Book Description
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

Book Description
Cardiac problems in athletic individuals are rare, but when they occur can be devastating. This book provides a definitive review of current practice and thinking surrounding the often difficult and life-changing practice of sports cardiology. Topics which remain a challenge for practitioners, athletes and families are investigated, including cardiovascular screening, exercise participation prescription, and prevention strategies for sudden cardiac arrest. Also given are guidelines for diagnosis, management and prevention of specific cardiac illnesses.This second edition includes new information on a number of key issues surrounding modern sports and cardiology, including the athlete at altitude, heat stress in athletes, exercise aspects of swimming and diving and ergogenics in the cardiac care of athletes. Additionally, further details are given on new research related to sports and exercise for individuals with implantable cardioverter defibrillators, advanced echocardiography in athletes and non-compaction cardiomyopathy.Building on the first edition, Exercise and Sports Cardiology (2nd Edition) provides cardiologists, physicians, coaches, trainers and medical students and researchers with a comprehensive go-to reference for modern day concerns in the expanding field of sports cardiology research and treatment.

Book Description
The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

Book Description
The third edition of this popular and successful text has been fully revised and updated to take account of recent advances in the field, particularly in the physiology and pathophysiology of many disease processes. The text retains the original format of relevant physiology, test selection and test interpretation by case example. Essential aspects of paediatric chemical pathology, inborn errors of metabolism, reproductive endocrinology, tumours and toxicology are now included. As chemical pathology is receiving specific attention in medical courses, this text has been adapted to present this information in an understandable form, making it suitable for medical undergraduates and for medical and science postgraduates studying for exams of Colleges of Pathology and professional associations."

Book Description
In the network of cardiologists within the European Society of Cardiology Working Group on Cardiac Rehabilitation and Exercise Physiology there is a strong view that the time indeed is right to publish definitively on the methods involved in cardiovascular prevention and rehabilitation. We are facing a transition from conventional cardiac rehabilitation to a phase of combined preventive and rehabilitative efforts, as witnessed in the recent Joint Task Force Guidelines on Preventive Cardiology. For this revision of our clinical routines we lack a practical textbook, based upon the conditions and resources of European health care. This textbook is designed to fill that gap.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
