‘Literal torture’: Vulnerability, resilience and young people's experiences of pressure in physical education

British Educational Research Journal, EarlyView.
Abstract This paper combines vulnerability and resilience theory to explore the pressure young people experience in Physical Education (PE) and sport at secondary school. The theoretical framework was used to understand both how young people experience PE in school and how vulnerability and resilience function interdependently in social contexts like ...
