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.

Book Description
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.

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

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

Book Description
Endothelial dysfunction, or the inability of an artery to dilate sufficiently when subjected to excessive shear stress, serves both as a predictor of future cardiovascular events as well as an early indication of atherosclerosis. Several chronic disease states, including obesity, have been shown to alter endothelial function, which may be mediated through circulating pro- and anti-inflammatory adipokines. Still, the mechanisms by which obesity-related low-grade inflammation alters endothelial function are not fully elucidated. Acute and chronic endurance exercise training has previously been shown to be effective in improving endothelial function; however, chronic resistance exercise training is not universally regarded as beneficial to vascular functioning. Far fewer studies have examined the effect of acute resistance exercise on vascular function and adipokine release. To further understand the effects of resistance exercise training on vascular function, a meta-analysis was completed to examine the effects of resistance training on brachial artery flow mediated dilation (FMD), a common measure of endothelial function. The results of the meta-analysis indicate that resistance training has a small positive effect on FMD. Additionally, the effects of an acute bout of lower body resistance exercise on forearm blood flow (FBF) and two inflammatory cytokines were evaluated in obese (>30% body fat) and non-obese ([less or equal to] 30% body fat) subjects. It was hypothesized that the resistance exercise bout would increase FBF, that those changes would be greater in obese versus non-obese subjects, and that the changes in circulating cytokines (adiponectin and tumor necrosis factor-[alpha]) would be related to changes in FBF. The results indicate that FBF measures in obese and non-obese subjects react in a divergent pattern immediately following resistance exercise but return to baseline within 24 hours. These changes were not related to changes in adiponectin or TNF-[alpha] although changes in adiponectin were related to changes in TNF-[alpha]. In conclusion, resistance exercise training programs may have a small positive effect on vascular function which may reduce overall cardiovascular disease risk. Additionally, obese and non-obese subjects display differing patterns of vascular responses to an acute bout of resistance exercise, supporting the view that obesity, and its associated low-grade inflammatory response, may negatively alter vascular homeostasis.

Book Description
In this comprehensive handbook, Ragin and Keenan present an all-encompassing analysis of the variety of different methods used in health psychology research. Featuring interdisciplinary collaborations from leading academics, this meticulously written volume is a guide to conducting cutting-edge research using tested and vetted best practices. It explains important research techniques, why they are selected and how they are conducted. The book critically examines both cutting-edge methods, such as those used in NextGen genetics, nudge theory, and the brain’s vulnerability to addiction, as well as the classic methods, including cortisol measurement, survey, and environmental study. The topics of the book span the gamut of health psychology field, from neuroimaging and statistical analysis to socioeconomic issues such as the policies used to address diseases in Africa, anti-vaxers, and the disproportionate impact of climate change on impoverished people. With each section featuring examples of best research practices, recommendations for study samples, accurate use of instrumentation, analytical techniques, and advanced-level data analysis, this book will be an essential text for both emerging student researchers and experts in the field and an indispensable resource in health psychology programs.

Book Description
In patients with type 2 diabetes (DM2) arterial stiffness, heart rate variability (HRV), high sensitivity C-reactive protein (hs-CRP) and hyperaemic calf blood flow were measured before and after 12 weeks of combined aerobic and resistance exercise training. Arterial stiffness and HRV were also measured after 20 minutes of moderate, aerobic exercise pre and post exercise training. A single acute bout of aerobic exercise results in significantly elevated central arterial stiffness both before and after 12 weeks of training whereas AAI is reduced prior to training only. After 12 weeks of training, significant improvements were found in: C-F PWV (p=0.026); augmentation index (p= 0.005); peak oxygen uptake (p=.002) fasting plasma glucose (p=0.041), abdominal circumference (p=0.001), BMI (p=0.004) and body fat (p=0.032). Improvements in arterial stiffness were not associated with any change in anthropometric measurements, aerobic fitness, hs-CRP or indices of heart rate variability.
