In this work we were done a prediction of barriers to physical exercise in 356 adolescents, aged between 11 and 17 years (M = 13,56; DT = 1,39), using it as a theoretical framework of the hierarchical model of motivation Vallerand for this, through questionnaires was measured: the perceived motivational climate involving the task of the parents, the incremental ability belief, the need for competence, intrinsic motivation and barriers to physical exercise. The structural equation modeling showed that the perceived motivational climate involving the task of the parents positively predicted incremental belief, this in turn positively predicted the need for competition, said mediator positively predicted intrinsic motivation and finally, the most self-determined motivation negatively predicted barriers to physical exercise. From the findings of this study highlight the importance of improve basic psychological need of competence to reduce the number of barriers perceived by the subjects at the time of physical exercise, and thus avoid the abandonment of the practice of physical and sporting teenagers.
