The Routledge International Encyclopedia of Sport and Exercise Psychology integrates the topics of motor control, physical education, exercise, adventure, performance in sports, and the performing arts, in several important ways and contexts, drawing upon diverse cultural perspectives. More than 90 overarching topics have been systematically developed by internationally renowned experts in theory, research, and practice. Each contribution delves into a thematic area with more nuanced vocabulary. The terminology drawn upon integrates traditional discourse and emerging topic matter into a state-of-the-art two-volume set. Volume 1: Theoretical and Methodological Concepts is comprised of theoretical topic matter, spanning theories and terminology from psychology contextualized to sport and physical activity, sport psychology-focused theories, and expansive discussions related to philosophy of science and methodology. Volume 2: Applied and Practical Measures draws upon practical concepts that bridge theory and research and practice. Broader issues that extend beyond sport and physical activity participants are embedded within the entries, intended to augment physical, mental, and social well-being. This expansive encyclopedia is a must-have resource for all professionals, scholars, and students in the fields of sport psychology and sport science.
