What does it mean full participation of people with disabilities in \textquoteleftsports for all'? Beyond the right of access, the right of sharing can enrich the quality of participation in sport, overcoming segregation. But how can be guaranteed an \textquoteleftinclusive participation' that avoids the double risk of 'normalizing' integration or 'leftcharitable' integration? Beyond 'being among the others' or even 'doing with the others', people with disabilities should also have the possibility to \textquoteleftbe valued by the others' through the real recognition of their participation in this shared sport experience. This is not only a cultural shift, but also a technical challenge, especially to fill the persistent gap between the inclusive rhetoric and the inclusive practices really available to the people. We will explore then the key issue of the technicality of inclusive participation in sport, showing the interest of applying the principles of design for all to the architecture of sports rules.
