This book highlights circulatory dynamics and cardiovascular control during exercise and post-exercise and recovery. Composed of seven chapters, it begins with an introduction to the enhanced recovery of heart rate to its pre-exercise resting level by light exercise, compared with heart rate during complete-rest recovery. The second chapter deals with similar time courses of mean blood pressure during recovery from exercise in an upright and a supine position. The recovery of a slowly decreasing heart rate after exercise is shown in the third chapter and facilitated by cool-down exercise. Chapter four addresses that a biphasic change in heart rate at the onset of light exercise, occurs from rest in upright, but not in a supine posture. The book then highlights postexercise regulation of the cardiovascular system between inactive and active recovery from moderate cycle exercise in an upright and a supine position in the fifth chapter. Chapter six demonstrates the differences in bloodflow velocity in the femoral artery measured by Doppler ultrasound velocimetry between inactive, passive, and active recovery. The book finally presents the Doppler measurement of blood flow velocity in the middle cerebral artery at rest and during cycle exercise and compares measurements between men and women. This publication aims for a broad audience that includes medical students and residents, graduate students in the medical sciences, kinesiology, biomedical engineering, and sports medicine, specialists in aerospace medicine and gravitational physiology, cardiologists, and any physician or medical professional with an interest in human cardiovascular function.

This new analysis of reflex and hormonal control of the human cardiovascular system developed from questions raised in Human Circulation: During Physical Stress (Rowell, 1986) and from recent findings. The goal is to help students, physiologists and clinicians understand the control of pressure, vascular volume, and blood flow by examining the cardiovascular system during orthostasis and exercise, two stresses that most affect these variables. A discussion of the passive physical properties of the vascular system provides a basis for explaining how vascular control is modified by mechanical, neural, and humoral factors. Interactive effects of the vasculature on cardiac performance are emphasized; they reveal the importance of autonomic control, supplemented by muscle pumping, in maintaining adequate ventricular filling pressure. The author's detailed analysis of how total oxygen consumption is restricted focuses on limitations in cardiac pumping ability, oxygen diffusion from lungs to blood and from blood to active muscle, oxidative metabolism and neural control of organ blood flow. An unsolved mystery is the nature of the signals that govern the cardiovascular responses to exercise. This is discussed in a new and critical synthesis of ideas and evidence concerning the "error signals" that are sensed and then corrected by activation of the autonomic nervous system during exercise.

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.

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.

Every trainee in anaesthesia requires a thorough understanding of basic physiology and its application to clinical practice. Now in its second edition, this comprehensively illustrated textbook bridges the gap between medical school and reference scientific texts. It covers the physiology requirements of the Primary FRCA examination syllabus. Chapters are organised by organ system, with particular emphasis given to the respiratory, cardiovascular and nervous systems. The practical question-and-answer format helps the reader prepare for oral examinations, while 'clinical relevance' boxes translate the physiological concepts to clinical practice. This new edition has been thoroughly updated and revised throughout, and includes six new chapters, including the physiology of the eye, upper airway and exercise testing. It provides junior anaesthetists with an essential 'one stop' physiology resource.
