This study deals with the concept of an expanded curriculum in Physical Education and Davidov and Leontiev's teaching theory as a possibility for objectifying human formation from an omnilateral perspective. We argue that the treatment of knowledge, school systematisation and the standardisation of school practices need to be based on a concept of an expanded curriculum. In this endeavour, Physical Education is included, understanding body culture as its object of study, in other words, as historical human production. The expanded curriculum is a possibility for the theoretical-methodological development of Davidian teaching theory in the school environment. Students will be engaged in study activities, which will allow them to develop their potential, which is not given a priori. Potentialities for appropriating the totality of man's productive capacities and, at the same time, access to the totality of capacities for consumption and satisfaction, above all enjoying spiritual goods as well as material ones, from which he is excluded as a result of the technical division of labour.
