Based on an extensive national research project with global relevance, this pioneering volume draws on unique data on bullying in youth sports training collected from both athletes and coaches using a variety of methodological approaches. Nery, Neto, Rosado and Smith use this research to establish a baseline of the prevalence of bullying among young male athletes, offering evidence-based strategies for prevention and providing a solid theoretical basis for the development of anti-bullying intervention programs. Bullying in Youth Sports Training explores how often bullying occurs, how long it lasts, where and when bullying takes place, the coping strategies used by victims, and the individual roles of victims, bystanders and bullies. It provides new insights into theories of youth sport bullying and highlights the particular characteristics specific to bullying in sport. The backgrounds of bullies and victims are also explored, as well as the consequences and practical implications of sustained bullying. The book provides both theoretical and practical approaches to bullying in youth sport training, providing anti-bullying guidelines based on the results of the research. The book is essential reading for scholars and students in child development and sport sciences as well as sports coaches and professionals in mental health, education and social work.
