In this paper we present a qualitative analysis of the perceptions of 28 university professors related to the functions of the Physical Education. We focus on the transformational function of the inequalities of origin. Generally, the procedures of the applied analysis adhered to the fragmentation and articulation proposed by the "Grounded Theory." We conclude that the social transformational function of the Physical Education is related to a sense of duty to become a professional not yet settled. We establish several pedagogical principles centered in the requirement to revise its epistemological support.
