This article focuses on the discourses dealing with sport (political, institutional, Olympic, etc.) as well as speeches from sports practices (forums, social networks and applications dedicated to sport), in order to question the values of Olympism and how they are put into discourse and polarised. The corpus is composed of major institutional texts (charts and codes essentially). Its study is complemented by the analysis of a second corpus comprising ‘posts’ distributed on sports forums and social networks as well as publications relating to the Strava community. We describe how the texts governing Olympism formulate an instituting topical topic, and how the meaning of values evolves through discursive updating, in contexts referring to the practice of amateur sport. In particular, we question Respect, Friendship and Excellence (the three core values claimed by the Olympism movement) and their links with other values (peace among peoples, equality, solidarity, integrity). Discursive analysis in situ makes it possible to identify the stakes of the reconfiguration of these fundamentals in the digital practices of amateurs, around fair play, performance, and more generally what is understood by “values of sport”.
