"The figures relating to gender-based violence (among others) in Europe are shocking, whatever the countries, regions or even the social or cultural groups concerned. This violence poses a huge challenge in the area of ​​human rights. In the context of sports, this phenomenon is recurrent, trivialized or passed over in silence, whether one is amateur or professional, young or adult.Indeed, sports and physical activities in general constitute, like all human activity, potential vectors of violent behaviour of all kinds. Racist, sexist, homophobic or physical insults are extremely widespread and recognized in sports. In this context, certain populations suffer more particularly from violence and more generally from prejudice: women, persons with a disability and homosexuals, whether or not they are declared (including transgender and LGBTQIA +).To fight against this scourge, we wanted to combine our knowledge, skills and experiences to use them to the greatest number by building this educational kit.This work seems necessary, or perhaps, essential as this theme is not (or barely) addressed in current training spaces (formal or informal) of young people and adults working in physical and sporting activities. However, it seems undeniable to us that these learning spaces provide an opportunity as privileged places to understand, analyse and build good practices. The change of behaviours occurs through a change of mentality, this is why it is important to invite reflection and awareness through pedagogical methods and animation tools based on action, observation, meeting, dialogue and play.To prevent, educate and combat this violence, we wanted to establish a partnership based on diversity and complementarity. Thus this project is supported by a popular education association (France), and two martial arts sports associations specializing in the inclusion of the most vulnerable and in particular our target audiences (Ireland and the United Kingdom). This diversity responds to our main objective, which is the construction of an educational kit for volunteers and professionals in animation, sport and education (formal or not). Indeed, each partner carries out actions on its territory and the objective is to enhance them and to unite these experiences to make the case. The intercultural tools and methods offered will be the fruit of an exchange of experiences, practices and theoretical reflections. The purpose of the briefcase is to give volunteers and professionals an easy-to-use tool to educate and prevent violence against our target audience in the context of physical and sports activities. Likewise, it is a question of developing their skills and enabling them to train other youth workers, trainers and sports actors in the treatment of violence among young sportsmen and women in the context of non-formal education.At the same time, throughout the project, our young athletes will benefit from thematic workshops carried out in each country, as well as transnational learning activities to help them understand and act against this violence. They will be able to meet their European counterparts and debate with them on our working themes. These meetings will combine reflection through new thematic workshops and action through self-defence activity initiation sessions.These meetings, via the diversity of participants (women victims of violence, physical disability and persons with a learning disability, autism and LGBTQIA +), will allow them to confront the ""Otherness"" from oneself of the person who is socially excluded (consciously or not) due to the ignorance of his lived reality.These meetings will help them to get to know the ""Other"" better and to become more aware of their own prejudices and stereotypes and, by that very fact, of the violence suffered and / or exerted.On a daily basis, this will help them gain more self-confidence and self-esteem through martial arts and self-defence activities whilst developing their individual and collective empowerment.They can also use the activities offered and/or if more appropriate, the more theoretical content to increase their knowledge of the subject. They can share this with their sports and sports colleagues, friends, families, etc.At the end of the project, they too will become Ambassadors (formal or not) of Non-violence in Sport."
