exercise in hypertensive individuals: systematic review and meta-analysis. Rev Bras Fisiol Exerc. 2025;24(1);e245622. doi: 10.33233/rbfex.v24i1.5622
Abstract
Introduction: Systemic arterial
hypertension (SAH) is one of the most common cardiovascular diseases.
Sedentarism and physical inactivity may contribute to worsening this condition,
increasing treatment costs and decreasing rehabilitation chances and life
expectancy. Combined exercise practice may be an alternative to address this
health issue, offering excellent cost-effectiveness. Objective: To review the effect of combined exercise (aerobic
exercise associated with resistance exercise) on rehabilitating patients with
SAH. Methods: This is a
systematic review using the PICO strategy, with searches conducted in the PubMED, OVID, Web of Science, PEDro,
LILACS, and SciELO databases, using the following
descriptors: arterial hypertension, elevated blood pressure, heart disease,
hypertensive individuals, resistance exercise, aerobic exercise, combined
exercise, resistance activities, and strength training, combined with the
Boolean operators "AND" and "OR". Results: Five studies were included after
selection. The combined exercise was effective in reducing blood pressure in
patients, with a mean reduction of systolic blood pressure -0.73 mmHg; 95% CI,
-1.12 to –0.34 and diastolic blood pressure -0.67 mmHg; 95% CI, -1.06 to –0.29.
Conclusion: Combined training proved to be
effective in treating patients with SAH.

Systemic arterial hypertension (SAH) is a common chronic condition that affects millions of people worldwide, being responsible for various functional limitations, such as reduced physical capacity and increased cardiovascular risk [1]. Hypertensive individuals often experience difficulty performing daily activities due to impairment of the cardiovascular system and muscle function [2]. Regular physical exercise, especially resistance exercise and aerobic exercise, has been identified as an effective intervention to improve cardiovascular function and quality of life in these patients [3,4].
Functional limitations in hypertensive individuals develop primarily due to increased arterial stiffness, endothelial dysfunction, and loss of muscle mass, processes that compromise the efficiency of the cardiovascular and muscular systems [5]. Additionally, hypertension can trigger a vicious cycle of sedentary behavior, further exacerbating these limitations and increasing the risk of comorbidities such as stroke and heart failure [6,7]. The progression of these limitations is often silent, making early diagnosis and effective management of the condition more challenging.
Aerobic exercise improves cardiovascular capacity and the efficiency of the circulatory system in hypertensive individuals, helping to reduce blood pressure levels and increase physical endurance [8]. On the other hand, resistance exercise contributes to increased muscle strength, improved body composition, and enhanced muscle functionality, which are essential for functional independence [9]. The combination of these two types of exercises has shown promising results in improving both cardiovascular health and the overall functional capacity of hypertensive individuals [10].
This study is justified by the need
to gain a deeper understanding of the combined effects of resistance and
aerobic exercise on the functionality and cardiovascular health of hypertensive
individuals. Although there is evidence highlighting the benefits of each type
of exercise separately, few studies have investigated the efficacy of a
combined protocol. The aim of this study is to review the impacts of combining
resistance and aerobic exercises on the blood pressure of individuals with systemic
arterial hypertension.
Study type and registration
This systematic review was conducted
following the guidelines of the Preferred Reporting Items for Systematic
Reviews and Meta-Analyses (PRISMA)
[11]. This study was registered in the International Prospective Register of
Systematic Reviews (PROSPERO)
under the number CRD42025633308.
For this systematic review, the PICOS strategy was used, where the population studied consisted of patients with systemis arterial hypertension. The intervention involved performing both aerobic and resistance training, in comparison with patients who did not engage in any of these activities or performed only one of them. The outcomes were related to blood pressure, lean body mass, strength, and cardiorespiratory function.
Randomized clinical trials were used, with no restrictions on language or year. To be eligible, the clinical trial had to study aerobic exercise combined with resistance training in individuals of both sexes, aged over 18 years, and diagnosed with systemic arterial hypertension. The studies were excluded if the patients had comorbidities other than systemic hypertension, if diuretics or beta-blockers were used with the exercise, if only aerobic or resistance exercise was assessed individually, or if blood pressure was assessed at a time other than pre- and post-training, for example during sleep.
Sources of information
We conducted a computer-based search,
consulting PubMED, OVID, Web of Sciences,
Physiotherapy Evidence Database (PEDro), Latin American and Caribbean Health
Sciences Literature (LILACS), and Scientific Electronic Library Online
(SciELO). We also searched the reference lists of previous systematic reviews
and eligible clinical trials for this review. The search for articles was
completed in December 2024.
Search
The research was based on the
previously described PICOS strategy and the Boolean operators AND and OR. The search strategy is presented in Supplement 1.
Data collection process
For the extraction of selected articles, titles were reviewed (first stage), followed by abstracts (second stage), and full-text reading (third stage). Subsequently, an exploratory reading of the selected studies was conducted, followed by a selective and analytical reading. The data extracted from the articles were summarized by author, journal, year, title, and conclusions to gather key information for the research.
The assessment of the methodological quality of the studies was conducted by two independent reviewers. In cases of disagreement between them, the article was read in fully for reevaluation. If the disagreement persisted, a third reviewer assessed the study and made the final decision.
Data items
Four authors independently extracted
data from the published reports using a standardized data extraction process,
considering study population aspects such as mean age, sex, number of patients,
and diagnosis, as well as aspects of the intervention performed, including
sample size, type of inspiratory muscle training, presence of supervision,
intensity, frequency, and duration of each session. Additionally, follow-up,
loss to follow-up, outcome measures, and reported results were analyzed.
Quality of each study
The methodological quality was assessed
using the PEDro scale, which scores 11 items: (1) eligibility criteria, (2)
random allocation, (3) concealed allocation, (4) baseline comparison, (5)
blinding of participants, (6) blinding of therapists, (7) blinding of
assessors, (8) adequate follow-up, (9) intention-to-treat analysis, (10)
between-group comparisons, and (11) point estimates and variability. Items are
scored as present (1) or absent (0), resulting in a maximum total score of 10
points, as the first item is not included in the final score.
Synthesis of results
The presence of heterogeneity was evaluated using the Chi2 test and the I2 statistic. This statistic illustrates the percentage of variability in effect estimates from heterogeneity rather than sampling error.
Statistical assessment
The mean difference between groups and the respective 95% confidence intervals were calculated and used to quantify the effect of continuous outcomes. For the meta-analyzes in which the studies used the same scales, the results were presented as mean difference (MD) and 95% confidence intervals. Otherwise, the effects were calculated using standardized mean difference (SMD) and 95% confidence intervals. The effect size of the interventions was defined as small (MD < 10% of the scale or SMD < 0.4); moderate (MD = 10% to 20% of the scale or SMD = 0.41 to 0.7) or large (MD > 20% of the scale or SMD > 0.7).
Selection and characteristics
of the studies
According to the data presented in the
article selection flowchart (Figure 01), the database search yielded a total of
866 articles. Initially, 543 were excluded based on title screening. Then, out
of the 189 articles evaluated based on abstract reading, 165 were considered
not directly related to the topic of this study. Thus, 24 articles were
selected for full-text reading. Of these, 10 were excluded for using only
aerobic activity as a treatment for hypertension, and 9 for not evaluating both
aerobic and resistance activities together. Therefore, this systematic review
included 5 articles that met the eligibility criteria for inclusion in the
present review.

Sistolic blood pressure
Four studies analyzed the impact of exercise on systolic blood pressure. For the meta-analysis of this comparison, a random model was used (I2 = 92%, df = 3, p < 0.00001), in which there was a statistically significant difference between the groups in the comparison between the exercise and the control (difference between the means -0.73 mmHg; 95% CI, -1.12 to –0.34; Fig. 2).

Diastolic blood pressure
Four studies analyzed the impact of exercise on diastolic blood pressure. For the meta-analysis of this comparison, a random model was used (I2 = 91%, df = 3, p < 0.00001), in which there was a statistically significant difference between the groups in the comparison between the exercise and the control (difference between the means -0.67 mmHg; 95% CI, -1.06 to –0.29; Fig. 3).
Figure 3 - Forest plot of the results of the meta-analysis
The literature on the effects of physical exercise in reducing blood pressure in hypertensive individuals is extensive and consistently highlights the efficacy of both aerobic exercise and resistance exercise, whether performed separately or in combination. Although the magnitude of the response may vary depending on the type of exercise, the duration of the program, and the characteristics of the studied population, the findings suggest that physical exercise, in general, provides substantial benefits in hypertension management.
The reduction in blood pressure observed in the reviewed studies aligns with what is widely reported in the literature, where both aerobic and resistance exercise have positive effects on BP. Caminiti et al. [14], for example, observed significant BP reductions after 12 weeks of training, with no differences between groups that performed aerobic exercise followed by resistance training. This lack of difference between modalities can be explained by the mechanics of exercise, where both aerobic and resistance training contribute to BP reduction through distinct but complementary mechanisms. Aerobic exercise, by improving crdiorespiratory fitness, helps decrease peripheral vascular resistance and enhances endothelial function. Meanwhile, resistance training, by increasing muscle mass may reduce arterial stiffness and promote better regulation of the autonomic nervous system. These combined effects may be responsible for the overall BP reduction observed, regardless of the exercise order.
On the other hand, the study by Pedralli et al. [15], which investigated different training modalities (aerobic, resistance, and combined), indicated that aerobic exercise had a stronger impact on systolic blood pressure, with a reduction of 5.1 mmHg, while the resistance group experienced a decrease of 4.0 mmHg. This finding is consistent with previous studies suggesting that aerobic exercise has a more pronounced effect on SBP due to increased blood volume and improved cardiac and vascular function, facilitating a reduction in pressure during physical exertion. The underlying mechanism involves cardiovascular adaptations that decrease arterial stiffness and enhance endothelial function, both critical factors in blood pressure regulation. Additionally, Alemayehu et al. [17] observed a more significant reduction in their participants after 12 weeks of combined exercise, with a drop of 17.75 mmHg in SBP and 12.5 mmHg in diastolic blood pressure. This could be explained by the broader range of physiological adaptations promoted by combined training, which impacts both the cardiovascular system and increases in muscle mass and strength—two factors that may interact to enhance BP control more effectively.
Another important aspect observed in the studies was the favorable response of exercise in managing more resistant cases of hypertension, as seen in the study by Pires et al. [16], which focused on patients with resistant hypertension. After eight weeks of aerobic, resistance, and combined exercise, participants showed a significant reduction in ambulatory blood pressure, a particularly relevant finding since patients with resistant hypertension often struggle to control BP despite using multiple medications. In these cases, exercise may help not only by reducing peripheral vascular resistance but also by improving function and modulating the sympathetic nervous system, both of which are often dysregulated in resistant hypertensive patients. These findings are supported by Masroor et al. [17], who observed a significant BP reduction in sedentary women with hypertension after just four weeks of combined training, reinforcing the idea that even short-term exercise programs can provide substantial benefits.
The reduction in blood pressure (BP) observed after exercise can be explained by several physiological mechanisms. Aerobic exercise improves the efficiency of the cardiovascular system by increasing the heart's ability to pump blood and promoting the dilation of blood vessels, mainly through the improvement of endothelial function, which increases the release of nitric oxide, promoting vasodilation [19]. Additionally, aerobic exercise increases plasma volume, reducing blood viscosity and facilitating blood flow, which contributes to a decrease in peripheral vascular resistance [20]. On the other hand, resistance exercise increases muscle mass, creating a larger "reservoir" of blood in the muscles, which reduces peripheral resistance and, consequently, BP [21]. It also improves endothelial function and decreases sympathetic nervous system activation, reducing vasoconstriction and contributing to BP control [22]. The combination of both types of exercise results in a more robust response, affecting both the cardiovascular and musculoskeletal systems, with adaptations that help effectively control BP [23].
Studies focusing on populations with resistant hypertension, such as Pires et al. [16], indicate that exercise can be a particularly valuable intervention, especially when combined with pharmacological therapy. Resistant hypertension is often associated with vascular control imbalances, impaired renal function, and heightened sympathetic nervous system activity, and exercise may help mitigate these effects. The activation of the parasympathetic nervous system and the reduction in sympathetic activity during exercise appear to be key factors contributing to the observed improvements in blood pressure.
The main limitations of this study include high heterogeneity among the studies selected for the meta-analysis, which may have influenced the consistency of the results and the interpretation of the data. Variability in methods, populations, and interventions across the included studies makes it difficult to generalize the conclusions and may reduce the precision of the estimates. Additionally, the number of volunteers in the studies does not necessarily guarantee robustness in the findings, as there is the possibility of statistical errors leading to spurious results. These errors may occur due to uncontrolled variabilities or flaws in study design, affecting the validity of the conclusions. These limitations suggest that the results should be interpreted with caution, and further research with standardized methodologies is needed to confirm the findings.
In summary, the reviewed studies reinforce the importance of physiscal exercise in hypertension management, emphasizing aerobic and resistance modalities, particularly combined training, which appears to offer the greatest benefits. The physiological response to exercise involves cardiovascular and musculoekeletal adaptations that work synergistically to lower blood pressure. Although aerobic exercise seems to have a more pronounced effect on reducing systolic blood pressure, combined training provides additional benefits, especially for individuals with more severe or resistant hypertension. Thus, the prescription of physical exercise should be considered an effective therapeutic strategy in hypertension treatment, serving as an alternative or complement to traditional pharmacological treatments.
