Filter by:The investigators aim to determine the association of dietary intake on cardiovascular disease risk factors among children with overweight and obesity who are being evaluated for elevated blood pressure. The investigators will also investigate for predictors of vascular function and determine if predictors vary by level of sodium intake.
The purpose of this study was to examine the impact of a 12-week jump rope exercise program on body composition, blood pressure, insulin resistance, and academic self-efficacy in prehypertensive adolescent obese girls. Forty-eight prehypertensive adolescent obese girls participated in this study. The girls were randomly divided into the jump rope exercise intervention group (EX, n=24) and control group (CON, n=24). The EX group performed a jump rope training program at 40-70% of their heart rate reserve (HRR) 5 days/week for 12 weeks (sessions 50 minutes in duration). The CON group did not participate in any structure or unstructured exercise protocol. Blood pressure, body fat percentage, waist circumference, blood glucose and insulin, homeostatic model assessment - insulin resistance, and Academic Self-Efficacy were measured before and after the 12-weeks study.
The primary aim is to identify the impacts of a behavioral intervention called "Mindfulness-Based Blood Pressure Reduction" (MB-BP) vs. enhanced usual care on the primary self-regulation target, specifically an assay of self-related processes (Multidimensional Assessment of Interoceptive Awareness) (MAIA) at 6 months, via a randomized controlled trial.
Traditional medical treatments are often based on research done exclusively in males, and recent research efforts in the physiology community have highlighted critical sex differences in disease presentation and progression. For example, the relative risk of fatal heart disease is 50% greater in obese, diabetic women as compared to their male counterparts, and women appear to respond differently to lifestyle interventions such as exercise compared with men. Chronic passive heat exposure (hot tub use) provides alternative or supplemental therapeutic potential for improving cardiovascular and metabolic health in obese women. In addition, passive heat exposure may offer specific cellular protection from stresses like a lack of blood flow (ischemia), which is the primary cause of fatal coronary heart disease. This study is investigating the possible cardiovascular and metabolic health benefits of chronic passive heat exposure, and whether regular hot tub use (3-4 days per week for 8-10 weeks) may reduce obese womens' cardiometabolic risk. The investigators are examining cardiovascular health through blood pressure, blood vessel stiffness, sympathetic ('fight or flight') activity, and responsiveness to stresses like increased or decreased blood flow. The investigators are also examining metabolic health through an oral glucose tolerance test and a subcutaneous fat biopsy. The goal of this research is to develop a therapy targeted toward the specific health needs and complications of obese women, in an effort to improve cardiovascular and metabolic health and provide therapeutic alternatives in this high-risk population.
The purpose of this study was to examine the impact of a 12-week jump rope exercise program on blood pressure, arterial stiffness, vasodilating and vasoconstricting factors, inflammatory markers, and body composition in prehypertensive adolescent girls. Forty prehypertensive adolescent girls participated in this study. The girls were randomly divided into the jump rope exercise intervention group (EX, n=20) and control group (CON, n=20). The EX group performed a jump rope training program at 40-70% of their heart rate reserve (HRR) 5 days/week for 12 weeks (sessions 50 minutes in duration). The CON group did not participate in any structured or unstructured exercise protocol. Blood pressure, arterial stiffness, plasma nitrate/nitrite levels, endothelin-1, C-reactive protein, and body composition were measured before and after the 12-weeks study.
This study was a randomized controlled trial study. The aim of this study was to determine the effect of soursop fruit supplementation on blood pressure (BP), serum uric acid (SUA), and kidney function. The definition of prehypertension and hypertension was accepted as delivered in The Seventh Report of the Joint National Committee (JNC 7) as the systolic BP was 120 - 139 mmHg and diastolic BP was 80 - 89 mmHg for prehypertension, while systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg for hypertension. Based on the study by Sja'bani (2014), the cut-off point of (SUA) was divided into 3 categories, which are normal (< 5 mg/dL), high-normal (5 - <7 mg/dL), and high (≥ 7 mg/dL). A number of 143 people with essential prehypertension and high normal uric acid level were assigned as subject in this study. Subjects were randomly assigned into two groups which are treatment and control group. For a 3 months period, the treatment group was given 2x100 g soursop fruit juice per day and the control group was left without treatment. Blood pressure was measured by medical team using Omron HEM-907 (digital automatic blood pressure monitoring) every 2 weeks (3 times readings for each) in each subject's home. Subjects were examined in sitting position. Evaluation of laboratory examination was taken at week 0, 7 and 13.
Aronia berries are a native North American berry with high naturally occurring anthocyanins among other polyphenols. Based on their polyphenol composition, there is growing interest in the potential for Aronia berries to elicit health promoting cardio-metabolic effects. Specifically, Aronia berry extracts, which provide a concentrated source of polyphenols, may improve blood vessel function. Thus, the primary focus of this project is to evaluate the effects of Aronia berry polyphenols on blood pressure and other biomarkers of cardiovascular disease risk such as endothelial function, arterial stiffness and blood lipids.
The prevalence of pre-hypertension and hypertension in the elderly is very high. Apart from medication, physical exercise training is a potential strategy to reduce blood pressure, however, the ability to perform exercise can be limited in the elderly. Hence, alternative non-pharmacological strategies to reduce blood pressure are necessary. Two interventions that have been shown to positively influence blood pressure are respiratory muscle training (RMT) and intermittent hypoxia (IH). Whether a combination of RMT and IH yields even better effects is currently unknown. Therefore, in this study, the effect of a single session of RMT with and without IH on blood pressure and associated cardiovascular parameters will be investigated in elderly subjects with pre-hypertension.
This is a 2-arm, 3-month randomized trial comparing a novel sedentary behavior intervention vs. control in working adults (n=300). The primary outcome is resting systolic blood pressure (SBP) at 3 months; secondary outcomes will be resting diastolic blood pressure (DBP), ambulatory blood pressure (ABP), and carotid-femoral pulse wave velocity (cfPWV). Also, best practice objective activity monitoring will be leveraged in the analysis of ABP to account for recent activity and posture and will inform adherence and dose-response relationships.We will also measure plasma renin activity and aldosterone as a potential mechanism of blood pressure reduction, and insulin and glucose as exploratory outcomes.
The purpose of this study is to assess the efficacy of inspiratory muscle strength training for lowering blood pressure and improving physiological function (vascular, motor, and cognitive) in middle-aged and older adults with elevated systolic blood pressure.
