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.

This book was released on 1992-02-01 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book surveys the entire field of body composition as it relates to performance. It includes a clear definition of terminology and a discussion of the various methods for measuring body composition. The authored papers represent a state-of-the-art review of this controversial field and address questions such as: What is a better measure of body compositionâ€"body fat or lean body mass? Does being overweight for one's height really affect performance? The book also addresses the issue of physical appearance as it relates to body fatness and performance. It includes an in-depth discussion of many of the topics of interest to those involved in sports medicine and exercise physiology.
Download or read book Skeletal Muscle Circulation written by Ronald J. Korthuis and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 147 pages. 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of fitness and body composition standards in the U.S. Armed Forces has always been to select individuals best suited to the physical demands of military service, based on the assumption that proper body weight and composition supports good health, physical fitness, and appropriate military appearance. The current epidemic of overweight and obesity in the United States affects the military services. The pool of available recruits is reduced because of failure to meet body composition standards for entry into the services and a high percentage of individuals exceeding military weight-for-height standards at the time of entry into the service leave the military before completing their term of enlistment. To aid in developing strategies for prevention and remediation of overweight in military personnel, the U.S. Army Medical Research and Materiel Command requested the Committee on Military Nutrition Research to review the scientific evidence for: factors that influence body weight, optimal components of a weight loss and weight maintenance program, and the role of gender, age, and ethnicity in weight management.

Download or read book Anthropometrical and Physiological Observations on Obese and Non obese Young Men Undergoing a Program of Vigorous Physical Exercise written by Jerry A. Dempsey and published by . This book was released on 1963 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven young men, differing markedly in body fat content, were tested at the beginning and end of consecutive periods of: daily training (8 weeks), voluntary training (5 weeks), and daily training (5 weeks). Body composition was assessed by means of water immersion densitometry, skin- fold fat measures, and both gross and fat-corrected body dimensions. Basal oxygen consumption, muscular strength, and the Balke treadmill test of sub-maximal work capacity were also measured. Caloric consumption over the entire 18 weeks, and physical activity during the period of voluntary activity, were recorded daily. The following changes were observed, within the limitations of measurement, in subjects undergoing daily training. Weight losses in initially overweight men were composed of increase in fat-free body weight and muscular mass, and decreases in skinfold and total body fat. One very thin subject increased his gross body weight entirely through a gain of fat-free body weight and muscle mass, while body fat remained constant. These changes were not evidenced during the period of reduced activity. Total proportional strength increased and decreased with training and detraining respectively, and was not directly dependent upon body mass or body composition. Basal oxygen intake increased per unit of weight and decreased per unit of fat-free body weight. The former change was partially accounted for by an increase in muscle mass, while the latter was attributed, primarily, to a decrease in body fat. Treadmill performance time improved irrespective of initial values and improvements were retained over the period of decreased activity. In 36 relatively sedentary young men, five measures of body mass and body composition were found (multiple regression analysis) to account for 52.21 per cent of the total interpersonal variance in treadmill performance time. Relative obesity or per cent body fat accounted for the majority (23.87%) of the variance and was significantly related to performance time with the effect of gross body weight partially out (r = -.603). The relationships between these variables were somewhat reduced in subjects who had undergone a daily program of vigorous exercise. The present findings are in agreement with previous clinical and laboratory observations which have associated obesity with an accumulation of excess body fat as well as subnormal levels of cardio-vascular performance, muscular strength and basal metabolism. It was further evidenced that a progressive program of vigorous, physical exercise contributed to the therapy of obesity by: a) specifically or independently changing each of the above parameters, and b) rendering changes in certain aspects of body composition which in turn contributed to improvements in the selected physiological variables.
