Human Physiology in Extreme Environments


Book Description

Human Physiology in Extreme Environments is the one publication that offers how human biology and physiology is affected by extreme environments while highlighting technological innovations that allow us to adapt and regulate environments. Covering a broad range of extreme environments, including high altitude, underwater, tropical climates, and desert and arctic climates as well as space travel, this book will include case studies for practical application. Graduate students, medical students and researchers will find Human Physiology in Extreme Environments an interesting, informative and useful resource for human physiology, environmental physiology and medical studies. - Presents human physiological challenges in Extreme Environments combined in one single resource - Provides an excellent source of information regarding paleontological and anthropological aspects - Offers practical medical and scientific use of current concepts




An Overview of Gravitational Physiology


Book Description

The focus of this review is on the response of humans and animals to the effects of the near weightless condition occurring aboard orbiting spacecraft. Gravity is an omnipresent force that has been a constant part of our lives and of the evolution of all living species. Emphasis is placed on the general mechanisms of adaptation to altered gravitational fields and vectors, i.e., both hypo- and hypergravity. A broad literature review of gravitational biology was conducted and the general state of our knowledge in this area is discussed. The review is specifically targeted at newcomers to the exciting and relatively new area of space and gravitational biology. Miquel, Jaime and Souza, Kenneth A. Ames Research Center...




Gravitational Physiology


Book Description

Advances in Physiological Sciences, Volume 19: Gravitational Physiology covers the proceedings of the 28th International Congress of Physiological Sciences. The volume presents studies that tackle the biological concerns caused by the interactions between complex living organisms and altered gravitational field. The articles in the text are organized into parts, based on their main theme. The first part presents materials about the general problems when adapting to altered gravity system, such as physiological mechanisms of adaptation of mammals to weightlessness, and studies of biorhythms in biosatellite experiments. In the next part, the selection presents papers about metabolism and morphology that include stress metabolic aspects in space flight and the effect of spaceflight on human lymphocyte activation. The text also covers the function and structure of gravity-dependent systems, along with hypokinesia and immobilization. The book will be of great interest to health professionals involved in various space programs.
















High G Flight


Book Description

This book provides a unique, authoritative and detailed examination of the physiological and clinical consequences of human exposure to high G forces. Pilots of military fast jets, civilian aerobatic pilots and astronauts during the launch and re-entry phases of spaceflight are frequently and repetitively exposed to high G forces, for which the human body is not fundamentally designed. The book examines not only the nature of the high G environment, but the physiological effects of exposure to high G on the various systems of the human body. In particular, the susceptibility of the human cardiovascular system to high G is considered in detail, since G-Induced Loss of Consciousness (G-LOC) is a serious hazard for high G pilots. Additionally, the factors that influence tolerance to G and the emerging scientific evidence of physiological adaptation to high G are examined, as are the various countermeasures and techniques that have been developed over the years to protect pilots from the potentially adverse consequences of high G flight, such as the G-suit and positive pressure breathing. The accumulated knowledge of human exposure to high G is drawn together within High G Flight, resulting in a definitive volume on the physiological effects of high G and their countermeasures.
