Download or read book Physiological Responses to Prolonged Bed Rest and Fluid Immersion in Man written by John Edward Greenleaf and published by . This book was released on 1982 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water immersion and prolonged bed rest reproduce nearly all the physiological responses observed in astronauts in the weightless state. Moreover, it appears that relative to actual weightlessness, given responses tend to occur sooner in immersion and later in bed rest. Much research has been conducted on humans using these two techniques, especially by Russian scientists. This compendium contains abstracts and annotations of reports that appeared in the literature from January 1974 through December 1980. Two other related compendia have been published: Adaptation to Prolonged Bed Rest in Man: A Compendium of Research, by J.E. Greenleaf, C.J. Greenleaf, D. Van Derveer, and K.J. Dorchak (NASA TM X-3307, 1976); and Physiologic Responses to Water Immersion in Man: A Compendium of Research, by J. Kollias, D. Van Derveer, K.J. Dorchak, and J.E. Greenleaf (NASA TM X-3308, 1976).

Available in PDF, EPUB and Kindle. Book excerpt: The purpose for this 30-day bed-rest study was to investigate the effects of short-term, high-intensity isotonic and isokinetic exercise training on maintenance of aerobic work capacity (peak oxygen uptake); muscular strength and endurance; and orthostatic tolerance, equilibrium, and gait. Other data were collected on muscle atrophy, bone mineralization and density, endocrine analyses of vasoactivity and fluid-electrolyte balance, muscle intermediary metabolism, and performance and mood of the subjects. Nineteen men (32-42 yr) were allocated into three groups: no-exercise control (peak oxygen uptake and isokinetic tests once/wk, N = 5), isotonic exercise training (electronic Quinton ergometer, supine, N = 7), and isokinetic exercise training (electronic Lido ergometer, supine, N = 7). The exercise training regimens were conducted near peak levels for 30 min in the morning and 30 min in the afternoon 5 d/wk. The protocol consisted of a 7-d ambulatory control period during which the subjects equilibrated on the standardized diet, 30 d of 6 degrees head-down bed rest, and a final 4.5 d of ambulatory recovery. Their diet consisted of commonly available fresh and frozen foods; mean caloric consumption of 2,678 +/- SE 75 kcal/d (control), 2,833 +/- SE 82 kcal/day (isotonic), and 2,890 +/- SE 75 kcal/d (isokinetic) resulted in mean weight losses during bed rest of 1.01 kg, 0.85 kg, and 0.0 kg, respectively. The results indicated that: (1) The subjects maintained a relatively stable mood, high morale, and high esprit de corps throughout the study. Scores improved in nearly all performance and mood tests in almost all the subjects. Isotonic training, as opposed to isokinetic exercise training, was associated with decreasing levels of psychological tension, concentration, and motivation, and with improvement in the quality of sleep. (2) Peak oxygen uptake was maintained during bed rest with isotonic exercise training; it was not maintained as well with isokinetic ( -9.0%) or no-exercise ( -18.2%) training. If a 9% reduction in aerobic power is acceptable, isokinetic exercise training could be used for maintenance of strength, endurance, and the reduced aerobic capacity in astronauts during flight. (3) In general, there were few decreases in strength or endurance of arm or leg muscles during bed rest, in spite of reduction in size (atrophy) of some leg muscles. (4) There was no effect of isotonic or isokinetic exercise training on orthostasis, because tilt-table tolerances were reduced similarly from 42-53 min to 30-34 min in the three groups following bed rest. (5) Bed rest resulted in significant decreases of postural stability and self-selected step length, stride length, and walking velocity, which were not influenced by either exercise training regimen. Pre-bed-rest responses were restored by the fourth day of recovery.

Download or read book Fragility Fracture Nursing written by Karen Hertz and published by Springer. This book was released on 2018-06-15 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book aims to provide a comprehensive but practical overview of the knowledge required for the assessment and management of the older adult with or at risk of fragility fracture. It considers this from the perspectives of all of the settings in which this group of patients receive nursing care. Globally, a fragility fracture is estimated to occur every 3 seconds. This amounts to 25 000 fractures per day or 9 million per year. The financial costs are reported to be: 32 billion EUR per year in Europe and 20 billon USD in the United States. As the population of China ages, the cost of hip fracture care there is likely to reach 1.25 billion USD by 2020 and 265 billion by 2050 (International Osteoporosis Foundation 2016). Consequently, the need for nursing for patients with fragility fracture across the world is immense. Fragility fracture is one of the foremost challenges for health care providers, and the impact of each one of those expected 9 million hip fractures is significant pain, disability, reduced quality of life, loss of independence and decreased life expectancy. There is a need for coordinated, multi-disciplinary models of care for secondary fracture prevention based on the increasing evidence that such models make a difference. There is also a need to promote and facilitate high quality, evidence-based effective care to those who suffer a fragility fracture with a focus on the best outcomes for recovery, rehabilitation and secondary prevention of further fracture. The care community has to understand better the experience of fragility fracture from the perspective of the patient so that direct improvements in care can be based on the perspectives of the users. This book supports these needs by providing a comprehensive approach to nursing practice in fragility fracture care.

Download or read book Musculoskeletal Disorders and the Workplace written by Institute of Medicine and published by National Academies Press. This book was released on 2001-05-24 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year workers' low-back, hand, and arm problems lead to time away from jobs and reduce the nation's economic productivity. The connection of these problems to workplace activities-from carrying boxes to lifting patients to pounding computer keyboards-is the subject of major disagreements among workers, employers, advocacy groups, and researchers. Musculoskeletal Disorders and the Workplace examines the scientific basis for connecting musculoskeletal disorders with the workplace, considering people, job tasks, and work environments. A multidisciplinary panel draws conclusions about the likelihood of causal links and the effectiveness of various intervention strategies. The panel also offers recommendations for what actions can be considered on the basis of current information and for closing information gaps. This book presents the latest information on the prevalence, incidence, and costs of musculoskeletal disorders and identifies factors that influence injury reporting. It reviews the broad scope of evidence: epidemiological studies of physical and psychosocial variables, basic biology, biomechanics, and physical and behavioral responses to stress. Given the magnitude of the problem-approximately 1 million people miss some work each year-and the current trends in workplace practices, this volume will be a must for advocates for workplace health, policy makers, employers, employees, medical professionals, engineers, lawyers, and labor officials.

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 Homelessness Health and Human Needs written by Institute of Medicine and published by National Academies Press. This book was released on 1988-02-01 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have always been homeless people in the United States, but their plight has only recently stirred widespread public reaction and concern. Part of this new recognition stems from the problem's prevalence: the number of homeless individuals, while hard to pin down exactly, is rising. In light of this, Congress asked the Institute of Medicine to find out whether existing health care programs were ignoring the homeless or delivering care to them inefficiently. This book is the report prepared by a committee of experts who examined these problems through visits to city slums and impoverished rural areas, and through an analysis of papers written by leading scholars in the field.

Download or read book Clinical Exercise Testing written by Idelle M. Weisman and published by Karger Medical and Scientific Publishers. This book was released on 2002-01-01 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last several years, Clinical Exercise Testing has become an increasingly important tool for patient evaluation in clinical medicine due to a growing awareness of the limitations of traditional resting cardiopulmonary measurements. Emphasizing scientific and technological advances and focusing on clinical applications for patient diagnosis and management, this volume provides a comprehensive interdisciplinary review of clinical exercise testing, concentrating on Cardiopulmonary Exercise Testing (CPET). 25 reader-friendly chapters discuss important topics, including the physiologic responses to exercise in normal subjects, in the aged and in various disease states; the set-up of an exercise lab; the methodology and protocols used for clinical exercise testing; and an integrative approach to the interpretation of CPET results. CPET in heart failure, deconditioning, COPD, ILD, pulmonary vascular disease, neuromuscular disease, and asthma is thoroughly discussed. Clinical applications including pulmonary and cardiac rehabilitation, heart and lung transplantation evaluation, unexplained exertional dyspnea assessment, evaluation for lung resection and lung volume reduction surgery, and impairment-disability evaluation are also covered in detail. Additional chapters on clinical exercise testing in children, during pregnancy and the postpartum, and in other systemic disorders complete this extensive publication. Written by well-respected experts, this volume will be a valuable resource for a wide audience including pulmonologists, cardiologists, pediatricians, exercise physiologists, rehabilitation specialists, nurse clinician specialists, and respiratory therapists.
