Cardiovascular Adaptation to Spaceflight
The Journal of Clinical Pharmacology, 1991Data are presented on the rate of adaptation of the human cardiovascular system to conditions of spaceflight, with particular attention given to data obtained during spaceflight in the U.S. Space Shuttle Program. It is pointed out that many of the cardiovascular changes that occurred during spaceflights that lasted from 2 to 11 days can be traced ...

Orthostatic intolerance after spaceflight
Journal of Applied Physiology, 1996Orthostatic intolerance occurs commonly after spaceflight, and important aspects of the underlying mechanisms remain unclear. We studied 14 individuals supine and standing before and after three space shuttle missions of 9-14 days. After spaceflight, 9 of the 14 (64%) crew members could not complete a 10-min stand test that all completed preflight ...

Cardiovascular adaptation to spaceflight
Medicine & Science in Sports & Exercise, 1996This article reviews recent flight and ground-based studies of cardiovascular adaptation to spaceflight. Prominent features of microgravity exposure include loss of gravitational pressures, relatively low venous pressures, headward fluid shifts, plasma volume loss, and postflight orthostatic intolerance and reduced exercise capacity.

Pharmacokinetic Consequences of Spaceflight
Annals of the New York Academy of Sciences, 1991Spaceflight induces a wide range of physiological and biochemical changes, including disruption of gastrointestinal (GI) function, fluid and electrolyte balance, circulatory dynamics, and organ blood flow, as well as hormonal and metabolic perturbations.

Exercise countermeasures for spaceflight
Acta Astronautica, 1995NASA: The authors present a physiological basis for the use of exercise as a weightlessness countermeasure, outline special considerations for the development of exercise countermeasures, review and evaluate exercise used during space flight, and provide new approaches and concepts for the implementation of novel exercise countermeasures for future ...

Lymphocyte reactivity during spaceflight
Immunology Today, 1985Over twenty years of spaceflight have demonstrated that man can easily survive and work in weightless conditions. However, a number of physiological changes may affect crew performance in space. Besides the well known disturbances of the vestibular and cardiovascular systems, bone demineralization, and decrease of erthrocyte mass, certain ...

Automation in manned spaceflight
Acta Astronautica, 1992With the ever increasing complexity and use of advanced technologies in the development of equipment and experiments in spaceflight, the possibility offers itself to automating repetitious or very sensitive operations. The implementation of such automation lends itself well to teleoperations and the eventual introduction of artificial intelligence ...
