This book discusses the urgent need for a social relevance perspective for physical education and sport and is designed for students beginning professional preparation in physical education and sport, practitioners, or students wishing to round out their general education. An introductory statement, written by Laura J. Huelster, explores the historical background and present status of the field. The book then focuses on human motor performance in sport, dance, and exercise. The first five chapters present the fundamental disciplinary areas of the profession: "Background, Meaning, and Significance" (Harold J. VanderZwaag); "Functional Effects of Physical Activity" (James S. Skinner); "Sociocultural and Behavioral Aspects" (A. V. Carron); "Motor Learning and Development" (G. Lawrence Rarick); and "Mechanical and Muscular Human Function" (Glynn A. Leyshon). The last three chapters include the various concurrent subsumed professional components: "Management Theory and Practice" (Daniel G. Soucie); "Program Development" (Ann E. Jewett); and "Measurement and Evaluation" (B. Don Franks). The book concludes with a chapter that summarizes, draws conclusions, and makes predictions for the future. (JD)
