The sociology of the body and the sociology of knowledge have something in common: the matter of body knowledge. This category has been brought up initially by Polanyi (1966) and was developed further by Berger & Luckmann, Bourdieu, Soeffner, Schatzki and others. In the last years several publications in Germany  used it as an explicit focus of sociological analysis (Hirschauer, Knoblauch, Meuser). Body knowledge doesn’t indicate knowledge about the body (e. g. medical), and it implicates much more than mere craft knowing how (Ryle). The complex framework integrates intuition, construction of the world, sensual integration, unconscious adaptations, subjectivation, social meta-commentaries etc. Here, the phenomenological category of the lived body and the neurological term embodiment concept can be integrated (Nöe, Gallagher & Zahavi).

The case of Parkour can be used to revisit trendy sport theory (Schwier, Lamprecht & Stamm, Wopp, Breuer). Trendsport theory has not been developed especially for the explanation of Parkour. Partly the theory has to be revised in contact with the glocal movement of Parkour and its variations (Freerunning, Tricking, Parcouring). Parkour and the self-mediatization of sportive youth cultures make clear that there is a constantly shifting popular culture that makes enacted comments on urban surrounding, living conditions, social participation that affects passive recipients symbolically. The body is used as a discursive operator (Berthelot) and at the same time provides the basis for changes in identity constitution. Different variations of the scene work with different movement styles and aesthetic features in their video presentation at YouTube. Parkour in its original version implements a subversive commentary about urban city planning and regains it back to the people symbolically.

 The body knowledge of Traceures can be made explicit at least partly by the analysis of their activities, movements and performances. Urban materiality is consciously used quite different than the other passers-by use to behave.
