The third edition of this book continues to provide a thorough yet succinct introduction to the basic principles of exercise and sport physiology. Its applied perspective is designed to help future physical educators, coaches, physicians'' assistants, physical therapists, exercise scientists, and exercise professionals understand and appreciate the scientific foundations of exercise and sport. Written in a clear, understandable style, this book will be a useful resource for a variety of applications, including developing appropriate unit plans for physical education classes, organizing effective practice sessions for athletes, prescribing safe and productive training programs, or preparing for certification or licensure. It provides a basic introduction to systems of the human body and covers important scientific and applied aspects of exercise and sport physiology. The authors carefully designed the material to be covered easily in one semester, in an introductory course, but the book can also serve as a foundation for advanced courses. Its 16 lab experiences are matched to relevant chapters and complement the topics covered; they allow readers to apply physiological principles to exercise and sport, provide opportunities for hands-on learning and application of the scientific principles, and often don''t require complex equipment.
