Physical and sports practices represent a dimension of the socialhistory of people with impairments that has become progressivelyvisible, yet still little studied. Through the reading of socio-historicaland sociological research on these practices, the author defends hercontention that the development, recognition and social visibilityof these individuals having been obtained by the sphere of “dis-ability sport” are based on the convergence of two “tool boxes”for innovation: the organization of athlete classification and the“technologization” of the impaired body. Both of these innovatorymechanisms are controversial and subject to continuous experi-mentation in “sport for the disabled”. The social world of “disabilitysport” having been decoded, it comes across as a practical utopia, a heterotopia.
