BACKGROUND: The prevalence of hypertension increases with age, more than 1 in every two elderly have hypertension, dominated by women. The primary prevention of hypertension is a worldwide public health concern. Salat Dhuha is a moderate-intensity physical activity. Salat with a two-movement cycle (rakaat) demonstrated improved hemodynamic in adults. AIM: Our study purpose was to asses the effects of 2 and 8 rakaats of Salat Dhuha in improving systolic and diastolic blood pressure and heart rate in healthy elderly women. METHODS: Elderly women in the Senior Care Residence (aged 60–74 years) participated in a 6-week controlled study. We completed a formal physical, clinical, and blood assessments before admission. Participants with a history of hypertension were excluded from the study. The participants were randomized into 2 groups, i.e., “8 rakaats group” (n = 13) and “2 rakaats group” (n = 13) of Salat Dhuha. Two participants dropped out from the present study. At baseline and at the end of 6 weeks study period, blood pressure and heart rate were recorded. All data obtained were statistically analyzed. RESULTS: Both groups demonstrated the benefits of Salat Dhuha in improving hemodynamic parameters (systolic and diastolic blood pressure and heart rate). However, the reduction of systolic blood pressure in the “2 rakaats group” (2.16 mmHg) was less than in the “8 rakaats group” (5.50 mmHg), the reduction of diastolic blood pressure in the “2 rakaats group” (0.75 mmHg) was less than the “8 rakaats group” (2.41 mmHg) and the reduction of heart rate in “2 rakaats group” (2.08 bpm) was less than the “8 rakaats group” (6.08 bpm). All differences were statistically significant (p < 0.05). CONCLUSION: This study demonstrated that the Salat Dhuha has a significant potential in improving hemodynamic parameters for elderly women which the more frequent rakaat will give more benefit than less frequent rakaat.

AbstractTo track blood pressure (BP) and resting heart rate (RHR) in children and adolescents is important due to its associations with cardiovascular outcomes in the adulthood. Therefore, the aim of this study was to examine BP and RHR over a decade among children and adolescents living in Germany using national examination data. Cross-sectional data from 3- to 17-year-old national survey participants (KiGGS 2003–06, n = 14,701; KiGGS 2014–17, n = 3509) including standardized oscillometric BP and RHR were used for age- and sex-standardized analysis. Measurement protocols were identical with the exception of the cuff selection rule, which was accounted for in the analyses. Different BP and RHR trends were observed according to age-groups. In 3- to 6-year-olds adjusted mean SBP and DBP were significantly higher in 2014–2017 compared to 2003–2006 (+2.4 and +1.9 mm Hg, respectively), while RHR was statistically significantly lower by −3.8 bpm. No significant changes in BP or in RHR were observed in 7- to 10-year-olds over time. In 11- to 13-year-olds as well as in 14- to 17-year-olds lower BP has been observed (SBP −2.4 and −3.2 mm Hg, respectively, and DBP −1.8 and −1.7 mm Hg), while RHR was significantly higher (+2.7 and +3.7 bpm). BP trends did not parallel RHR trends. The downward BP trend in adolescents seemed to follow decreasing adult BP trends in middle and high-income countries. The increase in BP in younger children needs confirmation from other studies as well as further investigation. In school-aged children and adolescents, the increased RHR trend may indicate decreased physical fitness.

ABSTRACTRegular exercise induces a broad spectrum of adaptation reactions in a variety of tissues and organs. However, the respective mechanisms are incompletely understood. In the context of their analysis, animal model systems, specifically rodent treadmill running protocols, play an important role. However, few researchers have studied different aspects of adaptation, such as cardiorespiratory and skeletal muscle training effects, within one set of experiments. Here, we analyzed physiological adaptation to 10 weeks of regular, moderate-intensity, uphill treadmill running in mice, a widely used model for endurance exercise training. To study the effects of reactive oxygen species (ROS), which have been suggested to be major regulators of training adaptation, a subgroup of mice was treated with the ROS scavenger PDTC (pyrrolidine dithiocarbamate). We found that mass gain in mice that exercised under PDTC treatment lagged behind that of all other experimental groups. In addition, both exercise and PDTC significantly and additively decreased resting heart rate. Furthermore, there was a trend towards an enhanced proportion of type 2A skeletal muscle fibers and differential expression of metabolism-associated genes, indicating metabolic and functional adaptation of skeletal muscle fibers. By contrast, there were no effects on grip strength and relative mass of individual muscles, suggesting that our protocol of uphill running did not increase skeletal muscle hypertrophy and strength. Taken together, our data suggest that a standard protocol of moderate-intensity uphill running induces adaptation reactions at multiple levels, part of which might be modulated by ROS, but does not enhance skeletal muscle hypertrophy and force.

AbstractThe effects of 16 weeks at sea upon selected parameters of health and physical fitness were investigated in 30 male volunteers (from a total crew of 48 men) prior to, and immediately following deployment. The 30 subjects were assigned toeither an exercise group, ‘Ex’ (n=12), or a non-exercising group, ‘Nil ex ’ (n = 18), according to their reported participation in vigorous training or sports. Body mass index (BMI), calculated from height and weight, revealed that prior to deployment 13 of the 30 subjects (two in the Ex group) had a BMI over 25 kg.m−2 (i. e. overweight), and a further three subjects (all ‘non-exercisers’) had values of 30 kg.m−2 or more (obese). In addition, the diastolic blood pressure of two subjects was in excess of 95 mmHg and five subjects had resting heart rates above 89 beats per minute. Retrospective comparisons between the Ex and Nilex groups revealed a significantly lower percentage body fat (P<0.01) and a faster rate of cardiac recovery (P<0.05) following a standardised bout of exercise in the Ex group, albeit that these individuals were significantly younger (mean age of 24 years) than those in the Nilex group (32 years). Following deployment, in the Nilex group, comparisonof pre- and post values showed that resting heart rate was elevated (P<0.01) on return from sea. Similarly, in the Nilex group heart rate while performing the standardised exercise about was also elevated (P<0.05) on the second test occasion. In the Ex group, heart rate measures during and foJlowing exercise indicated a significantly slower rate of recovery (P<0.05) on the second test occasion.

Cardiometabolic Traits

Abstract Objectives To examine the direction, strength and causality of the associations of resting heart rate (RHR) with cardiometabolic traits. Methods We assessed the strength of associations between measured RHR and cardiometabolic traits in 506,211 and 372,452 participants from China Kadoorie Biobank (CKB) and UK Biobank (UKB). Mendelian randomization (MR) analyses were used to make causal inferences in 99,228 and 371,508 participants from CKB and UKB, respectively. Results We identified significant, directionally-concordant observational associations between RHR and higher total cholesterol, triglycerides (TG), low-density lipoprotein, C-reactive protein (CRP), glucose, body mass index, waist-hip ratio (WHR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) after the Bonferroni correction. MR analyses showed that 10 beat/min higher genetically-predicted RHR were trans-ethnically associated with a higher DBP (beta 2.059 [95%CI 1.544, 2.574] mmHg in CKB; 2.037 [1.845, 2.229] mmHg in UKB), higher CRP (0.180 [0.057, 0.303] log mg/L in CKB; 0.154 [0.134, 0.174] log mg/L in UKB), higher TG (0.052 [-0.009, 0.113] log mmol/L in CKB; 0.020 [0.010, 0.030] log mmol/L in UKB) and higher WHR (0.218 [-0.033, 0.469] % in CKB; 0.225 [0.111, 0.339] % in UKB). In the opposite direction, higher genetically-predicted SBP, TG, glucose, WHR and lower high-density lipoprotein were associated with elevated RHR. Conclusion Our large-scale analyses provide causal evidence between RHR and cardiometabolic traits, highlighting the importance of monitoring heat rate as a means of alleviating the adverse effect of metabolic disorders.

We investigated why resting heart rate is elevated in dogs fed a high saturated fat diet for 12.7 +/- 1.8 wk. Obese dogs exhibited elevated body weight (59%), blood pressure (14%), and heart rate (25%). Differences in resting heart rate (control, 58 +/- 5 beats/min; obese, 83 +/- 7 beats/min) were abolished after hexamethonium, indicating an autonomic mechanism. Hexamethonium also reduced blood pressure in obese (20 +/- 4 mmHg) but not control (9 +/- 6 mmHg) animals. Propranolol did not affect heart rate in either group, excluding a beta-adrenergic mechanism. Subsequent administration of atropine increased heart rate more in control than in obese dogs (110 +/- 9 vs. 57 +/- 11 beats/min). The sensitivity of the cardiac limb of the baroreflex (Oxford method) was reduced by 46% in the obese group, confirming impairment of the parasympathetic control of heart rate. The standard deviation of blood pressure measurements was normal when expressed as a percentage of the mean arterial blood pressure (control, 11.2 +/- 0.4%; obese, 11.2 +/- 0.5%). Our results indicate that the development of obesity in dogs fed a high saturated fat diet is accompanied by an attenuated resting and reflex parasympathetic control of heart rate.

Background Impaired sleep quality is commonplace within industrialized societies, as evidenced by the increasing number of prescription sleep aids available. Certain herbal preparations have been suggested to provide a natural benefit to sleep; however, limited controlled data are available documenting this benefit. In the present study we tested the effect of an experimental dietary supplement, containing the active ingredients Chlorophytum borivilianum and Velvet bean, on sleep quality using the Pittsburgh Sleep Quality Index (PSQI). Methods Eighteen healthy and active men and women, with evidence of impaired sleep quality, consumed the supplement daily for 28 days. The PSQI was administered before and after the intervention period. As indicators of safety, resting heart rate and blood pressure were measured, and a complete blood count, comprehensive metabolic panel, and lipid panel were determined. Results Sleep quality was influenced by the supplement, as evidenced by an improvement in every category of the PSQI questionnaire ( P < 0.05), with most category scores improving approximately 50% from pre to post intervention. No adverse outcomes were noted with use of the supplement, as indicated by no change in resting heart rate, blood pressure, or any bloodborne parameter. Conclusions An investigational dietary supplement containing the active ingredients Chlorophytum borivilianum and Velvet bean improves sleep quality in men and women. Additional placebo controlled trials are needed to corroborate these findings in individuals with self-reported sleeping difficulty.

Abstract Background/Introduction Elevated resting heart rate (RHR) is a known risk factor for HF. Whether elevated RHR is also associated with cardiomyopathy (CM), a common cause of heart failure in the young, is unknown. Purpose To investigate the association of resting heart rate (RHR) measured in late adolescence with long term risk of various subtypes of CM with special attention to cardiorespiratory fitness (CRF), an important predictor of RHR and myocardial dysfunction. Methods We followed a cohort of Swedish men enrolled for conscription in 1968–2005 (n=1,008,485; mean age=18.3 years) until December 2014. Outcomes of CM were collected from the national inpatient- (IPR), outpatient- (OPR) and cause of death registries and were divided into categories: 1) dilated, 2) hypertrophic, 3) alcohol/drug-induced, and 4) other. Cox proportional hazard models were used to analyze the longitudinal association between RHR and outcomes while adjusting for potential confounders, including body mass index (BMI), arterial blood pressure and cardiorespiratory fitness (CRF). CRF was measured by maximum capacity ergometer testing as part of the enlistment protocol. Results During a mean follow up of 34 years, there were 3500 cases of a first hospitalization for CM (mean age at diagnosis, 50.1 years). Comparing the highest with the lowest quintile of the RHR distribution, we found a positive association between RHR and dilated CM (hazard ratio (HR) = 1.58 [confidence interval (CI) = 1.37–1.82]) after adjustment for BMI, age at conscription, conscription year, test center, and baseline comorbidities (diabetes, hypertension, congenital heart disease). There no significant association with alcohol/drug-induced (HR=1.32 [CI=0.94–1.85]) or other categories of CM. Conclusion Adolescent RHR is associated with future risk CM, independently of blood pressure, BMI and CRF. The association was driven by dilated CM. These findings are suggestive of a causal pathway between elevated heart rate and adverse cardiac remodeling that warrants further investigation.
