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.

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.

It is well known that acute, severe hyponatremia is a life-threatening situation. However, there is growing evidence that mild and chronic hyponatremia may also have negative consequences. Gait disturbances, attention deficits, falls and fractures, and bone loss have all been reported, with increased mortality in almost every disease state if the patient is hyponatremic. This book has been written by key opinion leaders in the field and covers a spectrum of crucial aspects of hyponatremia, including a historical perspective, physiology and pathophysiology of water homeostasis, epidemiology of hyponatremia, and clinical features. A detailed description of all available therapies has been incorporated, with a guide to a clinician's approach to key therapeutic situations. Hyponatremia is a topic that encompasses all areas of medicine, so this book will be of interest to specialists such as endocrinologists, nephrologists and internists, but will also be a valuable resource for all clinicians who manage patients with hyponatremia.

This book reviews the research pertaining to nutrient requirements for working in cold or in high-altitude environments and states recommendations regarding the application of this information to military operational rations. It addresses whether, aside from increased energy demands, cold or high-altitude environments elicit an increased demand or requirement for specific nutrients, and whether performance in cold or high-altitude environments can be enhanced by the provision of increased amounts of specific nutrients.

Now in its fully revised and expanded third edition, this comprehensive text represents a compilation of the critical endocrinology topics in the areas of sports medicine, kinesiology and exercise science, written by leading experts in the field. As in previous editions, the focus here is on the critical issues involved in understanding human endocrinology and hormonal workings with regards to physical activity, exercise and sport and how such workings impact the full range of medical conditions, overall health and physiological adaptation. Chapters included discuss the effect of exercise on the HPA axis, the GH-IGF-1 axis, thyroid function, diabetes, and the male and female reproductive systems, among other topics. Additional chapters present the current evidence on circadian endocrine physiology, exercise in older adults, exercise and hormone regulation in weight control, and the effects of overtraining in sports. Chapters brand new to this edition present the role of hormones in muscle hypertrophy, the effect of exercise on hormones in metabolic syndrome patients, how exercise impacts appetite-regulating hormones in clinical populations, and the relative energy deficiency in sport (RED-S) condition.

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.

Exercise training provokes widespread transformations in the human body, requiring coordinated changes in muscle composition, blood flow, neuronal and hormonal signaling, and metabolism. These changes enhance physical performance, improve mental health, and delay the onset of aging and disease. Understanding the molecular basis of these changes is therefore important for optimizing athletic ability and for developing drugs that elicit therapeutic effects. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine examines the biological basis of exercise from the molecular to the systemic levels. Contributors discuss how transcriptional regulation, cytokine and hormonal signaling, glucose metabolism, epigenetic modifications, microRNA profiles, and mitochondrial and ribosomal functions are altered in response to exercise training, leading to improved skeletal muscle, hippocampal, and cardiovascular function. Cross talk among the pathways underlying tissue-specific and systemic responses to exercise is also considered. The authors also discuss how the understanding of such molecular mechanisms may lead to the development of drugs that mitigate aging and disease. This volume will therefore serve as a vital reference for all involved in the fields of sports science and medicine, as well as anyone seeking to understand the molecular mechanisms by which exercise promotes whole-body health.
