Science comes to life with Practical Guide to Exercise Physiology, Second Edition. Taking an application-based approach, supported by vivid medical illustrations, this book provides students and health and fitness professionals with a simple and straightforward way to learn the fundamentals of human physiology, metabolism, and nutrition. Intricate physiological processes responsible for how the body responds and adapts to physical activity are described in an accessible manner so that readers can easily select appropriate training programs and explain them to others. Practical Guide to Exercise Physiology, Second Edition, is complemented by medical artwork that puts these complex systems into a digestible visual context. These systems are then applied to real-world practice and training principles that are beneficial to specific body systems to achieve the desired results. Part I of Practical Guide to Exercise Physiology, Second Edition, reviews human physiology fundamentals, including muscles and muscle adaptation, bioenergetics, and the cardiorespiratory system.
