Download or read book Sex Differences in the Oxygen Uptake Kinetic Response to Moderate Intensity Exercise in Obese Adolescents written by Mary Bowen and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The oxygen uptake (VO2) kinetic response to exercise provides insight into aerobic performance and the efficiency of the body to maintain oxygen demand during the initiation of exercise. Previous research in normal weight children reports insignificant differences in gender VO2 on-kinetic responses to moderate exercise. No study has evaluated the impact obesity may have on gender VO2 on-kinetics. PURPOSE: To determine if sex differences exist in the VO2 kinetic response to moderate exercise in obese adolescents. METHODS: Male (n=16) and female (n=39) adolescents completed a graded exercise test to exhaustion on a treadmill. Data from initial 4-min treadmill walking was used to determine a time constant. RESULTS: The time constant was significantly different (P=0.009) between obese male and female adolescents (15.42 [plus or minus] 7.31 s vs. 22.03 [plus or minus] 8.56 s, respectively). CONCLUSION: Sex differences exist in VO2 on-kinetics during moderate exercise in obese adolescents indicating an enhanced potential for males to deliver and/or utilize oxygen.

Download or read book Sex Differences in Hemodynamic Response to High Intensity Interval Exercise written by Leah Coe and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex differences in the cardiorespiratory and hemodynamic response to exercise exist due to differences in heart size, blood volume, and hemoglobin mass, eliciting a higher maximal oxygen uptake (VO2max) in men versus women. Data are equivocal on whether sex differences in training responsiveness occur. This study investigated potential sex differences in the hemodynamic response (stroke volume (SV) and cardiac output (CO)) to high intensity interval exercise (HIIE). Habitually active men (n=15) and women (n=13) underwent VO2max testing, followed by three HIIE sessions consisting of the 4X4, 10X1, and reduced exertion high intensity training (REHIT), whose order was randomized. During exercise, oxygen uptake (VO2) and hemodynamic responses were determined. Results showed no sex difference in peak relative VO2 (p=0.263), CO (p=0.277), or SV (p=0.116), although absolute values were higher in men (p0.05). Peak absolute (127.3 ± 20.6 vs. 115.2 ± 16.6 mL/beat, p=0.004, d=0.66) and relative SV (111.0 ± 15.5 vs. 100.7 ± 11.1 %max, p=0.005, d=0.78) were higher with REHIT versus 4X4. No sex differences in mean relative VO2, CO, or SV occurred (p0.05). Data showed lower mean VO2 during REHIT versus 4X4 (59.3 ± 6.8 vs. 65.8 ± 5.8 %VO2max, p

Download or read book The Young Athlete written by Helge Hebestreit and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This essential new volume in the Encyclopaedia of Sports Medicine series, published under the auspices of the International Olympic Committee, provides a thorough overview of the unique physiologic characteristics, responsiveness to training, and possible health hazards involved in the training, coaching, and medical care of young athletes. Intense involvement in competitive sports often begins during childhood. During adolescence, many athletes reach their peak performance and some may participate in World Championships and Olympic Games at a relatively young age. The Young Athlete presents the available information relevant to exercise and training in youth, reviewed and summarized by authors who are recognized as leaders in their respective fields. The Young Athlete is subdivided into seven parts covering: the physiologic bases of physical performance in view of growth and development; trainability and the consequences of a high level of physical activity during childhood and adolescence for future health; the epidemiology of injuries, their prevention, treatment, and rehabilitation; non-orthopedic health concerns including the pre-participation examination; psychosocial issues relevant to young athletes; diseases relevant to child and adolescent athletes; the methodology relevant to the assessment of young athletes. This valuable reference summarizes a large database of information from thousands of studies and is especially relevant to sports physicians, pediatricians, general practitioners, physical therapists, dietitians, coaches, students, and researchers in the exercise sciences.

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 Pulmonary Gas Exchange written by G. Kim Prisk and published by Biota Publishing. This book was released on 2013-08-01 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lung receives the entire cardiac output from the right heart and must load oxygen onto and unload carbon dioxide from perfusing blood in the correct amounts to meet the metabolic needs of the body. It does so through the process of passive diffusion. Effective diffusion is accomplished by intricate parallel structures of airways and blood vessels designed to bring ventilation and perfusion together in an appropriate ratio in the same place and at the same time. Gas exchange is determined by the ventilation-perfusion ratio in each of the gas exchange units of the lung. In the normal lung ventilation and perfusion are well matched, and the ventilation-perfusion ratio is remarkably uniform among lung units, such that the partial pressure of oxygen in the blood leaving the pulmonary capillaries is less than 10 Torr lower than that in the alveolar space. In disease, the disruption to ventilation-perfusion matching and to diffusional transport may result in inefficient gas exchange and arterial hypoxemia. This volume covers the basics of pulmonary gas exchange, providing a central understanding of the processes involved, the interactions between the components upon which gas exchange depends, and basic equations of the process.

Available in PDF, EPUB and Kindle. Book excerpt: "In this fifth edition of Principles of Exercise Testing and Interpretation, as in earlier editions, we attempt to develop conceptual advances in the physiology and pathophysiology of exercise, particularly as related to the practice of medicine. The underlying theme of the book continues to be the recognition that the most important requirement for exercise performance is transport of oxygen to support the bioenergetic processes in the muscle cells (including, of course, the heart) and elimination of the carbon dioxide formed as a byproduct of exercise metabolism. Thus, appropriate cardiovascular and ven- tilatory responses are required to match those of muscle respiration in meeting the energy demands of exercise. As depicted by the logo on the book cover, normal exercise performance requires an efficient coupling of external to internal (cellular) respiration. Appropriate treatment of exercise intolerance requires that patients' symptoms be thought of in terms of a gas exchange defect between the cell and the environment. The defect may be in the lungs, heart, peripheral or pulmonary circulations, the muscles themselves, or there may be a combination of defects. Thus, we describe the pathophysiology in gas transport and exchange that affect any site in the cardio- respiratory coupling between the lungs and the muscles. We illustrate how cardiopulmonary exercise testing can provide the means for a critical evaluation by the clinician-scientist of the functional competency of each component in the coupling of cellular to external respiration, including the cardiovascular system. To achieve this, clinical cases are used to illustrate the wide spectrum of pathophysiology capable of causing exercise intolerance"--Provided by publisher.

This book was released on 2002-07-19 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.
