Book Description
Abstract: Exercise training has consistently been shown, in the research literature, to be an effective non-pharmacological alternative to treat hypertension (HTN). However, the underlying mechanism that accounts for the reductive and preventive effects, induced by exercise have not been clearly established. To our knowledge, no study has examined the effect of an aerobic exercise-training program on prehypertension (resting blood pressure between 120/80 - 139/89 mm Hg) and the underlying variables that may exacerbate the disease's development in apparently healthy African American women. Therefore, the aim of the present study was to investigate the effects of a 10-week aerobic exercise-training regimen on total peripheral resistance (TPR), heart rate variability (HRV), and prehypertensive blood pressure status in apparently healthy African American women. Twenty-three prehypertensive African American women served as study participants. Each participant was required to meet all inclusionary criteria which included: being an African American woman between the ages of 30-45 years, a sedentary lifestyle, non-smoking status, body mass index between 25-35 (kg·m[superscript -2]), and a prehypertensive blood pressure status. A VO[subscript 2 peak] and submaximal exercise test were conducted on the cycle ergometer. HRV was assessed using power spectral analys is of beat-to-beat measurements in various frequency domains. Results revealed a significant reduction in TPR in the trained group from pre to post intervention periods (pre 35.3 [plus/minus] 5.1 mm Hg · L · min[superscript -1] vs. post 26.9 [plus/minus] 4.3 mm Hg · L · min [superscript -1]) (p

Book Description
Abstract: Introduction: One out of four Americans has Hypertension (HTN). Furthermore, HTN is more prevalent in African American women than any segment of the population. Research has shown that blood pressure as low as 115/75 has a positive relationship with an increase risk of cardiovascular disease and doubles the risk with every rise of 20/10 mmHg. Thus, health associations have determined a new category of blood pressure called prehypertension. Aerobic exercise training decreases blood pressure significantly. There are few studies on African American women and how exercise affects blood pressure. The exercise related variables that are of interest include cardiac output (CO), heart rate (HR), total peripheral resistance (TPR), stroke volume (SV), peak volume of oxygen consumption (VO2peak) and blood pressure. Therefore, the purpose of this study is to determine if the changes of the cardiovascular variables that may occur during a ten-week exercise training program can predict a decrease of blood pressure in prehypertensive African American women. Methods: A total of 12 sedentary women that met the inclusionary criteria were taken through three pre-training visits. These visits include orientation, pre-VO2peak test, and pre-CO2 rebreathing test. Orientations consisted of paperwork explaining confidentiality through HIPPA regulation and inform consent. The VO2peak test was performed on a cycle ergometer using a 2 minute protocol while monitoring with a standard 12-lead ECG system. The third visit consisted of a standard procedure of indirect non-invasive CO2 rebreathing test to determine CO, SV, and TPR. The CO2 rebreathing test was performed on a cycle ergometer while monitoring with the ECG system. Following testing subjects (n=12) trained for ten weeks three times a week thirty minutes a session at 70% of their VO2peak with increases of intensity every 2 1/2 weeks. Once training was completed, the subjects repeated the VO2peak test and CO2 rebreathing test to obtain post values. Results: Using the SPSS statistical analysis software and a paired sample t-test, I observed that there were not any significant changes from pre-and post-training for HR, SBP, DBP, and MAP. However, there were significant changes (p

Book Description
The book provides an intensive overview on exercise for cardiovascular disease prevention and treatment, from basic research to clinical practice. The volume firstly summarizes the acute and chronic response to exercise. Secondly, evidence for exercise as medicine for the heart based on clinical studies and basic research is summarized. Thirdly, molecular mechanisms mediating the beneficial effects of exercise including IGF-1-PI3K-AKT signalling, NO signalling, C/EBPB-Cited4 signalling, Non-coding RNAs, epigenetic regulators, mitochondria adaption and exosomes are presented. Finally, exercise dosing, prescription and future prospects are provided. This book will provide valuable reference for researchers in cell biology, physiology, as well as physician, physical therapist in cardiology, sport medicine, etc.

Book Description
Physiological responses after maximal and submaximal exercise are routinely monitored in a plethora of diseases (e.g. cardiovascular diseases, cancer, diabetes, asthma, neuromuscular disorders), and normal populations (e.g. athletes, youth, elderly), while slower or irregular post-exercise recovery usually indicates poor health and/or low fitness level. Abnormal post-exercise recovery (as assessed via blunted post-exercise heart rate dynamics) helps to predict the presence and severity of coronary artery disease, while differences in recovery outcomes in athletes might discriminate between fit and unfit individuals. Disturbances in post-exercise recovery might be due to acute or persistent changes in: (1) adaptive responses mediated by the autonomic nervous system and vasodilator substances, (2) cellular bioenergetics, and/or (3) muscular plasticity. Preliminary evidence suggests possible role of time-dependent modulation of nitric oxide synthase and adenosine receptors during post-exercise recovery, yet no molecular attributes of post-exercise recovery are revealed so far. Currently several markers of post-exercise recovery are used (e.g. heart rate measures, hormone profiles, biochemical and hematological indices); however none of them meets all criteria to make its use generally accepted as the gold standard. In addition, recent studies suggest that different pharmacological agents and dietary interventions, or manipulative actions (e.g. massage, cold-water immersion, compression garments, athletic training) administered before, during or immediately after exercise could positively affect post-exercise recovery. There is a growing interest to provide more evidence-based data concerning the effectiveness and safety of traditional and novel interventions to affect post-exercise recovery. The goals of this research topic are to critically evaluate the current advances on mechanisms and clinical implications of post-exercise recovery, and to summarize recent experimental data from interventional studies. This knowledge may help to identify the hierarchy of key mechanisms, and recognize methods to monitor and improve post-exercise recovery in both health and disease.

Book Description
Hypertension remains a leading cause of disability and death worldwide. Self-monitoring of blood pressure by patients at home is currently recommended as a valuable tool for the diagnosis and management of hypertension. Unfortunately, in clinical practice, home blood pressure monitoring is often inadequately implemented, mostly due to the use of inaccurate devices and inappropriate methodologies. Thus, the potential of the method to improve the management of hypertension and cardiovascular disease prevention has not yet been exhausted. This volume presents the available evidence on home blood pressure monitoring, discusses its strengths and limitations, and presents strategies for its optimal implementation in clinical practice. Written by distinguished international experts, it offers a complete source of information and guide for practitioners and researchers dealing with the management of hypertension.

Book Description
The main aim of this book is to evaluate the concept of stress and provide tools for physicians to identify patients who might benefit from stress management. This will incorporate a detailed description of the physiological and pathophysiological consequences of acute and chronic stress that might lead to cardiovascular disease. The book will aim to critically evaluate interventional research (behavioural and other therapies) and provide evidence based recommendations on how to manage stress in the cardiovascular patient. Our intentions are to define and highlight stress as an etiological factor for cardiovascular disease, and to describe an evidence based "tool box" that physicians may use to identify and manage patients in whom stress may be an important contributing factor for their disease and their risk of suffering cardiovascular complications.
