Effect of m-Health-Based Interventions on Blood Pressure: An Updated Systematic Review with Meta-Analysis.

Background: In recent years, the integration of mobile health (m-Health) interventions has garnered increasing attention as a potential means to improve blood pressure (BP) management in adults. This updated systematic review with meta-analysis aimed to identify the effect of m-Health-based interventions on BP in adults and to evaluate the effect of m-Health on BP according to the characteristics of subjects, interventions, and countries. Methods: The search was carried out in PubMed, Embase, ResearchGate, and Cochrane databases in January 2022. Study selection and data extraction were performed by two independent reviewers. For analysis, random effects models were used with a confidence interval (CI) of 95% and p < 0.05. Results: Fifty studies were included in this review and in the meta-analysis. Interventions with m-Health reduced systolic BP in 3.5 mmHg (95% CI -4.3; -2.7; p < 0.001; I2 = 85.8%) and diastolic BP in 1.8 mmHg (95% CI -2.3; -1.4; p < 0.001; I2 = 78.9%) compared to usual care. The effects of m-Health interventions on BP were more evident in men and in older adults, in interventions lasting 6-8 weeks, with medication reminders, with the possibility of insertion of BP values (p < 0.05). Conclusion: The results of this study support the effectiveness of m-Health in reducing BP when compared to standard care. However, these effects are dependent on the characteristics of the subjects and interventions. Given the substantial heterogeneity among the results of this systematic review with meta-analysis, its interpretation should be cautious. Future research on this topic is warranted.

Blood Pressure and Blood Glucose Responses to Combined Exercise Sessions of Different Intensities in Individuals with Cardiovascular Risk Factors.

OBJECTIVE: The purpose of the present study was to verify the acute effects of blood pressure and blood glucose after two sessions of combined exercise sessions performed at two levels of intensity in trained individuals with cardiovascular risk factors. METHODS: Eighteen individuals (66.22 ± 8.61 years) of both sexes (6 women/12 men) with cardiovascular risk factors performed two sessions of combined exercises at different levels of intensity: moderate (MOD) and high (HI). To control the intensity of the aerobic training, the Borg Rating of Perceived Exertion (RPE) Scale was used. For the strength training, the maximum number of repetitions was carried out within a predetermined duration of sets. Blood pressure and blood glucose measurements were collected before and 20 minutes after the sessions. The data were analyzed using Generalized Estimating Equations, α 5%. RESULTS: Reductions were observed in systolic blood pressure (MOD - Δ = -4.95 mmHg; HI - Δ = -3.31 mmHg) and blood glucose (MOD - Δ = -16.06 mg/dL; HI - Δ = -29.45 mg/dL) after the two sessions, with no difference between sessions. Diastolic blood pressure did not change (p < .05). CONCLUSION: Combined exercises sessions of moderate or high intensity can promote an acute reduction in systolic blood pressure and glycemia in individuals with cardiovascular risk factors.

Effects of Nonperiodized and Linear Periodized Combined Training on Health-Related Physical Fitness in Adults With Obesity: A Randomized Controlled Trial.

ABSTRACT: Streb, AR, Passos da Silva, R, Leonel, LdS, Possamai, LT, Gerage, AM, Turnes, T, and Del Duca, GF. Effects of nonperiodized and linear periodized combined training on health-related physical fitness in adults with obesity: a randomized controlled trial. J Strength Cond Res 36(9): 2628-2634, 2022-The aim of this randomized controlled trial study was to compare the effects of 16 weeks of linear periodized and nonperiodized combined training (CT) in cardiorespiratory fitness, muscle strength, and body composition indicators of adults with obesity. Thirty-four obese adults of both sexes (36.6 ± 4.4 years; body mass index, 32.9 ± 2.7 kg·m -2 ) were divided into nonperiodized (NG; n = 8), linear periodized (PG; n = 11), and control (CG; n = 15) groups. The NG and PG groups performed 3 weekly sessions of CT over 16 weeks in different ways. Anthropometric measures, maximal strength for leg press and barbell bench press, maximal oxygen uptake (V̇ o2 max), and ventilatory thresholds were determined before and after intervention. The generalized estimation equation was used, with the applied level of significance for the interaction of 0.10 and the isolated effect of time or group or both of 0.05. Significant and similar increases were observed in the 1-repetition maximum test for bench press (NG: 48.8 ± 5.7 to 55.0 ± 6.1 kg; PG: 48.7 ± 5.7 to 53.8 ± 5.9 kg; p = 0.001) and leg press (NG: 235.2 ± 18.7 to 268.3 ± 19.7 kg; PG: 223.1 ± 25.3 to 253.3 ± 23.1 kg; p = 0.05) in trained groups. Relative V̇ o2 max improved only in PG (27.8 ± 1.3 to 32.0 ± 1.4 mL·kg·min -1 ; p = 0.05), while ventilatory thresholds improved in NG and CG ( p = 0.004 and p = 0.06). There was an increase in body mass in CG (97.6 ± 3.4 to 99.1 ± 2.9 kg) and NG (92.5 ± 5.4 to 93.5 ± 5.4 kg; p = 0.05). Combined training improved maximal upper-body and lower-body strength, regardless of periodization. However, for improvement in V̇ o2 max, linear periodization may be superior to nonperiodization in obese adults.

Resistance Exercise Order Does Not Affect the Magnitude and Duration of Postexercise Blood Pressure in Older Women.

Tomeleri, CM, Nunes, JP, Souza, MF, Gerage, AM, Marcori, A, Iarosz, KC, Cardoso-Júnior, CG, and Cyrino, ES. Resistance exercise order does not affect the magnitude and duration of postexercise blood pressure in older women. J Strength Cond Res 34(4): 1062-1070, 2020-The aim of this study was to compare the effects of 2 resistance exercise order on postexercise blood pressure (BP) in trained nonhypertensive older women. Sixteen women (68.3 ± 3.3 years, 63.5 ± 11.6 kg, 157.5 ± 5.1 cm) performed 2 sessions with 8 exercises (3 sets of 8-12 repetitions) in distinct orders (from multi- to single-joint exercises [MS] or from single- to multijoint exercises [SM]) and a control session (CS), without exercise. Blood pressure and heart rate (HR) were obtained pre- and postsessions (60 minutes). Postexercise hypotension was observed for systolic BP (SBP) and mean BP in both the MS session (SBP: -6.9 mm Hg, mean BP: -3.3 mm Hg, p ≤ 0.05) and SM session (SBP: -4.6 mm Hg; mean BP: -1.1 mm Hg). Postexercise HR was higher than presession values until 30 minutes of recovery in both training sessions. Furthermore, SBP and mean BP, and HR were lower than the values obtained in the CS (30-60 minutes and 0 minutes, respectively; p ≤ 0.05). There were no differences between the SM and MS sessions in any variable or at any moment. In conclusion, resistance exercise order does not interfere in the magnitude and duration of postexercise hypotension in trained nonhypertensive older women.

Physical activity levels and hepatic steatosis: A longitudinal follow-up study in adults.

BACKGROUND AND AIM: This study aimed to evaluate the impact of physical activity (PA) on the course of hepatic steatosis (HS) in adults. METHODS: Hepatic steatosis status (ultrasonography) and PA levels were evaluated in 5860 subjects at baseline and after approximately 2.5 years (range: 19-50 months). At follow up, possible exposures to different PA levels were those who remained inactive, became inactive, became active, and remained active. After follow up, subjects were then classified according to the four possible states (outcomes): "remained without HS," "developed HS" (subjects without HS at baseline), "remained with HS," or "reverted HS." RESULTS: After multivariate adjustments, individuals without HS that became or remained physically active were less likely to develop HS compared with those who remained physically inactive (odds ratio = 0.75, P = 0.04 and 0.75, P = 0.03, respectively). Among those with HS at baseline, becoming and remaining physically active beneficially improved the HS status (odds ratio = 0.64, P = 0.01 and 0.66, P = 0.01, respectively). However, the significance was lost when adjusted for changes in body mass index. CONCLUSION: Higher levels of PA were associated with prevention and treatment of HS, with evidence of effect mediation by changes in body mass index.

Chronic Blood Pressure Reductions and Increments in Plasma Nitric Oxide Bioavailability.

This study analyzed the effects of 12 weeks of resistance training (RT) on resting blood pressure (BP) and plasma levels of nitric oxide metabolites (NOx) in pre- and hypertensive older women, and evaluated the relationship between these 2 parameters. Thirty-five older women (68.2±5.7 years, 70.0±14.4 kg, 157.1±6.4 cm, 28.3±5.0 kg.m-2) were randomly allocated into a training group (TG; n=17), which performed a 12-week RT program, and a control group (CG; n=18), which did not perform any physical exercise. Anthropometry, one repetition maximum (1RM), body composition analysis by dual energy X-ray absorptiometry, blood samples, and resting BP were measured. There was a significant interaction for all variables analyzed, in which reductions of systolic BP (-8.5%), diastolic BP (-8.4%), and mean arterial pressure (-8.5%), and increases of NOx (+35.2%) were observed only for the TG. Moreover, a negative and significant correlation was observed (P<0.05; r=-0.63) between NOx and systolic BP in the TG. Results suggest that a 12-week RT program is sufficient to induce reductions in BP in pre- and hypertensive older women and that the decrease in systolic BP is associated with an increase in plasma NOx concentration.

Long-term creatine supplementation improves muscular performance during resistance training in older women.

This study examined the effects of long-term creatine supplementation combined with resistance training (RT) on the one-repetition maximum (1RM) strength, motor functional performance (e.g., 30-s chair stand, arm curl, and getting up from lying on the floor tests) and body composition (e.g., fat-free mass, muscle mass, and % body fat using DEXA scans) in older women. Eighteen healthy women (64.9 ± 5.0 years) were randomly assigned in a double-blind fashion to either a creatine (CR, N = 9) or placebo (PL, N = 9) group. Both groups underwent a 12-week RT program (3 days week(-1)), consuming an equivalent amount of either creatine (5.0 g day(-1)) or placebo (maltodextrin). After 12 week, the CR group experienced a greater (P < 0.05) increase (Δ%) in training volume (+164.2), and 1RM bench press (+5.1), knee extension (+3.9) and biceps curl (+8.8) performance than the PL group. Furthermore, CR group gained significantly more fat-free mass (+3.2) and muscle mass (+2.8) and were more efficient in performing submaximal-strength functional tests than the PL group. No changes (P > 0.05) in body mass or % body fat were observed from pre- to post-test in either group. These results indicate that long-term creatine supplementation combined with RT improves the ability to perform submaximal-strength functional tasks and promotes a greater increase in maximal strength, fat-free mass and muscle mass in older women.

Familiarization and reliability of one repetition maximum strength testing in older women.

Strength is a fundamental component of physical fitness, and therefore should be precisely assessed. The purpose of this study was to analyze the number of testing sessions required to achieve consistent 1 repetition maximum (1RM) strength measurements in untrained older women. Forty-five untrained older women were measured for 1RM in bench press machine (BP), leg extension (LE) machine, and free weight arm curl (AC). Reliability coefficients for trials 1 and 2 for BP (intraclass correlation coefficient [ICC] = 0.973) and LE (ICC = 0.976) were higher than for AC (ICC = 0.953). Percent change from trial 1 to 2 for BP (3.5 ± 10.9%) and AC (3.8 ± 8.1%) was less than for LE (5.4 ± 6.2%), but all were significant increases between trials (p < 0.05). Trial differences were reduced to nonsignificant levels (p > 0.05) in the third trial for BP (0.0 ± 0.0%), LE (1.2 ± 3.0%) and AC (2.7 ± 5.9%). Reliability coefficients rose for BP and LE (ICC = 0.999) and AC (ICC = 0.963) when a third trial was performed. Bland and Altman plotting showed very small bias and limits of agreement (LoA) for both the exercises (BP: bias = 0 kg, limits of agreement = 0 kg; LE: bias = -0.16 kg, LoA = 2.21 kg; AC: bias = -0.11 kg, LoA = 1.72 kg). This approach to determine 1RM strength values produced rapid lifting technique familiarization resulting in a need of 2 to 3 test sessions to achieve consistent 1RM measurements in untrained older women.

Effects of physical training on functional, clinical, morphological, behavioural and psychosocial outcomes in post-COVID-19 infection: COVID-19 and REhabilitation study (CORE-study)-a study protocol for a randomised controlled clinical trial.

BACKGROUND: The COVID-19 pandemic remains ongoing, with a significant number of survivors who have experienced moderate to severe clinical conditions and who have suffered losses of great magnitude, especially in functional capacity, triggering limitations to daily autonomy and quality of life. Among the possibilities of intervention for disease rehabilitation, physical exercise training stands out, which can benefit several health outcomes and favours the adoption of healthier behaviours. Therefore, the aim of the study will be to analyse the effects of physical training on the functional, clinical, morphological, behavioural and psychosocial status in adults and the elderly following COVID-19 infection. METHODS: A randomised controlled clinical trial is to be conducted in parallel, with the experimental group undergoing an intervention involving a multicomponent physical rehabilitation programme, carried out at the Sports Center in partnership with the Academic Hospital of the Federal University of Santa Catarina, in Florianópolis, Brazil. Participants will be adults and the elderly, of both sexes, in a post-COVID-19-infection state, who were hospitalised during the infection. The intervention will have a total duration of 24 weeks and will include a multicomponent physical training programme, which will have gradual progression in frequency, duration and intensity over time. Regarding the outcomes, before, at the 12th and after 24 weeks of intervention, functional (primary outcome = functional index of aerobic capacity), clinical, morphological, behavioural and psychosocial outcomes will be assessed. DISCUSSION: This study will contribute to a greater understanding of the safety, adherence and benefits of physical training in the rehabilitation of post-COVID-19 patients. The results of this study will be disseminated through presentations at congresses, workshops, peer-reviewed publications and local and international conferences, especially with a view to proposing a post-COVID-19 rehabilitation care protocol. TRIAL REGISTRATION: ReBEC, RBR-10y6jhrs . Registered on 22 February 2022. 2015.

Nine weeks of combined training improve functional and morphological outcomes in trained older people with cardiometabolic risk factors.

BACKGROUND: The study is characterized as a single group experiment, with the aim of verifying the responses of functional capacity and body composition, after a combined training program with undulating periodization, of low cost and easy applicability, in volunteers with cardiovascular risk factors. METHODS: Experimental study carried out with individuals of both sexes, with cardiometabolic risk factors, members of a Cardiorespiratory Rehabilitation Program (PROCOR) of the Federal University of Santa Catarina (UFSC). A combined physical training program (aerobic and strength) with load training progression was used, performed at a frequency of three weekly sessions, on alternate days, for nine weeks and using shin guards, elastic bands or just body weight. Functional capacity, anthropometric profile and body composition of individuals were evaluated before and after the intervention. The comparison of data before and after the intervention period was performed using the Student's t-test for paired samples and the Wilcoxon test. RESULTS: Improvements statistically significant were observed in the tests related to functional capacity, "Sit and Stand", "8-foot-up-and-go" at usual and maximum speeds and "March", along with a decrease in anthropometric measurements of hip circumference, body fat percentage, waist-to-hip ratio, and fat mass in the android region. In addition, the program was well-tolerated with a low rate of sample losses. CONCLUSION: The results of this study suggest that only 9 weeks of combined training at low cost and easy applicability is able to promote improvement in parameters related to functional capacity, anthropometric profile, and body composition of trained older people with cardiovascular risk factors.

Proposition of Cutoff Points for Anthropometric Indicators to Identify High Blood Pressure in Adolescents.

Aim: To propose cutoff points for anthropometric indicators for high blood pressure (HBP) screening in adolescents and to identify, among these indicators, those more accurately for boys and girls. Methods: This cross-sectional study was carried out in the city of São José, SC, Brazil with 634 adolescents aged 14 to 19 years. Blood pressure levels were measured using a digital oscillometric sphygmomanometer and adolescents were classified as having HBP or not. Anthropometric indicators were calculated based on anthropometric measurements such as body mass (BM), height, waist circumference (WC), hip circumference (HC) and triceps, subscapularis, suprailiac, and midcalf skinfold thickness (SF). The Receiver Operating Characteristic Curve (ROC) was used to analyze the predictive capacity of anthropometric indicators in the identification of HBP. Results: Higher values of Area Under the Curve (AUC) were for the anthropometric indicators BM (0.67; 95%CI: 0.62-0.72), body mass index (BMI) (0.67; 95%CI: 0.62-0.72), and WC (0.67; 95%CI: 0.62-0.71) for males. For females, no anthropometric indicator had discriminatory power for HBP screening. The cutoff points for the anthropometric indicators with discriminatory power for HBP screening in males were BM > 64.80 Kg, BMI > 21.76 Kg/m2, fat percentage (FP) > 15.75, waist height to ratio (WHtR) > 0.41, WC > 73.00 cm, and HC > 92.25 cm. Conclusion: Anthropometric indicators of body adiposity had greater discriminatory power of HBP screening in males. For females, caution is suggested because the anthropometric indicators showed AUC values (95%CI) below 0.60.

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 (ß: -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.

Active commuting among workers in the Southern of Brazil: a comparative analysis between 2006 and 2016.

This article aims to compare the prevalence of active commuting to work in adults in the Southern region of Brazil between 2006 and 2016 according to sociodemographic and labor characteristics. The data from the Brazilian System for the Surveillance of Risk and Protection Factors for Chronic Diseases - VIGITEL were compared in 2006 and 2016 (≥18 years). Active commuting to work, sex, age group, education and job characteristics were collected by telephone survey and transportation in the cities of Florianópolis, Curitiba and Porto Alegre, using absolute and relative frequencies with their respective 95% confidence intervals. Active commuting increased significantly in 2016 compared to 2006. Florianópolis had the highest prevalence in the two years analyzed. In all capitals, there was a significant increase in the prevalence of the outcome, mainly for women, with secondary education and only in Florianópolis for men, with low schooling. The prevalence has also increased for job characteristics in all capitals. Active commuting to work increased significantly among adults living in southern Brazil, with emphasis on Florianópolis. Expanding interventions in this context is a necessity in Brazil.

Combined Training with Aerobic Exercise Performed Outdoors Can Promote Better Blood Pressure and Affective Responses in Individuals with Cardiovascular Risk Factors.

The purpose of the study was to compare the effects of two models of combined training (CT) (aerobic and resistance exercise realized in the same training session), with aerobic training performed in different environments (indoor or outdoor), on blood pressure (BP), heart rate (HR), and affective response in individuals with cardiovascular risk factors. Twenty-six participants were allocated, in a non-randomized design, into CT with aerobic exercise performed indoors (ICT) or outdoors (OCT). Both groups were submitted to three weekly CT sessions, with aerobic exercises performed on ergometers or an athletics track. Before and after nine weeks of training, BP and HR at rest were measured. In the last session of the training, the affective response was collected. The individuals were 65.8 ± 7.8 (ICT) and 67.3 ± 8.2 (OCT) years. Lower values of diastolic BP were observed for the OCT group at post-training (p < 0.001). Moreover, in OCT, a significant inverse correlation was identified between the affective response to training and changes in systolic BP (r = −0.60; p = 0.03) and mean BP (r = −0.62; p = 0.02). In conclusion, CT, with aerobic exercise performed outdoors, seems to be more effective in reducing BP with better affective responses to training.

Effects of aerobic training with and without progression on blood pressure in patients with type 2 diabetes: A systematic review with meta-analyses and meta-regressions.

AIMS: To analyze the effects of aerobic training with and without progression on blood pressure in patients with type 2 diabetes. METHODS: The databases used for the systematic search were PubMed, Cochrane Central, SPORTDiscus and LILACS. Studies which analyzed blood pressure before and after an intervention period of eight or more weeks of aerobic training compared to a control group without training in patients with type 2 diabetes were included. RESULTS: Of the 4186 studies found, 17 clinical trials were included (912 participants). Systolic blood pressure (SBP) decreased after aerobic training with progression (-6.78 mmHg; 95% CI -8.36, -5.19; p < 0.001) and without progression (-8.07 mmHg; 95% CI -9.37, -6.77; p < 0.001). The same happened regarding diastolic blood pressure (DBP), which decreased with aerobic training with progression (-3.10 mmHg; 95% CI -4.90, -1.31; p < 0.001) and without progression (-5.71 mmHg; 95% CI -7.15, -4.28; p < 0.001). CONCLUSION: Aerobic training is effective in reducing blood pressure in patients with type 2 diabetes, regardless of progression in training variables.

Simultaneity of chronic noncommunicable diseases in 2013 in Brazilian state capital cities: prevalence and demographic profile. / Simultaneidade de doenças crônicas não transmissíveis em 2013 nas capitais brasileiras: prevalência e perfil sociodemográfico.

OBJECTIVE: to describe the prevalence and sociodemographic profile of chronic noncommunicable disease (CNCDs) simultaneity in adults and elderly people resident in Brazilian state capital cities. METHODS: Chronic Noncommunicable Disease Risk and Protection Factor Surveillance System Survey 2013; simultaneity was considered to be two or more CNCDs (diabetes mellitus, dyslipidemia, hypertension, and obesity). RESULTS: of the total 52,929 participants, 13.7% of adult participants and 42.9% of elderly participants had CNCD simultaneity; hypertension and diabetes mellitus simultaneity was greater in adults, while hypertension and obesity simultaneity was greater in the elderly; simultaneity was more prevalent in women, in those between 50 and 59 years old, with partners and up to eight years of schooling; the cities with the lowest and highest prevalence in adults were São Luís and Cuiabá, respectively, while in the elderly, the cities were Belém and Manaus, respectively. CONCLUSION: simultaneity was identified nationwide; prevention measures should be directed especially toward treatment of hypertension.

Efficacy of a behavior change program on cardiovascular parameters in patients with hypertension: a randomized controlled trial.

OBJECTIVE: To investigate the efficacy of a behavior change program named Vida Ativa Melhorando a Saúde on cardiovascular parameters in hypertensive patients. METHODS: Ninety hypertensive patients aged over 40 years were randomly allocated to one of two groups: Vida Ativa Melhorando a Saúde or Control (n=45 respectively). Patients in the Vida Ativa Melhorando a Saúde group took part in a behavior change program aimed to encourage changes in physical activity levels and eating habits, according to the Social Cognitive Theory. The program consisted of 90-minute weekly group meetings conducted by a physical therapist and a dietitian. One chapter of the educational material (workbook) provided was discussed per meeting. Participants in the Control Group attended a single educative lecture on lifestyle changes. Brachial and central blood pressure, arterial stiffness and endothelial function parameters were measured pre- and post-intervention. RESULTS: Vida Ativa Melhorando a Saúde led to reduction of brachial (131.3±15.8mmHg to 125.1±17.3mmHg; p<0.01) and central (123.6±16.3mmHg to 119.0±20.6mmHg; p=0.02) systolic and brachial diastolic (123.6±16.3mmHg to 119.0±20.6mmHg; p<0.01) blood pressure values, and improvement of post-occlusive reactive hyperemia (from 5.7±2.5mL·100mL-1 to 6.5±2.1mL·100mL-1 tissue·min-1; p=0.04). No changes in body composition, heart rate and arterial stiffness parameters were detected in both groups (p>0.05). CONCLUSION: Vida Ativa Melhorando a Saúde program improved blood pressure and microvascular reactivity in hypertensive patients. Trial registration: ClinicalTrials.gov: NCT02257268.

Evaluation of the Omron MX3 Plus monitor for blood pressure measurement in adolescents.

This study analyzed the accuracy/agreement of the Omron MX3 monitor on 165 adolescents. Blood pressure was measured by the automatic monitor connected in Y with the mercury column (three consecutive and simultaneous measures). The independent measures were analyzed, and the mean differences between systolic and diastolic measures for both methods were calculated and compared with British Hypertension Society (BHS) and Association for the Advancement of Medical Instrumentation (AAMI) criteria. The automatic monitor received the highest degree of BHS recommendations for systolic and diastolic blood pressures according to the BHS. The median (25th and 75th) difference between the observer and the monitor measurements was -2 (-6 and 1) mmHg for systolic and 0 (-3 and 1) mmHg for diastolic pressures. The monitor also satisfies the AAMI standard for the studied population. In conclusion, the Omron MX3 Plus monitor can be considered reliable and valid for clinical practice and is in accordance with BHS and AAMI criteria.

Comparison of linear periodized and non-periodized combined training in health markers and physical fitness of adults with obesity: Clinical trial protocol.

The literature discusses that combined training, aerobic more resistance exercises in the same session, is a suitable strategy for people with obesity and that exercise periodization leads to positive health outcomes; however, the implication of different periodizations of combined training for health outcomes in obese adults requires further investigation. The aim of the study will be to describe the methodology used to compare the effect of linear periodized and non-periodized combined training on health markers and health-related physical fitness in adults with obesity. This is a blinded randomized controlled clinical trial investigating adults with obesity in the age group 20-50 years. The sample will be non-probabilistic, and participants will be allocated randomly into one of three groups: control group (CG), non-periodized group (NG), and periodized group (PG). The intervention will occur in 60-min sessions, 3 days a week for 16 weeks, with 1 week dedicated to familiarization with the training and 15 weeks of combined training (aerobic followed by resistance in the same session). The PG group will perform three mesocycles of 5 weeks each, progressing in intensity throughout the intervention [aerobic: from 40-49% to 60-69% of heart rate reserve (HRR); strength: from 12 to 14 maximum repetitions (MR) to 8 to 10MR]; the NG group will maintain the same relative intensity throughout the study (aerobic: 50-59% of HRR; strength: 2 sets of 10-12 MR). Participants in the CG group will maintain their usual activities without the proposed intervention. Pre- and post-intervention assessments will be performed for biochemical markers, body composition, cardiovascular parameters, cardiorespiratory fitness, maximum upper and lower limb strength, flexibility, and subjective health-related parameters. This project was approved by the Committee of Ethics and Research with Human Beings of the institution of origin (protocol 2,448,674) and registered in the Brazilian Registry of Clinical Trials (RBR-3c7rt3).

Barriers to physical activity practice and associated factors in patients with hypertension / Barreiras para a prática de atividade física e fatores associados em pacientes com hipertensão arterial

Abstract The identification of barriers to regular physical activity (PA) is a form of an initial and effective strategy to encourage behavior modification and adherence to a more active lifestyle in hypertensive patients. This cross-sectional study aimed to identify the barriers to PA practice in patients with hypertension classified as physically inactive and to analyze the association of the number of these barriers with sociodemographic factors and health indicators. Two hundred one hypertensive patients of both sexes (61.7±12.7 years) answered an anamnesis with health information and sociodemographic data, a PA level questionnaire, and a barrier questionnaire for the practice of PA. Regarding the level of PA of the participants, 48.8% were classified as physically inactive and reported, on average, 6.1 (±3.8) barriers to PA practice, with the barrier "fear of falling or getting hurt" the most commonly reported. Furthermore, women and patients with low education, negative perception of health, and a greater presence of comorbidities reported a greater number of barriers to PA practice. PA practice as a non-pharmacological tool for the treatment of hypertension should focus on women and patients with low education, negative perception of health, and a greater presence of associated comorbidities.

Resumo A identificação de barreiras à atividade física regular (AF) é uma forma de estratégia inicial e eficaz para encorajar a modificação do comportamento e a adesão a um estilo de vida mais ativo em pacientes hipertensivos. Este estudo transversal visou identificar as barreiras à prática de AF em pacientes com hipertensão classificados como fisicamente inativos e analisar a associação do número destas barreiras com fatores sociodemográficos e indicadores de saúde. Duzentos e um pacientes hipertensos de ambos os sexos (61.7±12.7 anos) responderam a uma anamnese com informações de saúde e dados sociodemográficos, um questionário de nível de AF, e um questionário de barreira para a prática de AF. Relativamente ao nível de AF dos participantes, 48,8% foram classificados como fisicamente inativos e reportaram, em média, 6,1 (±3,8) barreiras à prática de AF, sendo a barreira "medo de cair ou de se magoar" a mais frequentemente reportada. Além disso, mulheres e pacientes com baixa educação, percepção negativa da saúde, e uma maior presença de comorbidades reportaram um maior número de barreiras à prática de AF. A prática de AF como ferramenta não farmacológica para o tratamento da hipertensão deve ter como foco mulheres e pacientes com baixa escolaridade, percepção negativa de saúde e maior presença de comorbidades associadas.
