This book was released on 2020-03-04 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human spaceflight has required space agencies to study and develop exercise countermeasure (CM) strategies to manage the profound, multi-system adaptation of the human body to prolonged microgravity (μG). Future space exploration will present new challenges in terms of adaptation management that will require the attention of both exercise physiologists and operational experts. In the short to medium-term, all exploration missions will be realised using relatively small vehicles/habitats, with some exploration scenarios including surface operations in low (<1G) gravity conditions. The evolution of CM hardware has allowed modern-day astronauts to return to Earth with, on average, relatively moderate levels μG-induced adaptation of the musculoskeletal (MS) and cardiovascular (CV) systems. However, although the intense use of CM has attenuated many aspects of MS and CV adaptation, on an individual level, there remains wide variation in the magnitude of these changes. Innovations in CM programs have been largely engineering-driven, with new hardware providing capability for new modes of exercise and a wider range of exercise protocols, which, in turn, has facilitated the transfer of traditional, but effective, terrestrial concepts based around high frequency resistance (multiple-set, multiple repetition) and mediumintensity continuous aerobic training. As a result, International Space Station (ISS) CM specialists have focused their efforts in these domains, taking advantage of hardware innovations as and when they became available. However, terrestrial knowledge in human and exercise physiology has expanded rapidly during the lifetime of the ISS and, consequently, there is potential to optimize current approaches by re-examining terrestrial knowledge and identifying opportunities to implement this knowledge into operational practices. Current terrestrial knowledge in exercise physiology is the product of a large number of intervention studies in which the variables that contribute to the effects of physical activity (mode, frequency, duration, intensity, recovery) have been controlled and systematically manipulated. However, due to limited opportunities to perform intervention studies in both spaceflight analogues – head-down bed rest (HDBR) being considered the ‘gold standard’ – and spaceflight itself, it will not be possible to systematically investigate the contribution of these factors to the efficacy of in-flight CM. As such, it will be necessary to draw on terrestrial evidence to identify solutions/strategies that may be best suited to the constraints of exploration and prioritise specific solutions/strategies for evaluation in HDBR and in flight.

Download or read book Space Countermeasures and Medicine Implementation into Earth medicine and Rehabilitation written by Elena S. Tomilovskaya and published by Frontiers Media SA. This book was released on 2023-09-08 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of microgravity on the human organism have been studied for over 60 years. The experience of short- and long-term space flights revealed alterations in multiple physiological systems either in the course of the flight or afterward. Some of these changes represent serious risks for crew health and functional capacity. This fact served as the trigger for multiple countries with space program participants to develop spaceflight countermeasures and medical support systems. These activities are intended to counteract space flight effects such as axial and support unloading, muscle disuse, monotony, fluid redistribution, sensory deficit, etc. Some countermeasures have been adapted from Earth medicine and sports, while others have been created especially for space flights. Many of the observed space flight effects have similarities to conditions seen on Earth, such as: decrease of motor activity in aging people, immobilized patients, and professions associated with forced physical inactivity and isolation. Thus, many space countermeasures and medical support systems can be applied in Earth medicine and rehabilitation. For example, countermeasures like loading suits, lower body negative pressure suits, electromyostimulation of various regimens, water-salt supplements, vestibular training means, etc. have been used in Earth medicine and sports conditioning over the last 20 years.

Download or read book The Human Body and Weightlessness written by William Thornton and published by Springer. This book was released on 2017-10-11 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on all of the major problems associated with the absence of body weight in space, by analyzing effects, adaption, and re-adaptation upon returning to Earth, using sound scientific principles embedded in a historical context. Serious problems for space travelers range from Space Motion Sickness (SMS) to recently discovered ocular effects that may permanently impair vision. Fluid loss and shifts, spinal changes, and bone and muscle loss are also all results of weightlessness. Starting with a brief definition and history of weightlessness, the authors then address in detail each problem as well as the countermeasures aimed at alleviating them. In some cases, alternative hypotheses regarding what can and should be attempted are also presented. As plans for long-term missions to the Moon and Mars develop, it will be essential to find countermeasures to weightlessness that are effective for missions that could span years.
Download or read book Workshop on Exercise Prescription for Long Duration Space Flight written by Bernard A. Harris (Jr.) and published by . This book was released on 1989 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Aeronautics and Space Administration has a dedicated history of ensuring human safety and productivity in flight. Working and living in space long term represents the challenge of the future. Our concerns are no longer getting a man into space but in determining the effects on the human body of living in space. Space flight provides a powerful stimulus for adaptation, such as cardiovascular and musculoskeletal deconditioning. Extended-duration space flight will influence a great many systems in the human body. We must understand the process by which this adaptation occurs. The NASA is agressively involved in developing programs which will act as a foundation for this new field of "space medicine." The hallmark of these programs deals with prevention of deconditioning, currently referred to as "countermeasures to zero g." Exercise appears to be most effective in preventing the cardiovascular and musculoskeletal degradation of microgravity. This document is a culmination of discussions from an exercise workshop held at the NASA Johnson Space Center. The proceedings from this session provide a comprehensive review of the physiology of exercise and recommendations on the use of exercise as a countermeasure for adaptation to a microgravity environment.

Download or read book Preparation Implementation and Execution of Human Cardiovascular Experiments in Space written by Peter Norsk and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are eight steps in the preparation, implementation and execution of a human spaceflight experiment: (1) writing a proposal, (2) being selected by a space agency, (3) finding funding, (4) flight feasibility assessment for flight, (5)¬†implementation into a specific space platform (e.g. the Space Shuttle in the past and now the International Space Station), (6) experiment execution, (7) analysis of collected data and (8) publication. The unique features about spaceflight experiments are steps 4,Äì6 because of the limitations of conducting experimental procedures in space. Furthermore, all of the associated equipment have to be developed and approved for spaceflight with all the safety aspects taken appropriately into consideration. In this chapter, two specific experiments from the Spacelab D2 mission in 1993 are used as illustration of these steps as well as describing the use of parabolic flights as a preparatory platform. It is important to have data collected of such a quality that they can be published in science journals with external peer review. It is also important that the data not only have operational spaceflight applications but also can advance knowledge for terrestrial science purposes.
Download or read book Recapturing a Future for Space Exploration written by National Research Council and published by National Academies Press. This book was released on 2012-01-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.

This book was released on 2014-12-15 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human Adaptation to Spaceflight: The Role of Nutrition reflects a (brief) review of the history of and current state of knowledge about the role of nutrition in human space flight. We have attempted to morganize this from a more physiological point of view, and to highlight systems, and the nutrients that support them, rather than the other way around. We hope we have captured in this book the state of the field of study of the role of human nutrition in space flight, along with the work leading up to this state, and some guideposts for work remaining to be done and gaps that need to be filled.

Download or read book Nutritional Biochemistry of Space Flight written by Scott M. Smith and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Besides covering a broad range of issues relating to space nutrition, this book presents the knowledge of nutritional biochemistry of space flight that has resulted from five decades of space life sciences research and operations. It covers research and observational findings on space travellers, as well as ground-based analogue studies with human subjects in such venues as bed rest, closed chambers, Antarctica, and under the sea. This book serves as a historical record of nutrition as related to space flight, specifically to nutrient requirements in a space flight environment. Evidence is reviewed from the first days of human space flight through what may very well be the early days of permanent off-Earth human presence. This information has been scattered in research articles and limited reviews that have been published over the years, in some cases documented only in out-of-publication NASA documents. The book will be of interest to scientists and physicians in many disciplines, including nutrition, physiology, biochemistry, space life sciences, and aerospace medicine. The text is aimed at an upper-undergraduate or graduate-student level of understanding.
