This chapter is based on research conducted in Sweden with young sports-active children participating in non-elite sports. The main focus was to explore the phenomenon of emotional abuse of children in sport from the perspective of the children and young athletes. The study is theoretically grounded in the new sociology of childhood and draws inspiration from the theory of different sports worlds within children's sport. This chapter explores young athletes perspectives about how negative emotions arise from emotionally abusive interactions during sports practice and the resulting effects on the child. Data were collected from semi-structured interviews with 15 girls and boys aged 12–18 involved in gymnastics, swimming, floorball, football and volleyball. The study found that emotional abuse takes different forms and involves both peers and coaches, often occurring in situations where the young athletes’ sport performance is displayed and evaluated. The emotionally abusive behaviour seems to have a range of harmful effects for the child. This chapter adds to the existing literature by examining how emotional abuse is expressed and experienced within non-elite youth sports, what forms of interaction contribute to the experience of negative emotions and what harmful effects it may have.
