This book was released on 2011 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to examine the acute effects of underwater treadmill (UTM), body weight supported (BWS), and land treadmill (LTM) exercise on oxygen consumption (VO2), ratings of perceived exertion (RPE), and two-dimensional kinematics of the lower extremities during. Seventeen healthy and physically active male participants between the ages of 21 and 40 years performed an exercise bout for each mode of exercise. Each exercise bout lasted 7 min, consisting of 5 min of walking and 2 min of running and using the same self-selected treadmill walking and running speeds throughout all three conditions. The VO2, RPE, and kinematic data were collected during each exercise bout. The participants were submerged to the xiphoid process during the UTM exercise session and 20% of their body weight was unloaded using a Pneumax body weight support unloader for the BWS session. An ANOVA with follow-up multiple comparisons were used to determine significance differences (alpha = 0.05) among modes of exercise. Results revealed that VO2 values for LTM and BWS were 10% and 6% less (p

Download or read book Physiological and Perceptual Responses to Alternate Modes of Exercise at Self Selected Or Prescribed Intensity Between Overweight and Non overweight Individuals written by James Riley Galloway and published by . This book was released on 2016 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: To investigate the influence of body weight, exercise modality, and pace on physiological and perceptual responses during walking. Also, to determine if the relationship between physiological and perceptual responses was altered by modality, pace, or weight status. Methods: Aerobically untrained males (n=80, 22.85 ± 3.61 years) and females (n=80, 21.18 ± 1.52 years) classified as either overweight or non-overweight participated. Individuals completed two sessions separated by 72 hours. Session 1 included familiarization, whole body DXA scan, treadmill test to exhaustion, and a 70 foot walk test to determine self selected walking speed. For session 2, participants were randomly assigned to an exercise condition for a one mile walk (track at self selected intensity, treadmill at self selected intensity, track at prescribed intensity, treadmill at prescribed intensity) while physiological, perceptual, and metabolic parameters were collected. Results: Factorial ANOVA controlling for sex showed at prescribed pace, the track increased blood lactate significantly from pre to post-exercise when compared to the treadmill. Prescribed pace produced a greater increase in blood lactate from pre to post-exercise compared to self selected pace. Prescribed pace resulted in greater increases in blood pressures, longer heart rate recovery, greater average oxygen consumption, higher average and final heart rates, and higher energy expenditure during exercise (kcal/min). Overweight individuals showed higher values for final heart rate, percentage of maximal heart rate worked, and total energy expenditure. Greater perceived effort and higher pain ratings were seen on the treadmill and at prescribed pace. The variation in RPE responses during prescribed pace was found to be significantly greater than the self selected exercise. Conclusion: A novel finding of this study was the increased physiological stress and perception of effort during prescribed pace exercise and on the treadmill while total energy expenditure showed no significant differences. This could indicate an unfavorable perception and less affective response to the treadmill. With energy balance as a primary concern with overweight and obese populations, these results indicate that exercise at self selected pace in the preferred environment promotes an enjoyable experience with similar health benefits as those seen during exercise at prescribed higher intensity.
Download or read book Educating the Student Body written by Committee on Physical Activity and Physical Education in the School Environment and published by National Academies Press. This book was released on 2013-11-13 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.
Download or read book Physiological and Pathological Responses to Hypoxia and High Altitude written by Rodrigo Iturriaga and published by Frontiers Media SA. This book was released on 2020-06-22 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The appearance of photosynthetic organisms about 3 billion years ago increased the partial pressure of oxygen (PO2) in the atmosphere and enabled the evolution of organisms that use glucose and oxygen to produce ATP by oxidative phosphorylation. Hypoxia is commonly defined as the reduced availability of oxygen in the tissues produced by different causes, which include reduction of atmospheric PO2 as in high altitude, and secondary to pathological conditions such as sleep breathing and pulmonary disorders, anemia, and cardiovascular alterations leading to inadequate transport, delivery, and exchange of oxygen between capillaries and cells. Nowadays, it has been shown that hypoxia plays an important role in the genesis of several human pathologies including cardiovascular, renal, myocardial and cerebral diseases in fetal, young and adult life. Several mechanisms have evolved to maintain oxygen homeostasis. Certainly, all cells respond and adapt to hypoxia, but only a few of them can detect hypoxia and initiate a cascade of signals intended to produce a functional systemic response. In mammals, oxygen detection mechanisms have been extensively studied in erythropoietin-producing cells, chromaffin cells, bulbar and cortical neurons, pulmonary neuroepithelial cells, smooth muscle cells of pulmonary arteries, and chemoreceptor cells. While the precise mechanism underpinning oxygen, sensing is not completely known several molecular entities have been proposed as possible oxygen sensors (i.e. Hem proteins, ion channels, NADPH oxidase, mitochondrial cytochrome oxidase). Remarkably, cellular adaptation to hypoxia is mediated by the master oxygen-sensitive transcription factor, hypoxia-inducible factor-1, which can induce up-regulation of different genes to cope the cellular effects related to a decrease in oxygen levels. Short-term responses to hypoxia included mainly chemoreceptor-mediated reflex ventilatory and hemodynamic adaptations to manage the low oxygen concentration while more prolonged exposures to hypoxia can elicit more sustained physiological responses including switch from aerobic to anaerobic metabolism, vascularization, and enhancement of blood O2 carrying capacity. The focus of this research topic is to provide an up-to-date vision on the current knowledge on oxygen sensing mechanism, physiological responses to acute or chronic hypoxia and cellular/tissue/organ adaptations to hypoxic environment.

Available in PDF, EPUB and Kindle. Book excerpt: “This book gives a nice summary of the current state of diagnosis, treatment, and prevention of bone stress injuries. It is particularly useful for sports medicine fellows and residents with an interest in athletes and active patients." ---Doody's Review Service, 3 stars Bone stress injuries are commonly seen in athletes and active individuals across a full spectrum of physical activity, age, and gender. While most overuse injuries can be addressed through non-operative care, injuries may progress to full fractures that require surgery if misdiagnosed or not correctly managed. Written by leaders in sports medicine including physical medicine and rehabilitation, orthopaedics, endocrinology and allied health professionals of biomechanics, physical therapy and dietetics, Bone Stress Injuries offers state-of-the-art guidelines and up-to-date science and terminology to practitioners. Using a holistic approach to understand the management of bone stress injuries, this book highlights specific considerations by injury, gender, and risk factor to ensure that a comprehensive treatment plan can be developed to optimize bone health, neuromuscular re-education, gait mechanics, and injury prevention. Organized into four parts, opening chapters cover the general need-to-know topics, including clinical history, imaging, and risk factors including biological and biomechanical factors. The book proceeds anatomically through the body from upper extremity to foot and ankle injuries, with each chapter underscoring diagnostic and treatment strategies specific to that region. Chapters dedicated to special populations discuss the differences in injury evaluation and management according to age, gender, and military background. Final chapters review the prevention of injuries and examine both common and novel treatment strategies, such as medications, nutrition, gait retraining, orthobiologics, and other interventions. Invaluable in its scope and approach, Bone Stress Injuries is the go-to resource for sports medicine physicians, physiatrists, and primary care providers who manage the care of athletes and individuals leading active lifestyles. Key Features: Promotes evidence-based practice for diagnosis, treatment, and prevention of bone stress injuries Covers specific anatomy that is prone to bone stress injuries with dedicated chapters on upper and lower extremities, pelvis and hip, spine, and foot and ankle Considers evaluation and management differences according to specific populations of pediatric, male, female, and military personnel Discusses emerging strategies to treat bone stress injuries, such as gait retraining, orthobiologics, and other non-pharmacological treatments

Download or read book Fitness Measures and Health Outcomes in Youth written by Institute of Medicine and published by National Academies Press. This book was released on 2012-12-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical fitness affects our ability to function and be active. At poor levels, it is associated with such health outcomes as diabetes and cardiovascular disease. Physical fitness testing in American youth was established on a large scale in the 1950s with an early focus on performance-related fitness that gradually gave way to an emphasis on health-related fitness. Using appropriately selected measures to collected fitness data in youth will advance our understanding of how fitness among youth translates into better health. In Fitness Measures and Health Outcomes in Youth, the IOM assesses the relationship between youth fitness test items and health outcomes, recommends the best fitness test items, provides guidance for interpreting fitness scores, and provides an agenda for needed research. The report concludes that selected cardiorespiratory endurance, musculoskeletal fitness, and body composition measures should be in fitness surveys and in schools. Collecting fitness data nationally and in schools helps with setting and achieving fitness goals and priorities for public health at an individual and national level.
