This book discusses the maximal power and capacity of the three major biochemical pathways - aerobic (oxygen consumption), anaerobic lactic (muscle lactate accumulation in absence of oxygen consumption), and anaerobic alactic (phosphocreatine hydrolysis) metabolism - as well as the factors that limit them. It also discusses the metabolic and cardio-pulmonary mechanisms of the dynamic response to exercise. The way and extent to which the power and capacity of the three major energy metabolisms are affected under a number of different conditions, such as training, hypoxia and microgravity, are also described.
Muscle and Exercise Physiology is a comprehensive reference covering muscle and exercise physiology, from basic science to advanced knowledge, including muscle power generating capabilities, muscle energetics, fatigue, aging and the cardio-respiratory system in exercise performance. Topics presented include the clinical importance of body responses to physical exercise, including its impact on oxygen species production, body immune system, lipid and carbohydrate metabolism, cardiac energetics and its functional reserves, and the health-related effects of physical activity and inactivity. Novel topics like critical power, ROS and muscle, and heart muscle physiology are explored. This book is ideal for researchers and scientists interested in muscle and exercise physiology, as well as students in the biological sciences, including medicine, human movements and sport sciences. - Contains basic and state-of-the-art knowledge on the most important issues of muscle and exercise physiology, including muscle and body adaptation to physical training, the impact of aging and physical activity/inactivity - Provides both the basic and advanced knowledge required to understand mechanisms that limit physical capacity in both untrained people and top class athletes - Covers advanced content on muscle power generating capabilities, muscle energetics, fatigue and aging
This book describes the evolution of ideas relating to the mechanism of muscular contraction since the discovery of sliding filaments in 1954. An amazing variety of experimental techniques have been employed to investigate the mechanism of muscular contraction and relaxation. Some background of these various techniques is presented in order to gain a fuller appreciation of their strengths and weaknesses. Controversies in the muscle field are discussed along with some missed opportunities and false trails. The pathway to ATP and the high energy phosphate bond will be discussed, as well as the discovery of myosin, contraction coupling and the emergence of cell and molecular biology in the muscle field. Numerous figures from original papers are also included for readers to see the data that led to important conclusions. This book is published on behalf of the American Physiological Society by Springer. Access to APS books published with Springer is free to APS members.
Abstract: This third edition of the book integrates basic concepts and relevant scientific information to provide the foundation for understanding nutrition, energy transfer, and exercise and training. Designed for both the beginning and advanced student, the subjects covered include energy for physical activity, systems of energy delivery and utilization, enhancement of energy capacity, work performance and environmental stress, body composition, energy balance, and weight control, and the metric system and SI units.
This volume describes the current state of our knowledge on the neurobiology of muscle fatigue, with consideration also given to selected integrative cardiorespiratory mechanisms. Our charge to the authors of the various chapters was twofold: to provide a systematic review of the topic that could serve as a balanced reference text for practicing health-care professionals, teaching faculty, and pre-and postdoctoral trainees in the biomedi cal sciences; and to stimulate further experimental and theoretical work on neurobiology. Key issues are addressed in nine interrelated areas: fatigue of single muscle fibers, fatigue at the neuromuscular junction, fatigue of single motor units, metabolic fatigue studied with nuclear magnetic resonance, fatigue of the segmental motor system, fatigue involving suprasegmental mechanisms, the task dependency of fatigue mechanisms, integrative (largely cardiorespiratory) systems issues, and fatigue of adapted systems (due to aging, under-and overuse, and pathophysiology). The product is a volume that provides compre of processes that operate from the forebrain to the contractile proteins.
The Science of Fitness: Power, Performance, and Endurance clearly explains the vital connection between diet and exercise in the human body. With this knowledge, you can use the right exercise and nutrition to obtain a higher quality life, prevent disease, and slow the aging process. Authored in a straightforward style and with color images throughout, this book explores the cellular science behind fitness, protein synthesis, and healthy living. With it you will learn the most recent and important discoveries in the relationships between physical fitness, nutrition, weight loss, and weight management. It provides key information on the body's mitochondrial processes and their role in aging, along with well-informed discussions on general nutrition, sports nutrition, exercise physiology, how to enhance athletic performance, and how exercise strengthens the mind. Whether you are interested in how to eat healthy, train for your first (or next) marathon, take your fitness to the next level, find the best super foods, or simply want to improve your vitality through healthy, doable practices, this book will help you on your journey regardless of age or fitness level. - Presents the connection between exercise, nutrition, and physiology in a way that is ideal for both experienced athletes and newcomers - Provides the scientific basis for mitochondrial functions and their relationship to fitness, protein synthesis, quality of life, and the aging process - Synthesizes the latest research on nutrition, sports nutrition, super foods, and the brain/body connection - Co-Authored by legendary cyclist Greg LeMond, who illustrates key points using his own athletic journey
This book offers a state-of-the-art description of the complexity of the healthy and pathological respiratory system, with particular reference to the mechanics of the airways, lung and chest wall. Detailed information is provided on new insights into the mechanics of breathing that have been obtained through technological innovations in measurement systems, cutting-edge modeling techniques and novel approaches to functional imaging of the respiratory system. It is explained how these advances permit the assessment of emerging treatment approaches, including new drugs, innovative surgical techniques and modes of mechanical ventilation and new forms of rehabilitation. In order to ensure comprehensive coverage of the subject, the editor has assembled a multidisciplinary team of authors comprising basic scientists in respiratory medicine, chest and intensive care physicians and bioengineers involved in both modeling and instrumentation. The book is intended for intensive care physicians, respirologists, physiologists, rehabilitation specialists, basic scientists in respiration, research and clinical fellows, biomedical engineers involved with respiratory mechanics and respiratory therapists. They will update their knowledge and improve their clinical expertise.
This 2001 book provides a practical and systematic approach to the acquisition, interpretation, and reporting of physiologic responses to exercise. Pulmonologists, cardiologists, and sports physicians, as well as respiratory therapists and other allied health professionals will find this book an indispensable resource when learning to select proper instruments, identify the most appropriate test protocols, and integrate and interpret physiologic response variables. The final chapter presents clinical cases to illuminate useful strategies for exercise testing and interpretation. Useful appendices offer laboratory forms, algorithms and calculations, as well as answers to FAQs. A glossary of terms, symbols, and definitions is also included. Exercise Testing and Interpretation: A Practical Approach offers clearly defined responses (both normal and abnormal) to over thirty performance variables including aerobic, cardiovascular, ventilatory, and gas-exchange variables. Practical, portable, and easy-to-read, this essential guidebook can be used as a complement to more detailed books on the topic, or stand on its own.
This volume is a comprehensive textbook for the undergraduate course in sports nutrition. Focusing on exercise physiology, this text is to be used in a certification course sponsored by the International Society of Sports Nutrition (ISSN).
