Book excerpt: International Perspectives on Key Issues in Sport and Exercise Psychology is a series of edited books, with a global focus, which reflect the state of art in areas of current and emerging interest in the study of sport and exercise psychology. Each volume in the series contributes to the better understanding of a key issue facing researchers and practitioners in sport psychology. This volume in the series focuses upon the sociocultural issues that challenge and often undermine participation, performance, and well-being in sports. Contributors address a number of important issues, such as exclusion, miscommunication, and ineffective practice in sport. The book extends the recent interest in culture within sport psychology by using a critical approach to highlight less mainstream sports such as martial arts, circus arts, extreme sports, and dance, and it will help sports participants and social scientists to gain an understanding of these marginalized sporting identities. By highlighting "subcultural" contexts, with their individual practices and values, it is hoped that the volume will promote the goal of achieving a more just, inclusive, and ethical sport psychology. The Psychology of Sub-Culture in Sport and Physical Activity will be ideal reading for sport and exercise academics and practitioners, advanced students of applied sport psychology, and related fields such as sport science, critical studies, sociology, cultural studies and social anthropology.
