs were thus treated as 2 single studies. In all, 9 studies finally met the eligibility criteria.^{1,15,16,23,24,31,33,34,41} Figure 1 shows the PRISMA flow diagram of studies used in the present review. Both authors scored all studies using the PEDro scale methodology, whose results are presented individually in Appendix Table A2, available online. Following the Cochrane guidelines,⁶ a study by Gui¹⁶ was included, even though the full version of the text was unavailable. Consecutive emails requesting the full version of the text were sent, but none were answered.

Study Characteristics

The number of participants randomized in the studies included in this meta-analysis ranged from 30 to 163, with a mean age ranging from 40 to 65 years. Four studies included patients of both sexes,^15,23,24,34 while 1 included only males,¹ 2 included only females,^33,41 and 2 did not report the sex of participants.^16,31 The sample sizes, outcomes, and results of the studies are summarized in Appendix Table A3, available online. The HIIT characteristics were reported in most of the 9 studies included (Appendix Table A4, available online). Of these 9 studies, 5 compared HIIT with MICT and with the control (no exercise),^{15,24,33,34,41} 1 study compared HIIT with MICT,¹⁶ and 3 studies compared HIIT with the control.^1,23,31

Effects of HIIT Compared With Those of MICT

VO₂ peak

Three studies assessed the VO₂ peak as an outcome.^15,24,34 The total number of patients in the HIIT group was 87, while 86 patients were included in the MICT group. The HIIT studies showed a baseline average of 27.8 mL.kg^-1.min^-1 and a postintervention average of 35.2 mL.kg^-1.min^-1. The MICT studies showed a baseline average of 26.1 mL.kg^-1.min^-1 and a postintervention average of 29.7 mL.kg^-1. min^-1. There was no strong evidence of a difference in VO₂ peak between HIIT and MICT analyzing the individual findings of all studies. The meta-analysis (Figure 2A) showed a significant improvement of 2.7 mL.kg^-1.min^-1 (95% CI, 0.9-4.4; N = 173) for participants in the HIIT group compared with those in the MICT group.

The meta-analysis (Figure 2B) showed a nonsignificant difference in SBP of -1.8 mmHg (95% CI, -5.8 to 2.3; N = 172) for participants in the HIIT group compared with those in the MICT group.

Diastolic Blood Pressure

Two studies assessed DBP as an outcome.^15,34 The total number of patients in the HIIT group was 67, and 63 patients were included in the MICT group. The meta-analysis (Figure 2C) showed a nonsignificant difference in DBP of -3.8 mmHg (95% CI, -8.8 to 1.2; N = 130) for participants in the HIIT group compared with those in the MICT group.

Resting HR

Three studies assessed resting HR as an outcome.^15,33,34 The total number of patients in the HIIT group was 88, while 84 patients were included in the MICT group. The meta-analysis (Figure 2D) showed a nonsignificant difference in resting HR of -0.7 beats per minute (bpm) (95% CI, -2.5 to 1.1; N = 172) for participants in the HIIT group compared with those in the MICT group.

Effects of HIIT Versus Control

VO₂ peak

Four studies assessed VO₂ peak as an outcome.^15,23,24,34 The total number of patients in the HIIT group was 102, while 103 patients were included in the control group. The HIIT studies showed a baseline average of 27.8 mL.kg^-1.min^-1 and a postintervention average of 35.2 mL.kg^-1.min^-1. The control group studies showed a baseline average of 28.6 mL.kg^-1.min^-1 and a postintervention average of 29.6 mL.kg^-1.min^-1. The meta-analysis (Figure 3A) showed a statistically significant improvement of 4.3 mL.kg^-1.min^-1 (95% CI, 2.6-6.0; N = 205) for participants in the HIIT group compared with those in the control group.

Systolic Blood Pressure

Five studies assessed SBP as an outcome.^{15,23,31,33,34} The total number of patients in the HIIT group was 138, while 120 patients were included in the control group. The HIIT studies showed a baseline average of 138.3 mmHg and a postintervention average of 131.8 mmHg. The control group studies showed a baseline average of 139.5 mmHg and a postintervention average of 137.3 mmHg. The meta-analysis (Figure 3B) showed a significant reduction in SBP of -4.7 mmHg (95% CI, -7.7 to -1.8; N = 258) for participants in the HIIT group compared with those in the control group.

Diastolic Blood Pressure

Four studies assessed DBP as an outcome.^15,23,31,34 The total number of patients in the HIIT group was 117, while 100 patients were included in the control group. The meta-analysis (Figure 3C) showed a significant reduction in DBP of -4.4 mmHg (95% CI, -8.2 to -0.5; N = 217) for participants in the HIIT group compared with those in the control group.

Resting HR

Three studies assessed resting HR as an outcome.^15,23,33 The total number of patients in the HIIT group was 78, whereas 75 patients were included in the control group. The meta-analysis (Figure 3D) showed a significant reduction in resting HR of -2.2 bpm (95% CI, -2.3 to -1.0; N = 153) for participants in the HIIT group compared with those in the control group.

Cardiac Autonomic Modulation

Aguirre-Betolaza et al² examined the effects of 16 weeks of practicing different aerobic training programs on cardiac autonomic modulation and hemodynamics in patients with hypertension. Participants were randomly assigned to an attention control (AC) group (physical activity recommendations) or 1 of 3 supervised exercise training groups: high-volume MICT, high-volume HIIT, and low-volume HIIT. After the intervention, the HR, SBP, and DBP at rest and during submaximal exercise, and the diurnal and nocturnal SBP and DBP values decreased (P < 0.05) in all groups with no differences between them. When the exercise training groups were combined, submaximal SBP (P = 0.05) and DBP (P = 0.004), VO₂ peak (P = 0.01), and HR reserve (P = 0.03) were significantly improved compared with AC. Moreover, they concluded that the greatest improvements in autonomic function were found when the aerobic training was individually designed and supervised, irrespective of intensity and volume of exercise.²

GRADE Assessments

The GRADE assessments are presented in the Summary of Findings Table A5 and A6 (Appendix, available online). Compared with MICT (Table A5), the quality of evidence for the VO₂ peak was assessed as high; for SBP, low; and for DPB and resting HR, moderate. Compared with the control (Table A6), the quality of evidence for the VO₂ peak was assessed as high; for SBP and DBP, low; and for resting HR, moderate.

Discussion

The main findings of the present study indicate that supervised HIIT improved VO₂ peak more effectively than MICT in patients with hypertension (stage 1 and stage 2). However, we cannot claim that HIIT is completely safe for hypertensive patients with an elevated risk of cardiovascular mortality (hypertension; stage 1 with ≥3 risk factors; stage 2 with 1 or 2 risk factors; stage 3 regardless of other risk factors).

In summary, supervised HIIT effectively increases VO₂ peak in stage 1 and stage 2 hypertensive patients during a short-term exercise program. The quality of evidence for the VO₂ peak was assessed as high. The degree of improvement in VO₂ peak with HIIT was approximately 2 times greater than with MICT and 5 times greater than in control groups. Thus, the strength of this study is that we included a VO₂peak, which is an important outcome associated with prognosis in patients with hypertension.^9,26 Faselis et al⁹ found an inverse relationship between exercise capacity and progression from prehypertension to hypertension. There was also a significant negative correlation between BP and VO₂ peak.⁵

It is well established by previous meta-analyses that regular aerobic exercise is an effective strategy to reduce clinical BP measurements in normotensive, prehypertensive, and hypertensive adults.²⁸ However, in this study, although HIIT improved SBP when compared with control, the quality of evidence was low for SBP and DBP and moderate for resting HR. From a public health perspective, there is strong evidence to support that reduced SBP is linearly associated with a lower risk of cardiovascular morbidity and mortality in adults with hypertension.^{7,20,24,29,38} For instance, a reduction of 10 mmHg in SBP or 4 mmHg in DBP is associated with approximately 30% lower risk of stroke and approximately 20% lower risk of myocardial infarction.⁴⁰

The results of this meta-analysis concur with those of previous systematic reviews that compared the effects of HIIT and MICT on the VO₂ peak in patients with heart disease.^13,14 HIIT may improve peak oxygen uptake and should be considered as a component of care in the treatment of patients with cardiovascular disease with caution for those with underlying heart disease.³⁶ Recently, Hannan et al²⁰ published a systematic review and meta-analysis that investigated cardiorespiratory fitness changes resulting from HIIT or MICT in a population of patients with heart disease. They concluded that supervised HIIT performed better than MICT in improving cardiorespiratory fitness and that it is as safe as MICT for cardiac rehabilitation participants.^18,20

Despite the favorable results, strategies to increase participation and adherence to HIIT in hypertensive patients are essential to maintain and improve their exercise capacity and BP.³ It is also important to acknowledge the barriers to the implementation of a physical exercise program in this population.³⁶

Study Limitations

The results of this systematic review are limited by the lack of multicenter, high-quality, long-term studies. This highlights the paucity of high-quality research comparing HIIT and MICT in patients with hypertension. Given the significant heterogeneity found in the primary analyses—owing to the variety of HIIT protocols used (variable intensities and different exercise program durations)—and the very low-quality evidence, interpretation should be undertaken with considerable caution. Nonetheless, the biases involved in this systematic review are minimized by the methodological quality criteria, the 2 independent reviewers, the in-depth search in multiple databases with no restrictions of language or date of publication, and the specific analytical tools.

Conclusion

Supervised HIIT is superior to MICT in improving VO₂ peak in patients with hypertension (stage 1 and stage 2). HIIT also effectively improved VO₂ peak, BP, and resting HR in this population in comparison with controls. There is not enough evidence that supervised HIIT is more effective than MICT to improve cardiac autonomic modulation in patients with hypertension. Although certain benefits have been demonstrated, only the possible benefits of HIIT to VO₂ peak can be stated because of the low-quality evidence. No serious adverse events were reported in the included studies; nevertheless, HIIT is not completely safe for hypertensive patients at considerable risk of cardiovascular mortality. This training proposal is safe only when supervised in fit patients at low cardiovascular risk (patients with stage 1 hypertension without associated risk factors).

Clinical Messages

There is a lack of scientific evidence on the effects of supervised HIIT versus MICT on cardiac autonomic modulation, VO₂ peak, BP, and resting HR in patients with hypertension.

There is not enough evidence that supervised HIIT is more effective than MICT to improve cardiac autonomic modulation in hypertensives.

Supervised HIIT was more effective than MICT in improving VO₂ peak, with significant statistical and clinical improvements in stage 1 and stage 2 hypertensive patients.

HIIT cannot yet be considered completely safe for patients at considerable risk of cardiovascular mortality (hypertension; stage 1 with ≥3 risk factors; stage 2 with 1 or 2 risk factors; stage 3, regardless of other risk factors) without other underlying cardiovascular diseases.
