Book Fitness Measures and Health Outcomes in Youth

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.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

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.

Book The Influence of Training on the Maximum Oxygen Uptake and Endurance Capacity of Male and Female Subjects

Download or read book The Influence of Training on the Maximum Oxygen Uptake and Endurance Capacity of Male and Female Subjects written by Philippa K. Bland and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Many consider that maximum oxygen uptake (VO2 max) provides a valid measure of fitness in general and endurance capacity in particular. However, in recent years evidence has accumulated suggesting that VO2 max values provide only limited information regarding endurance capacity. This study set out to investigate the influence of training on the maximum oxygen uptake and endurance capacity of male and female subjects. The investigation consisted of three studies. The first described the relationship between VO2 max correlation between VO2 max and Z individuals within the group with differently. The second study examined the influence of short term training on VO2 max and endurance capacity. The increase in VO2 max was small (7%) when contrasted with the large improvement in endurance capacity (478%). The above two studies both indicated that VO2 max alone does not determine endurance capacity. The third study therefore set out to examine which factors influence changes in VO2 max and endurance capacity after a period of endurance training. By adopting a single-leg exercise model (Davies and Sargeant, 1975), this study not only re-examined the relationship between VO2 max and endurance capacity but also attempted to separate local and central adaptations to training. This model was adopted because of the suggestion that increases in endurance capacity are the result of changes in the skeletal muscle (local) (Gollnick et al., 1973). Again, the increases in VO2 max were small when compared with the improvements in endurance capacity. Improvements in the trained leg (TL) were attributed to central and local adaptations to training and in the untrained leg (UTL) to central cardiovascular changes. The large increase in the endurance capacity of the TL (523%) was 404% greater than that seen in the UTL, thus supporting the view that increases in endurance capacity are largely the result of changes in the skeletal muscle rather than improvements in the central cardiovascular system. The findings of this study clearly demonstrate that VO2 max is a poor predictor of endurance capacity. It provides no information regarding an individuals ability to endure exercise, i.e. the ability to sustain a given submaximal work load, both before and after training. It is suggested that the fitness of an individual may be reflected not by their V02 max value but rather by the largest fraction of that value which he or she can utilize during prolonged periods of exercise.
