The present paper attempts to synthesize two potentially important tasks for the theoretical and scientific evolution of Physical Education: overcoming the scientific ideology and considering thresholds that can achieve in his scientific discursivity. These arguments are proposed in relation to the doctoral thesis “Influential Ideas in the theory of Physical Education at the Faculty of Physical Education of the Universidad Pedagogica Nacional (Bogota) between 1975 and 2000”. The conception of Scientific Ideology is a proposal by Georges Canghuilem and the Thresholds of the scientific discursivity was proposed by Michel Foucault. However, such concepts not had been reflected on construction of the theoretical and scientific field of Physical Education, neither had been considered in the evolution of the theoretical construction of the faculties of Physical Education.
