Harmonization and Implementation of Sports-related Concussion Guidelines in European Football for Youth - the Erasmus + Project

Inclusion Criteria: Clubs: Youth football clubs in the four countries will be invited to participate. Clubs must have: * The ability to implement new concussion protocols with support from the project team. This will include basic resources such as access to digital platforms (e.g., internet connectivity, devices to access training materials). * A willingness to engage with and integrate educational materials into their regular operations. Federations will support clubs in understanding these expectations before participation. Stakeholders: Key stakeholder groups involved in youth football will be included: * Coaches of youth teams, regardless of prior experience in concussion management. * Players actively participating in youth football (targeting diverse age groups and genders). * Parents of youth players to ensure comprehensive inclusion of perspectives. * Referees involved in officiating youth football matches. * Medical personnel, including team doctors and physiotherapists. Exclusion Criteria: * Clubs that lack the basic resources or logistical capacity to access digital learning platforms or implement concussion protocols (as determined by federations). * Stakeholders who are unwilling to participate or unable to provide informed consent (or, for minors, parental/guardian consent).
