What are the conditions and characteristics that determine the realization of physical activity and sport in university students? In a case study, the structuring of these practices within the social micro-order of a university campus is approached through a historical and synchronic study using documentary methods (historical) and a survey. This work overcomes 'activism' prevailing in the studies of physical-sports habits, bringing contributions from other areas of study and using with a transformative approach the concepts of Pierre Bourdieu.
