The importance of supporting student autonomy in physical education classes to improve intention to be physically active

Abstract

This study sought to analyze the predictive power of supporting student autonomy in physical education classes on the intention to be physically active based on motivational variables. The Self-Determination Theory was used as a theoretical framework. The study sample comprised 922 students of both sexes, aged between 14 and 18 years old (M = 14.95, SD = 0.98). Several questionnaires were applied to analyze the measured variables. The results of the model of structural equations revealed that students' perceived autonomy support positively and significantly predicted the satisfaction of the BPN (autonomy, competence and social relations). These, in turn, positively and significantly predicted autonomous motivation; and lastly, the most self-determined type of motivation positively and significantly predicted the intention to be physically active. This finding emphasizes the importance of establishing motivational strategies to support students' autonomy via the satisfaction of psychological needs, enhancing autonomous motivation and, as a consequence, increasing students' intention to practice physical activity.
