Exercise countermeasures for spaceflight

Acta Astronautica, 1995
NASA: 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 ...

Spaceflight Environment

Emergency Medicine Clinics of North America
The safety and health of individuals who may be exposed to the spaceflight environment are first and foremost cared for through prevention. This environment, which encompasses microgravity, radiation, and alternobaric factors, can have physiologic impacts on every human system.

Circulating miRNA Spaceflight Signature Reveals Targets for Countermeasure Development

Cell Reports, 2020
We have identified and validated a spaceflight-associated microRNA (miRNA) signature that is shared by rodents and humans in response to simulated, short-duration and long-duration spaceflight. Previous studies have identified miRNAs that regulate rodent

Cardiovascular Adaptation to Spaceflight

The Journal of Clinical Pharmacology, 1991
Data 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 ...

Sensory-Based Alterations and Countermeasures in Spaceflight and Spaceflight Analogs

Aerospace Medicine and Human Performance
INTRODUCTION: Long-duration spaceflight and isolated, confined, and extreme environments present various challenges to crewmembers. One less-frequently discussed challenge is altered sensory inputs and how they can adversely affect cognition and performance.

Nutrition and Metabolism in Spaceflight

The Journal of Nutrition, 1987
The United States Space Station being planned for the 1990s will accommodate six or more crew members on 90-d flights in low earth orbit. Adequate nutrition will be essential for maintaining crew health, effectiveness and morale. Although much is known from prior space experience about in-flight metabolism, nutrition and associated food technology ...

Pharmacodynamic Aspects of Spaceflight

The Journal of Clinical Pharmacology, 1991
Little is known at present about the effects of human exposure to microgravity on the pharmacodynamics of medicinal agents. Considering the known physiologic perturbations associated with spaceflight and the effects of some of these perturbations on the pharmacodynamics of certain medicinals that act on the central nervous system, it is likely that the

Cardiovascular adaptation to spaceflight

Medicine &amp Science in Sports &amp Exercise, 1996
This 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, 1991
Spaceflight 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.
