A randomized controlled trial of the effects of aerobic dance training on blood lipids among individuals with hypertension on a thiazide

Efficacy of Unsupervised YouTube Dance Exercise for Patients With Hypertension: Randomized Controlled Trial

BACKGROUND

High blood pressure (BP) is linked to unhealthy lifestyles, and its treatment includes medications and exercise therapy. Many previous studies have evaluated the effects of exercise on BP improvement; however, exercise requires securing a location, time, and staff, which can be challenging in clinical settings. The antihypertensive effects of dance exercise for patients with hypertension have already been verified, and it has been found that adherence and dropout rates are better compared to other forms of exercise. If the burden of providing dance instruction is reduced, dance exercise will become a highly useful intervention for hypertension treatment.

OBJECTIVE

This study aims to investigate the effects of regular exercise therapy using dance videos on the BP of patients with hypertension, with the goal of providing a reference for prescribing exercise therapy that is highly feasible in clinical settings.

METHODS

This nonblind, double-arm, randomized controlled trial was conducted at Juntendo University, Tokyo, from April to December 2023. A total of 40 patients with hypertension were randomly assigned to either an intervention group (dance) or a control group (self-selected exercise), with each group comprising 20 participants. The intervention group performed daily dance exercises using street dance videos (10 min per video) uploaded to YouTube. The control group was instructed to choose any exercise other than dance and perform it for 10 minutes each day. The activity levels of the participants were monitored using a triaxial accelerometer. BP and body composition were measured on the day of participation and after 2 months. During the intervention period, we did not provide exercise instruction or supervise participants' activities.

RESULTS

A total of 34 patients were included in the study (16 in the intervention group and 18 in the control group). The exclusion criteria were the absence of BP data, medication changes, or withdrawal from the study. The mean age was 56 (SD 9.8) years, and 18 (53%) of the patients were female. The mean BMI was 28.0 (SD 6.3) m/kg2, and systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 139.5 (SD 17.1) mm Hg and 85.8 (SD 9.1) mm Hg, respectively. The basic characteristics did not differ between the two groups. In the multivariate analysis, SBP and DBP improved significantly in the intervention group compared to the control group (mean SBP -12.8, SD 6.1 mm Hg; P=.047; mean DBP -9.7, SD 3.3 mm Hg; P=.006).

CONCLUSIONS

This study evaluated the effects of dance exercise on patients with hypertension, as previously verified, under the additional condition of using dance videos without direct staff instruction or supervision. The results showed that dance videos were more effective in lowering BP than conventional exercise prescriptions.

The physical and psychological effects of dance therapy on middle-aged and older adult with arterial hypertension: A systematic review

Objective

To systematically review the intervention effect of dance therapy on the physical and psychological health level of middle-aged and older adult with arterial hypertension.

Methods

The databases including the Cochrane Library, PubMed, Web of Science, EBSCO, CNKI, VIP, WANFANG DATA, and Bailianyun Library, which were searched for the randomized controlled trials for identifying the effect of dance intervention on the blood pressure. The literature published from the establishment of the database to May 10, 2023, was collected for analysis. The quality of the literature was evaluated by the Cochrane bias risk assessment tool.

Results

The blood pressure in the dance intervention group were significantly improved than those of patients in the control group. However, among the mediating variables that influence the effects of dance intervention, its intensity and frequency based on the improvement of aerobic capacity were found high and low respectively, while the research on dance intervention aimed at muscle strength, endurance, and flexibility remains lacking. The movement selection and arrangement of dance therapy could integrate the physical activities with local traditional cultural characteristics.

Conclusions

It is worth noting that in the selection and arrangement of movements, dance therapy can skillfully integrate physical activities with local cultural characteristics. This unique combination not only enriches the content of dance therapy but also deepens people's understanding and recognition of traditional culture. Through this comprehensive dance intervention approach, we hope to comprehensively improve participants' physical and mental health, and promote the inheritance and development of culture.

Physical activity interventions implemented for older people in Sub-Saharan Africa: a scoping review

BACKGROUND

Sub-Saharan Africa mirrors global patterns with an expanding elderly demographic, frequently characterised by a high incidence of non-communicable diseases (NCDs), manifesting as multimorbidity. Physical activity (PA) is a validated intervention for managing the increasing prevalence of NCDs in this demographic.

OBJECTIVE

This review aimed to elucidate the extent of PA interventions implemented in Sub-Saharan Africa for managing NCDs in older people (OP).

ELIGIBILITY CRITERIA

This review synthesised randomised controlled trials published in English since 2010, focusing on PA interventions for managing NCDs or associated risk factors in OP in Sub-Saharan Africa.

SOURCES OF EVIDENCE

The Joanna Briggs Institute methodology for scoping reviews was implemented with searches in the following databases: PubMed, EBSCOhost (Academic Search Premier AfricaWide Information, CINAHL, Health Sources Premier Academic/Nursing), Scopus and ProQuest.

CHARTING METHODS

Extraction and reporting adhered to the Preferred Reporting Items for Systematic reviews and Meta-Analyses-Scoping Reviews framework, ensuring rigorous and systematic synthesis.

RESULTS

A total of 3754 studies were initially identified, with 67 studies ultimately included after applying the exclusion criteria. The synthesised trials tested primarily supervised structured PA interventions (n=30), education on PA and lifestyle (n=30) and combined structured PA with lifestyle education (n=7). A structured supervised PA regimen combining aerobic exercise at 60-80% of maximum heart rate (three 45-60 min sessions per week) and resistance training starting at 50% of one-repetition maximum (3 weekly sessions of three sets with 10-12 repetitions per muscle group), progressively increasing to 60%, was the most effective in reducing risk factors associated with NCDs in this cohort.

CONCLUSION

This analysis confirms that a structured PA regimen paired with lifestyle education significantly mitigates NCDs in Sub-Saharan Africa's elderly population. Furthermore, it highlights the imperative for further investigation into non-pharmacological strategies, especially those targeting hypertension, diabetes and cognitive health disorders.

Does dance therapy benefit the improvement of blood pressure and blood lipid in patients with hypertension? A systematic review and meta-analysis

Objective

Hypertension is a risk factor of cardiovascular disease. Dance, a type of aerobic exercise, is beneficial as a therapy in reducing blood pressure. This study aimed to systematically review the therapeutic effectiveness of dance therapy (DT) on blood pressure and blood lipid of patients with hypertension.

Methods

Searching CNKI, VIP, Wan Fang Databases, CBM, PubMed, EBSCO (MEDLINE), Cochrane Library, and Web of Science to collect randomized controlled trials (RCTs) about dance therapy in the treatment of patients with hypertension according to the inclusion and exclusion criteria, with the search time ranged from the date of database construction to January 2024. The Cochrane risk-of-bias tool and PEDro were used to evaluate the risk of included trials. The meta-analysis was implemented by using RevMan 5.4 and Stata 12.0 software.

Results

A total of 983 patients were included in 11 randomized controlled trials. According to the meta-analysis, compared with the control group, Dance Therapy effectively reduced systolic blood pressure (SBP) [MD = -7.45, 95% CI (-8.50, -6.39), p < 0.0001] and diastolic blood pressure (DBP) [MD = -2.95, 95% CI (-3.78, -2.13), p < 0.0001], and it increased high-density lipoprotein cholesterol (HDL-C) [MD = 0.20, 95% CI (-0.02, 0.42), p < 0.0001]. The subgroup analysis results showed that the treatment efficacy was more excellent with the frequency more than 3 times per week, the cycle less than 12 weeks, and the duration less than 60 min every time.

Conclusion

The results indicates that SBP, DBP, and HDL-C in hypertensive patients have been effectively improved after dance therapy intervention. In addition, it is recommended to implement dance therapy for hypertensive patients with a treatment cycle of 12 weeks, and treat at least 3 times a week, with each treatment duration controlled within 60 min.

Perturbed Lipid Metabolism Transduction Pathways in SARS-CoV-2 Infection and Their Possible Treating Nutraceuticals

The coronavirus disease 2019 (COVID-19) epidemic has evolved into an international public health concern. Its causing agent was SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), a lipid bilayer encapsulated virus. Lipids have relevance in the host's viral cycle; additionally; viruses have been speculated to manipulate lipid signaling and production to influence the lipidome of host cells. SARS-CoV-2 engages the host lipid pathways for replication, like fatty acid synthesis activation via upregulation of AKT and SREBP pathway and inhibiting lipid catabolism by AMPK and PPAR deactivation. Consequently, lipoprotein levels are altered in most cases, i.e., raised LDL, TG, VLDL levels and reduced HDL levels like a hyperlipidemic state. Apo lipoproteins, a subsiding structural part of lipoproteins, may also impact viral spike protein binding to host cell receptors. In a few studies conducted on COVID-19 patients, maintaining Apo lipoprotein levels has also shown antiviral activity against SARS-CoV-2 infection. It was speculated that several potent hypolipidemic drugs, such as statins, hydroxychloroquine, and metformin, could be used as add-on treatment in COVID-19 management. Nutraceuticals like Garlic, Fenugreek, and vinegar have the potency to lower the lipid capability acting via these pathways. A link between COVID-19 and post-COVID alteration in lipoprotein levels has not yet been fully understood. In this review, we try to look over the possible modifications in lipid metabolism due to SARS-CoV-2 viral exposure, besides the prospect of focusing on the potential of lipid metabolic processes to interrupt the viral cycle.

Characterization and critical appraisal of physiotherapy intervention research in Nigeria: a systematic review

OBJECTIVES

Clinical research is the bedrock of clinical innovation, education and practice. We characterized and critically appraised physiotherapy clinical research to avoid implementing misleading research findings into practice and to task the Nigerian physiotherapy societies on responsible conduct of clinical research.

METHODS

This is a systematic review of articles published in English between 2009 and 2023. We started with 2009 because at least few Nigerian Physiotherapy school had commenced postgraduate (research) training by then. We searched Pubmed, Medline, Cumulative Index to Nursing and Allied Health Literature, Academic Search Complete, PsycINFO and African Journal Online, and reference lists of relevant articles. We Data were selected and extracted according to predesigned eligibility criteria and using a standardized data extraction table. Where appropriate, the Pedro and Cochrane ROBINS1 were used to examine the risk of bias.

RESULTS

A total of 76 Nigerian studies were included in this study. The mean age of the study participants was 46.7 ± 8.6 years. Approximately, 45% of the participants were males. Of the clinical experiments, the randomized controlled trial (RCT) was the most common design (87.5%). Musculoskeletal conditions (39.3%) were the most studied disorder. Approximately 86% of the RCT had studies possessed fair to good quality. Interventions constituted exercise therapy (76.3%), manual therapy (8.5%) and electrotherapy (8.5%). More than half (67.8%) of the studies recorded medium to large effect sizes. A fair proportion (48.2%) of the studies had a confounding-by-indication bias. Approximately 43% of the clinical experiments were underpowered, and a few studies conducted normality tests (10.9%) and intention-to-treat analysis (37.5%).

CONCLUSIONS

RCT is the most frequent clinical experiment, with majority of them possessing fair to good quality. The most important flaws include improper computation of sample size, statistical analysis, absent intention-to-treat approach, among others. The magnitude of effects of Physiotherapy interventions varies from nil effect to large effect. Musculoskeletal condition is the most prevalent disorder and exercise is the most important intervention in Nigerian physiotherapy practice.

The effect of aerobic dancing on physical fitness and cognitive function in older adults during the COVID-19 pandemic-a natural experiment

During the Coronavirus disease (COVID-19), the physical activity of older adults is at a lower level. The study aimed to examine the effectiveness of aerobic dancing on physical fitness and cognitive function in older adults. We conducted a randomized controlled trial with 34 older adults who were assigned into an aerobic dancing group and a control group. Three dance sessions weekly for 60 ​min were scheduled for the aerobic dancing group for a total of 12 weeks. Physical fitness, blood pressure, lipids, glucose, cognitive function were assessed before and after the intervention. Baseline adjusted Analysis of Covariance (ANCOVA) was used to determine whether outcome variables varied between groups at pre-test and post-test. Effect size (Cohen's d) was calculated to determine the differences between groups from baseline to post-test. After 12 weeks, we found that the aerobic dancing group showed significant improvement in memory (portrait memory: F ​= ​10.45, p ​= ​0.003, d ​= ​1.18). The Limit of Stability (LOS) parameters in the aerobic dancing group displayed a significant increase after the intervention (right angle: F ​= ​5.90, p ​= ​0.022, d ​= ​0.60; right-anterior angle: F ​= ​4.23, p ​= ​0.049, d ​= ​0.12). Some beneficial effects were found on flexibility, grip strength, balance and subjective well-being (sit and reach: F ​= ​0.25, p ​= ​0.62, d ​= ​-0.40; grip strength: F ​= ​3.38, p ​= ​0.08, d ​= ​0.89; one-legged standing with eyes closed: F ​= ​1.26, p ​= ​0.27, d ​= ​0.50) in the aerobic dancing group. Aerobic dancing training was effective in improving memory and balance ability in older adults during the COVID-19 pandemic in China. In the future, aerobic dancing is a promising tool to encourage physical activity in older adults.

Meta-Analysis of the Effect of Aerobic Training on Blood Pressure in Hypertensive Patients

Background

We aimed to evaluate the effect of different aerobic training methods and exercise duration on blood pressure in hypertensive patients, including systolic blood pressure (SBP) and diastolic blood pressure (DBP).

Methods

Using the literature review method, the English database PubMed was retrieved to obtain relevant research literature, and the selected studies were analyzed and evaluated.

Results

14 clinical studies were included in this study, with a total of 1027 patients, including 681 in the aerobic training group and 409 in the control group. Based on heterogeneity test results, the differences of SBP and DBP before and after the physical intervention were combined using a random effect model. The results indicated that the aerobic training group could significantly reduce SBP compared with the control group, WMD = −9.91, 95% CI (-14.21, -5.61), P < 0.0001. The DBP was reduced significantly in the aerobic training group, WMD = −4.32, 95% CI (- 7.02, -1.62), P < 0.001. The results of subgroup analysis showed that both progressive training and nonprogressive training could reduce blood pressure in patients, and training time less than 12 weeks and more than 12 weeks could reduce blood pressure in patients.

Conclusion

Implementing aerobic training can effectively reduce blood pressure in hypertensive patients. Progressive training, nonprogressive training, and different training cycles can all benefit hypertensive patients.

Effects of Aerobic Training Progression on Blood Pressure in Individuals With Hypertension: A Systematic Review With Meta-Analysis and Meta-Regression

INTRODUCTION

Aerobic training of moderate intensity is the primary modality recommended in the management of hypertension. The manipulation of training variables can be an important strategy for the continuity of health benefits; however, little is known about the effects of the progression of aerobic training variables in the adaptations of blood pressure in hypertensive adults.

OBJECTIVE

To analyze, through a systematic review with meta-analysis, the effects of aerobic training with and without progression on systolic blood pressure (SBP) and diastolic blood pressure (DBP) in hypertensive adults.

METHOD

The search for the studies was carried out in the PubMed, Cochrane Central, SPORTDiscus and LILACS databases. Clinical trials that analyzed the effect of aerobic training, lasting at least six weeks, on blood pressure in hypertensive individuals comparing with a control group without intervention were selected. The selection of studies and data extraction were carried out independently by two pairs of researchers. The results are presented as mean difference and 95% confidence interval. Statistical significance was considered with p < 0.05.

RESULTS

Of the 13,028 studies found, 24 were selected and included in this review, 12 with progression of training variables and 12 without progression, with a total of 1,207 participants analyzed. There was a reduction in SBP after aerobic training with progression (-10.67 mmHg; 95% CI -15.421, -5.926; p < 0.001) and without progression (-10.17 mmHg; CI -12.213, -8.120; p < 0.001). DBP also decreased after aerobic training with progression (-5.49 mmHg; 95% CI -8.663, -2.310; p < 0.001) and without progression (-6.51 mmHg; 95% CI -9.147, -3.868; p < 0.001). According to the results of the meta-regression analyses, only age showed an association with the reduction of SBP (β: -0.323; CI -0.339, -0.307; p < 0.001).

CONCLUSION

Aerobic training promotes a reduction in the SBP and DBP levels of adults with hypertension, regardless of whether or not the training variables progression.

Characterization of dance-based protocols used in rehabilitation - A systematic review

Objective

To describe the use of dance-based intervention protocols as a rehabilitation proposal.

Method

Papers containing protocols used in adult patients and written in Spanish, English, and Portuguese were collected using the following keywords: Physical Therapy; Dance Therapy; Rehabilitation; and Clinical Trial Protocol. The PUBMED, MEDLINE, LILACS, BVS ScienceDirect, PEDro, OTseeker, The Cochrane Library (Cochrane Central Register of Controlled Trials), and Scopus databases were used for the collection of information to define the type of dance, the established protocol, pathologies, and the population involved.

Results

70 studies met the eligibility criteria, all of which presented a dance protocol. This was used in the rehabilitation of pathologies covering the neuromuscular, musculoskeletal, and cardiovascular systems, as well as in a healthy population. Positive results were the main outcome measure.

Discussion

Dance is an innovative intervention strategy for patients with comorbidities or underlying pathologies as well as for those in good health. It offers, without limitations, a field of applicability through the use of a dancing style as a rehabilitation process, generating significant changes in the physical, mental, and social skills of the individual.

A Cultural Dance Program Improves Hypertension Control and Cardiovascular Disease Risk in Native Hawaiians: A Randomized Controlled Trial

BACKGROUND

Native Hawaiians have higher hypertension (HTN) and cardiovascular disease (CVD) rates than non-Hispanic whites, calling for culturally responsive interventions to close this gap.

PURPOSE

We tested the effects of a 6-month behavioral intervention, a cultural dance program based on hula (the customary dance of Hawai'i), for improving blood pressure (BP) and CVD risk among Native Hawaiians with uncontrolled HTN.

METHODS

In a randomized controlled trial, we tested the effects of the hula-based intervention among 263 Native Hawaiians with uncontrolled HTN (systolic ≥ 140 or ≥ 130 mmHg if diabetes) and no CVD at enrollment. All participants received a brief culturally tailored heart health education before random assignment to the hula-based intervention (n = 131) or the education-only waitlist control (n = 132). Intervention received hula lessons and group-based activities for 6 months. Control received only 1-week education through 6 months.

RESULTS

Intervention yielded greater reductions in systolic (-15.3 mmHg) and diastolic (-6.4 mmHg) BP than control (-11.8 and -2.6 mmHg, respectively) from baseline to 6 months (p < .05). At 6 months, 43% of intervention participants compared to 21% of controls achieved a HTN stage <130/80 mmHg (p < .001). The 10-year CVD risk reduction was two times greater for the intervention group than the control group based on the Framingham Risk Score calculator. All improvements for intervention participants were maintained at 12 months.

CONCLUSIONS

This trial represents one of the few rigorously conducted examinations of an Indigenous practice leveraged for health promotion, with implications for other ethnic populations.

Effects of regular dance therapy intervention on blood pressure in hypertension individuals: a systematic review and meta-analysis

INTRODUCTION

Dance therapy is a non-conventional aerobic exercise in cardiovascular rehabilitation. This meta-analysis aimed to update and assess evidence from randomized controlled trials of dance therapy on patients with hypertension.

EVIDENCE ACQUISITION

PubMed, web of science, EBSCO, EMBESE, Cochrane Central Register of Controlled Trials and China National Knowledge Infrastructure databases in English or Chinese were searched and randomized controlled trials were conducted for this meta-analysis to investigate the effects of dance therapy on blood pressure in hypertension patients. Weighted mean difference (WMD) and 95% confidence intervals (CIs) were calculated. Heterogeneity was assessed by I² test.

EVIDENCE SYNTHESIS

Five studies were included according to the eligibility criteria. Dance therapy could significantly reduce the systolic/diastolic pressure of hypertension individuals (SBP:WMD -11.07mmHg; 95%CI, -14.3 to -8.12mmHg, P<0.00001;DBP:WMD-4.16mmHg;95% CI, -6.44to-1.88mmHg, P=0.0004) when compared with the control group. low heterogeneity was observed in this research (P=0.65; I²=0% to SBP; P=0.57; I² =0% to DBP). Subgroup analysis results showed that the subgroup of less than 12 weeks intervention group reduce the blood pressure more than those of 12 weeks intervention. Dance therapies reduce the SPB of hypertension individuals in African region better than Europe and America hypertension population.

CONCLUSIONS

Despite the limited number of studies and people involved, the meta-analysis further demonstrated that dance therapy could reduce SBP and DBP in patients with hypertension. The effect of dance therapy intervention on hypertension might be related to duration of intervention and population gene.

Exercise and Hyperlipidemia

Hyperlipidemia is one of the common pathological conditions of human, which occurs due to lipid metabolism disorder in the human body, resulting in serum lipid concentration beyond normal levels. Due to heredity, diet, nutrition, medicine, and other factors, the incidence of hyperlipidemia has been significantly enhanced and has become one of the most common pathological condition of the human. By introducing the background and pathogenesis of hyperlipidemia and the positive effects of exercise on a variety of related diseases, this chapter discusses the relationship between exercise and serum lipid concentration and the effects of different types of exercise on hyperlipidemia.

Effects of a 6-Week Faroese Chain Dance Programme on Postural Balance, Physical Function, and Health Profile in Elderly Subjects: A Pilot Study

The present pilot study investigates the impact of a Faroese chain dance intervention on health profile, mobility, and postural balance in elderly subjects. Healthy elderly subjects (n=27; age 75 ± 5 yrs) were randomised into an intervention group (IG) and a control group (CG). IG performed twice-weekly sessions of Faroese chain dance over 6 weeks. Dancing sessions lasted 30 min in the initial 3 weeks and 45 min in the final 3 weeks. Health profile was determined before and after intervention by measuring blood pressure, resting heart rate, muscle mass, and body fat content. Postural balance was evaluated using the Berg Balance Scale (BBS) and Fullerton Advanced Balance Scale (FAB) tests, while mobility was assessed using the Short Physical Performance Battery (SPPB), the Timed Up & Go (TUG) test, the 6-min walk test, and the 30-s sit-to-stand test. Systolic and diastolic blood pressure were lowered (9 ± 6 and 6 ± 3 mmHg, respectively) in IG, with a tendency (P=0.07) for a greater change score than in CG. Mean arterial pressure declined (P<0.05) by 7 ± 3 mmHg in IG, which tended (P=0.09) to be greater than in CG. IG improved (P<0.05) on BBS and FAB scores by 3.6 ± 2.1% and 15.8 ± 8.3%, with the change score for FAB being greater (P<0.05) than in CG (0.3 ± 1.6). Moreover, the postintervention SPPB score was improved (P<0.05) more in IG (13.9 ± 7.4%) compared to CG, while performance in the 30-s sit-to-stand, 6-min walk, and TUG tests improved (4–15%; P<0.05) in IG only. Body fat content was reduced (P<0.05) from 36.3 ± 2.8% to 34.8 ± 2.8% in IG, with no between-group differences and no change in CG (34.1 ± 2.8% to 33.7 ± 3.1%). In conclusion, a 6-week Faroese chain dance programme lowers blood pressure and improves postural balance and physical function in elderly.

The effectiveness of aerobic exercise for hypertensive population: A systematic review and meta-analysis

The study aims to evaluate the effectiveness of different durations of aerobic exercise on hypertensive patients. Four electronic databases (PubMed, Embase, Cochrane Library, and Web of Science) were searched from their inception until July 2018. English publications and randomized controlled trials involving aerobic exercise treatment for hypertensive population were included. Two reviewers independently extracted the data. The Cochrane's Risk of Bias tool was used to assess the quality of included studies. In this systematic review, a total of 14 articles were included, involving 860 participants. The quality of the included studies ranged from moderate to high. The results of the meta-analysis showed that compared with the control group, significant effects of aerobic exercise were observed on reducing systolic blood pressure (SBP) (mean difference [MD] = -12.26 mm Hg, 95% confidence interval [CI] = -15.17 to -9.34, P < 0.05), diastolic blood pressure (DBP; MD = -6.12 mm Hg, 95% CI = -7.76 to -4.48, P < 0.05), and heart rate (MD = -4.96 bpm, 95% CI = -6.46 to -3.43, P < 0.05). In addition, significant reductions were observed in ambulatory DBP (MD = -4.90 mm Hg, 95% CI = -8.55 to -1.25, P < 0.05) and ambulatory SBP (MD = -8.77mm Hg, 95% CI = -13.97 to -3.57, P < 0.05). Therefore, aerobic exercise might be an effective treatment for blood pressure improvement in hypertensive patients. However, the effectiveness between the duration of different treatment needs to be well-designed and rigorous studies will be required to verify the dataset.

Reducing effect of aerobic exercise on blood pressure of essential hypertensive patients: A meta-analysis

BACKGROUND

The comprehensive meta-analysis aimed to explore the reductive effect of aerobic exercise on blood pressure of hypertensive patients.

METHODS

The related researches were selected from PubMed and Embase databases up to June 2016. Based on specific inclusive criteria, the eligible studies were selected, and the heterogeneities in their results were estimated by χ-based Q-test and I statistics. Quantitative meta-analysis was assessed by R 3.12 software, and results were presented by standardized mean difference (SMD) and their 95% confidence intervals (CIs). Outcome indicators were systolic blood pressure (SBP) and diastolic blood pressure (DBP). The publication biases were estimated by Egger test. Besides, the "leave one out" method was used for sensitivity evaluations.

RESULTS

As a result, a total of 13 papers with 802 samples were included. Based on the meta-analysis results, there were no significant differences in SBP and DBP between aerobic and control groups before exercise (SMD = 0.15, 95%CI: -0.16-0.46; SMD = 0.16, 95% CI: -0.23-0.55). However, significant reductions were obviously in aerobic group after aerobics, compared with control (SMD = -0.79, 95% CI: -1.29 to -0.28; SMD = -0.63, 95% CI: -1.14 to -0.12). A significant publication bias was detected in SBP (t = -2.2314, P = 0.04549) but not in DBP (t = -1.4962, P = 0.1604). Additionally, the DBP result would be altered after the exclusion of 2 individual papers.

CONCLUSION

Aerobic exercise may be a potential nonpharmacological treatment for blood pressure improvement in essential hypertensive patients.
