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 Nutrition in Spaceflight and Weightlessness Models written by Helen W. Lane and published by CRC Press. This book was released on 1999-12-20 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tens of thousands of miles above Earth's atmosphere, orbiting this planet like pieces from a child's giant erector set, NASA's massive International Space Station slowly takes shape. When completed, as many as 16 countries will provide crew members for this orbiting international community. But while this will not be the first extended stay of humans in space-Skylab, Mir Space Station, and Shuttle-Mir missions all involved extended-stay periods-it will give birth to some new questions about one of space exploration's biggest concerns: providing adequate nutrition essential to good physical and mental health in space. Nutrition in Spaceflight and Weightlessness Models consolidates nutritional observations from 38 years of human spaceflight. It is a compilation of nutritional knowledge and accomplishments from the early 1970's to the recent Shuttle-MIR program. It provides basic nutritional concepts, as well as broad coverage, of the effect of space and weightlessness on nutrition status and physiology. Nutrition in Spaceflight and Weightlessness Models addresses the utility of ground-based weightlessness simulations; the role of electrolytes, calcium, protein, iron, and micronutrients in optimal nutrition; and energy utilization by space crews. The book also explores regenerative life-support and food systems for space and planetary missions; the results of basic research in metabolism that illustrate the physiological changes that occur during spaceflight; new concepts and recommendations for astronaut nutrition in future spaceflights; and, the lab capabilities of the International Space Station.
Download or read book Inactivity Physiological Effects written by Harold Sandler and published by Elsevier. This book was released on 2012-12-02 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inactivity: Physiological Effects describes the physiological deconditioning inherent in inactivity and immobilization. This book is organized into eight chapters that review the body of information from studies on healthy volunteers conducted in direct support of the space program. Considerable chapters are devoted to the changes occurring in the cardiovascular system, bone and muscle, metabolism and endocrine responses, psychosocial responses, and exercise tolerance. Other chapters discuss the clinical effects and clinical management of deterioration while indicating the changes that have been found in health, normal bed rested subjects. The remaining chapters explore the data on crews that have flown in since their physiological responses are qualitatively similar to those observed in bed rested subjects or immobilized patients on earth. Clinicians, nursing staff, physiologists, researchers, and students in the field will find this book invaluable.
Download or read book Hormonal Regulation of Fluid and Electrolytes written by John R. Claybaugh and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of this book has developed over the past fi fteen years as interest in the water and electrolyte disturbances associated with most environmental settings moved from a research area of descriptive discovery to one dealing with the mechanisms responsible for the previously observed disturbances. Most of the contributing authors have been involved in both aspects of this evolution of research, focusing on those problems associated with body fluid and electrolyte balance and searching for hormonal explanations. What did not accompany this transition, however, was a source of information encompassing the area of interest. Instead, the previous format of environmentally focused symposia, reviews, and books continued to be the only sources available. For instance, various books deal with the physiology of high altitude, space, or exercise but do not necessarily provide adequate coverage of water and electrolyte disturbances. To our knowledge, the format of this book is unique. We have made the central focus water and electrolyte physiology with an emphasis on endocrinology and tried to comprehensively cover this area of physiology in some of the more heavily studied environments. This book too, then, will have its limitations in coverage. For instance, in-depth coverage of the respiratory and cardiovascular responses to the high altitude en vironment will not be found, but since these areas are so integrally associated with water and electrolyte regulation they are not ignored.
Download or read book Temporal Variations of the Cardiovascular System written by Thomas F.H. Schmidt and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although it is widely recognized that there are significant variations in the circulation throughout the 24-hour day, these patterns have often been conceived as nuisance variables rather than functional differences. Responses of the circulation are examined here not as stable phenomena, but as integrated functions highly sensitive to environmental conditions, and driven by internal and external pacesetters. In this volume, cardiologists with a primary interest in hypertension or heart disease, chronobiologists, and psychologists join together for the first time to give the reader the opportunity to learn the extent and clinical significance of these changes from a chronobiological, behavioral and physiological perspective.
Download or read book Biological and Medical Research in Space written by David Moore and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life Science studies in space were initially driven by the need to explore how man could survive spaceflight conditions; the effects of being launched un der high accelerations, exposed to weightlessness and radiation for different periods of time, and returned to Earth in safety. In order to substantiate the detailed knowledge of potentially adverse effects, many model experiments were launched using organisms which ranged from bacteria, plants, inverte brates, rodents and primates through to man. Although no immediate life threatening effects were found, these experiments can be considered today as the precursors to life science research in space. Many unexplained effects on these life forms were attributed to the condition of weightlessness. Most of them were poorly recorded, poorly published, or left simply with anecdotal information. Only with the advent of Skylab, and later Spacelab, did the idea emerge, and indeed the infrastructure permit, weightlessness to be considered as an ex tended tool for research into some fundamental mechanisms or processes as sociated with the effect of gravity on organisms at all levels. The initial hy pothesis to extrapolate from hypergravity through 1 x g to near 0 x g effects could no longer be retained, since many of the experiment results were seen to contradict the models or theories in the current textbooks of biology and physiology. The past decade has been dedicated primarily to exploratory research.

Download or read book Clinical Exercise Pathophysiology for Physical Therapy written by Debra Coglianese and published by Taylor & Francis. This book was released on 2024-06-01 with total page 1351 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to effectively examine, test, and treat patients with exercise, physical therapists need to understand how physiology from the cellular to the systems level provides the basis for normal responses to exercise. But that is not enough. Knowledge about pathophysiology, the changes that lead to abnormal responses to exercise in different patient populations, is also essential. Clinical Exercise Pathophysiology for Physical Therapy: Examination, Testing, and Exercise Prescription for Movement-Related Disorders is a comprehensive reference created to answer the “why” and the “how” to treat patients with exercise by offering both comprehensive information from the research literature, as well as original patient cases. Dr. Debra Coglianese, along with her contributors, have arranged Clinical Exercise Pathophysiology for Physical Therapy into three parts: foundations of physiological responses, pathophysiology of deconditioning and physiology of training, and pathophysiology considerations and clinical practice. The chapters present the physiology and pathophysiology for defined patient populations consistent with the American Physical Therapy Association’s Guide to Physical Therapy Practice. Patient cases also supplement each chapter to illustrate how understanding the content of the chapter informs physical therapy examination, testing, and treatment. The patient/client management model from the Guide to Physical Therapy Practice defines the structure of the patient cases, and the International Classification of Function, Disability, and Health (ICF) model of disablement has been inserted into each patient case. Highlighted “Clinician Comments” appear throughout each patient case to point out the critical thinking considerations. Included with the text are online supplemental materials for faculty use in the classroom. Clinical Exercise Pathophysiology for Physical Therapy: Examination, Testing, and Exercise Prescription for Movement-Related Disorders is a groundbreaking reference for the physical therapy student or clinician looking to understand how physiology and pathophysiology relate to responses to exercise in different patient populations.
