Despite its crucial importance, scientists interested in the limitations of human physical performance have only just started to give the field of oxygen uptake kinetics the attention it deserves. Understanding the principal determinant of the oxygen uptake kinetics is fundamental to improving human performance or the quality of life. This book provides a detailed overview of the current state of knowledge of this emerging field of study, and features: * an introduction to oxygen uptake kinetics and historical development of the discipline * measurement and analysis of oxygen uptake kinetics * control of and limitations to oxygen uptake kinetics * applications of oxygen uptake kinetics in a range of human populations. Oxygen Uptake Kinetics in Sport, Health and Medicine is richly illustrated and structured to enable easy access of information and represents an invaluable resource for students and researchers in exercise physiology, as well as for respiratory physiologists and pulmonary clinicians.

"In this fifth edition of Principles of Exercise Testing and Interpretation, as in earlier editions, we attempt to develop conceptual advances in the physiology and pathophysiology of exercise, particularly as related to the practice of medicine. The underlying theme of the book continues to be the recognition that the most important requirement for exercise performance is transport of oxygen to support the bioenergetic processes in the muscle cells (including, of course, the heart) and elimination of the carbon dioxide formed as a byproduct of exercise metabolism. Thus, appropriate cardiovascular and ven- tilatory responses are required to match those of muscle respiration in meeting the energy demands of exercise. As depicted by the logo on the book cover, normal exercise performance requires an efficient coupling of external to internal (cellular) respiration. Appropriate treatment of exercise intolerance requires that patients' symptoms be thought of in terms of a gas exchange defect between the cell and the environment. The defect may be in the lungs, heart, peripheral or pulmonary circulations, the muscles themselves, or there may be a combination of defects. Thus, we describe the pathophysiology in gas transport and exchange that affect any site in the cardio- respiratory coupling between the lungs and the muscles. We illustrate how cardiopulmonary exercise testing can provide the means for a critical evaluation by the clinician-scientist of the functional competency of each component in the coupling of cellular to external respiration, including the cardiovascular system. To achieve this, clinical cases are used to illustrate the wide spectrum of pathophysiology capable of causing exercise intolerance"--Provided by publisher.

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.

Present-day respiratory physiology stems largely from the explosion of ideas which took place during and after World War II. A number of the major players are still active, but the opportunity to prepare a personal history of this branch of medicine will soon be lost. In a sense then, this book offers an exceptional, even unique, opportunity. We are offered a first-hand chronicle of the advancements made in respiratory physiology in the course of this century by one of the principal figures in the field. The volume covers every aspect of the evolution of this important area of knowledge: morphology, gas exchange and blood flow, mechanics, control of ventillation, and comparative physiology. Some of the chapters are personal accounts of the development of respiratory physiology as observed by the author. It is hoped that what is lost in objectivity by this approach is more than made up by the captivating insights provided by the author into the process of scientific research and discovery.

This book discusses the maximal power and capacity of the three major biochemical pathways - aerobic (oxygen consumption), anaerobic lactic (muscle lactate accumulation in absence of oxygen consumption), and anaerobic alactic (phosphocreatine hydrolysis) metabolism - as well as the factors that limit them. It also discusses the metabolic and cardio-pulmonary mechanisms of the dynamic response to exercise. The way and extent to which the power and capacity of the three major energy metabolisms are affected under a number of different conditions, such as training, hypoxia and microgravity, are also described.

The lung receives the entire cardiac output from the right heart and must load oxygen onto and unload carbon dioxide from perfusing blood in the correct amounts to meet the metabolic needs of the body. It does so through the process of passive diffusion. Effective diffusion is accomplished by intricate parallel structures of airways and blood vessels designed to bring ventilation and perfusion together in an appropriate ratio in the same place and at the same time. Gas exchange is determined by the ventilation-perfusion ratio in each of the gas exchange units of the lung. In the normal lung ventilation and perfusion are well matched, and the ventilation-perfusion ratio is remarkably uniform among lung units, such that the partial pressure of oxygen in the blood leaving the pulmonary capillaries is less than 10 Torr lower than that in the alveolar space. In disease, the disruption to ventilation-perfusion matching and to diffusional transport may result in inefficient gas exchange and arterial hypoxemia. This volume covers the basics of pulmonary gas exchange, providing a central understanding of the processes involved, the interactions between the components upon which gas exchange depends, and basic equations of the process.

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.

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.
