Man At High Altitude

Leading authorities on high-altitude physiology contribute to this work, which is divided into three sections: Man at Extreme Altitude; Sleep and Restoration at High Altitude; and Physiology of Permanent Residents of High Altitude. Based on a symposium on physiology at high altitude sponsored by the American Physiological Society, the volume includes several chapters on the achievements of the 1981 American Medical Research Expedition to Mt. Everest, where the first physiological measurements at altitudes above 8,000 meters were recorded. With growing interest in the study of human performance in these conditions, this text marks a lasting achievement in high-altitude physiology.

The Physiological Effects of High Altitude covers the concepts and principles in high altitude physiology. This book is divided into four main sections that discuss the adaptive mechanisms in natural acclimatization and the bodily processes of exercise at high altitudes. Some of the topics covered in the book are the development of chronic mountain sickness; comparison of growth and development of the rat at high altitude; body weight during early acclimatization; experiments on wound healing and activity of the adrenocortical system; and experiments on pregnancy and lactation. Other sections deal with the volume and structure of erythrocytes and hemoglobin at high altitude, particularly the responses of deer mice to altitude. This book also examines the hematologic changes during rest and physical activity in man at high altitude. The remaining sections are devoted to the hematologic changes during physical activity, as well as the hypoxic stimulus and mechanism of erythropoiesis. The book can provide useful information to doctors, students, and researchers.

This pre-eminent work has developed over six editions in response to man's attempts to climb higher and higher unaided, and to spend more time at altitude for both work and recreation. Building on this established reputation, the new and highly experienced authors provide a fully revised and updated text that will help doctors continue to improve the health and safety of all people who visit, live or work in the cold, thin air of high mountains. The sixth edition remains invaluable for any doctor accompanying an expedition or advising patients on a visit to altitude, those specialising in illness and accidents in high places, and for physicians and physiologists who study our dependence on oxygen and the adaptation of the body to altitude.

The activities of the Food and Nutrition Board's Committee on Military Nutrition Research (CMNR, the committee) have been supported since 1994 by grant DAMD17-94-J-4046 from the U.S. Army Medical Research and Materiel Command (USAMRMC). This report fulfills the final reporting requirement of the grant, and presents a summary of activities for the grant period from December 1, 1994 through May 31, 1999. During this grant period, the CMNR has met from three to six times each year in response to issues that are brought to the committee through the Military Nutrition and Biochemistry Division of the U.S. Army Research Institute of Environmental Medicine at Natick, Massachusetts, and the Military Operational Medicine Program of USAMRMC at Fort Detrick, Maryland. The CMNR has submitted five workshop reports (plus two preliminary reports), including one that is a joint project with the Subcommittee on Body Composition, Nutrition, and Health of Military Women; three letter reports, and one brief report, all with recommendations, to the Commander, U.S. Army Medical Research and Materiel Command, since September 1995 and has a brief report currently in preparation. These reports are summarized in the following activity report with synopses of additional topics for which reports were deferred pending completion of military research in progress. This activity report includes as appendixes the conclusions and recommendations from the nine reports and has been prepared in a fashion to allow rapid access to committee recommendations on the topics covered over the time period.

* Cutting-edge information on how to prevent, diagnose, and treat altitude illness and hypoxia in everyday life * Interweaves fascinating research discoveries with dramatic first-person accounts * Authored by a celebrated mountaineer and physician who pioneered research in the field From the time of his historic expedition to Nanda Devi in the high Himalaya, Charles Houston, M.D., was fascinated by the effects of altitude on the human body. Why do people get sick in the mountains? What are the symptoms of hypoxia -- lack of sufficient oxygen -- that also occurs in everyday life, sometimes chronically due to disease? How can we decrease the incidence of illness and death? This edition incorporates current research on the effects of altitude on humans, and Houston (now deceased) joined forces with an educator and a medical writer in a text made even more accessible for the average reader while retaining the depth of material of particular use to the medical community. This edition of this seminal text added chapters on vision and the eye at altitude, chronic and subacute altitude illness, and the limits to work at altitude (with implications for athletic training). It presents information on genetics and gender differences and more on flight and space travel, on understanding and treating sea-level hypoxic illnesses, and on who can (or should not) go to high altitude, and much more. With an expanded glossary of terms.

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.

A comprehensive update to this preeminent and accessible text, this fifth edition of a bestseller was developed as a response to man's attempts to climb unaided to higher altitudes and to spend more time in these conditions for both work and recreation. It describes the ever-expanding challenges that doctors face in dealing with the changes in huma
