The present study seeks to investigate the reasons that lead High School students to lose interest in Physical Education classes. A survey was conducted, through a questionnaire composed of open and closed questions, with 191 students from three schools of different contexts, in order to understand and analyze the results, correlating with the theoretical content presented by different authors, seeking a reflection on the main reasons that cause the lack of interest in Physical Education classes. The subject is very questioned by its real meaning and the students, even the ones who like it, do not attribute value to it. It is concluded then that are intrinsic factors, linked to the student's personal taste, and extrinsic factors, such as structure, material, teacher/school, are the issues most pointed out by students, that when they do not value the contents, they lose interest in the classes.
