This research project aims to study the relationships and experiences of young people in sport. These relationships and experiences can be built around camaraderie, mutual support and shared interests. However, they can also be marked by power dynamics and abusive behaviour, exposing some young people to various forms of violence (physical, psychological, sexual, instrumental, etc.). This violence may be perpetrated by adults (parents or trainers, instructors, teachers, coaches, etc.) or by other young sportspeople. Scientists still know very little about the relationships and experiences of young people, particularly minors, and the violence that can occur in organised sport in Switzerland and the Canton of Vaud. The aim of this project is to fill this gap by studying the situation in the Canton of Vaud.
