This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black populations account for the highest rates of cardiovascular disease (CVD) mortality, morbidity, and subclinical indices of CVD. Studies support that there are ethnic disparities in arterial stiffness, particularly manifested as early vascular aging. While ethnic disparities cannot be solely explained by traditional CVD risk factors, psychosocial factors, such as mental stress, have correlated to increased arterial stiffness. Exercise has been mentioned as a notable therapeutic mechanism for stressrelated stiffness. Thus, the purpose of this study was to determine the effects of an acute bout of moderate-intensity aerobic exercise on mental stress-induced arterial stiffness in Black young adults. METHODS: 10 apparently healthy individuals (4 male, 6 female, 22.0 ± 1.8 years and BMI 25.3 ± 3.6 kg/m2) performed 30 minutes of treadmill exercise at 64-76% of heart rate maximum before a 5-minute mental stress task. Arterial stiffness (measured as carotid femoral pulse wave velocity [cfPWV]) and brachial and central hemodynamic measures (bSBP, bDBP, bPP, cSBP, cDBP, cPP, MAP, HR, AP, AIx, AIx@75) were recorded before and after the task and compared to results gathered on the control day (consisting of the same mental stress task without prior exercise). Participants were randomly assigned to either the control or exercise trial first. RESULTS: The mental stress task increased PWV, independent of exercise (main effect for time, p 0.001). The absolute change in PWV from pre to post 0 minutes was similar (p 0.05) for control (+0.43±0.39) and exercise (+0.33±0.70) trials. Mental stress had a main effect for time (p

This book was released on 2012 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arterial stiffness increases cardiovascular disease risk for stroke, myocardial infarction, and mortality. The aim of this study was to examine the influence of resistance exercise intensity on arterial stiffness and blood pressure. Two resistance exercise conditions, low and high intensity, were compared. In a longitudinal, cross-over study design, thirty-two subjects (n=32, 17 male, mean age= 24.6) completed both conditions on separate days. Pulse wave velocity (PWV) was used as a measure of central and peripheral arterial stiffness at baseline, at 15 minutes post, and at 30 minutes post exercise. Central PWV increased in the low mode and returned toward baseline at 30 minutes post-exercise (p

This book was released on 2011 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The investigation was designed to determine the effect of moderate and high intensity resistance exercise (RE) on arterial stiffness (AS) . Subjects consisted of young healthy males who regularly resistance trained (N = 12) Each subject completed both the moderate and high intensity bouts in a randomized order. Pulse wave velocity (PWV) was used to estimate AS and was measured at baseline, 10 mm post, 20 mm post, and 30 mm post. Heart rate (HR) was measured during each bout to serve as a marker of sympathetic nervous system activity. A total body RE workout was completed during each bout and consisted of four free weight exercises. Significant increases (p

Available in PDF, EPUB and Kindle. Book excerpt: As the first primer on the effects of exercise on human hypertension, Effects of Exercise on Hypertension: From Cells to Physiological Systems provides the state-of-the-art effects of exercise on the many possible mechanisms underlying essential hypertension in humans. The book contains chapters by distinguished experts on the effects of exercise on physiological systems known to be involved in hypertension development and maintenance as well as less well known aspects of hypertension such as 24-hour ambulatory blood pressure profile and oxidative stress. An emerging area, the effects of resistance exercise training on blood pressure is also covered. A unique aspect of the book is that it covers the effects of exercise mimetics on vascular cell adaptations in order to begin to elucidate some of the cellular mechanisms that may underlie blood pressure reductions with exercise training. Lastly, the book will end with a chapter on the interactive effects of genes and exercise on blood pressure. Chapters are grouped by physiological system or mechanism. The text begins with two overview chapters; one on the general effects of aerobic exercise training and the second on the general effects of resistance exercise training on blood pressure. Each chapter begins with a bulleted list of key points. Effects of Exercise on Hypertension: From Cells to Physiological Systems will be of great value to professional individuals in cardiovascular medicine, the cardiovascular sciences, allied health care professionals, and medical and graduate students in the cardiovascular sciences and medicine.

This book was released on 2021 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Elevated arterial stiffness has been recognized as an independent risk factor for cardiovascular disease and has been associated with long-term worse clinical outcomes in several populations. The purpose of this study was to investigate the effects of gender and time following one acute bout of moderate intensity resistance exercise on arterial stiffness in college-aged men and women. A total of 26 men (n = 14) and women (n = 12) completed three sessions: screening, familiarization, and testing in the order they are listed. There were no changes in pulse wave velocity or augmentation index in either men or women across time. Men did have significantly higher systolic blood pressure at baseline (p = .00, d =1.4), immediately post exercise (p = .01, d = 1.0) and 30 minutes post exercise (p = .04, d = .08) relative to women. Men also had significantly higher heart rates immediately post exercise (p = .02, d = 0.9) and 30 minutes post exercise (p = .04, p = 0.9) when compared to women. The lack of change in parameters of arterial stiffness suggest moderate intensity exercise does not increase arterial stiffness in college-aged adults.

This book was released on 2020 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity is a major risk factor for cardiovascular disease (CVD), CVD mortality, and type 2 diabetes. Arterial stiffness and autonomic dysfunction are independent predictors of CVD and type 2 diabetes. Moreover, African Americans (AA) have a disproportionate prevalence of elevated arterial stiffness compared to Caucasians. Obese individuals have a greater prevalence of diminished autonomic nervous system activity compared to lean individuals. Despite evidence of aerobic exercise training benefiting arterial stiffness and autonomic dysfunction in the general population, optimal intensity and volume for AAs and obese individuals remain unclear. The purpose of this dissertation was to determine whether high-intensity aerobic exercise training improved arterial stiffness and aortic compliance to a greater degree than moderate intensity in obese AAs (study 1), if clinically significant weight loss from a combined hypocaloric diet and aerobic exercise intervention increases heart rate variability (HRV) in obese adults and to evaluate the impact of aerobic exercise volume on HRV during weight maintenance (study 2). Arterial stiffness or aortic compliance did not improve in response to 24 weeks of moderate- or high-intensity, supervised aerobic exercise training at a volume consistent with public health guidelines. However, both groups significantly increased cardiorespiratory fitness compared to the control group. In addition, we observed an inverse relationship between changes in cardiorespiratory fitness and aortic compliance. The results from this study suggest AAs may require greater volumes of weekly aerobic exercise than recommended for the general population to improve arterial stiffness. The 10-week, combined intervention improved major HRV indices of parasympathetic activity. The changes in parasympathetic activity were inversely associated with fasting insulin concentrations. Both groups retained all HRV benefits over the 18-week maintenance phase. The results from this study suggest weight loss via energy restriction and exercise alter autonomic function, leading to improved sympathovagal balance in obese adults, also exercise volumes consistent with physical activity guidelines maintains improvements in autonomic function from weight loss. Collectively, the results of this dissertation provide valuable public health insight for health professionals prescribing aerobic exercise to improve predictors of CVD and type 2 diabetes, specifically arterial stiffness, aortic compliance, and autonomic dysfunction in at-risk, obese adults.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Cardiovascular disease (CVD) is the leading cause of death globally. One of the most effective forms of prevention and treatment is physical activity. However, recent studies have suggested that resistance exercise can increase arterial stiffness. Maintaining adequate strength is critical for performing activities of daily living, occupational-related tasks, and sport movements. The purpose of this project was to determine if novel combinations of resistance and aerobic exercise could offer musculoskeletal benefits without adverse cardiovascular consequences. In Study 1, we examined the effect of order (i.e. aerobic before resistance, or resistance before aerobic) on arterial stiffness when combining these exercise modes in a single training session. In Study 2, we compared the effects of acute eccentric and concentric arm cycling on central and peripheral arterial stiffness. Eccentric arm cycling is a unique combination of resistance and aerobic exercise. We hypothesized that these novel combinations of resistance and aerobic exercise would not cause arterial stiffening as observed in resistance exercise alone. In Study 1, we concluded performing resistance before aerobic to be the more beneficial exercise order in terms of arterial stiffness. In Study 2, we found that eccentric arm cycling reduces arterial stiffness in the arm, but not centrally. Collectively, our results suggest that the key to reducing the negative effects of resistance exercise on arterial function is to combine it with aerobic exercise, either first within a single session or simultaneously.
