How to prevent violence with young people at risk? Do sports at risk can restore social link and transform behaviour with this kind of population? That’s the aim of an association into the town of Roubaix in the north of France, far from Lille through free fighting and scaling. Through this communication, we will show which means of collaborations, which sportive actions they used with success since thirty years now. We ‘ill try to restore their specific pedagogical method they built since thirty years ago. At least, which are their impact about social including and behaviour, specially health and sport training? For that we use a sociological and pedagogical theoretical framework, We use it to analyse which mean these young people attribute to the rules (about sports, behaviour, security, ) they do respect.

It’s a comparative research for three years, at the beginning we‘ll use three kinds of methods: interviews with the director of the association, two educators. We built a questioner which asks the population on five themes: Later we’ll have interviews to complete our results.

It was passed for the first time in 2008, we presents some results about these first population.
