Longitudinal perspective of autonomy support on habitual physical activity of adolescents

The evidence collected in the area of physical education indicates the need to continue to delve into the relationships and models that satisfy the basic psychological needs of the students and their consequences, in order to promote a high rate of physical activity. The aim of this study was to test the relationship between autonomy support, basic psychological needs and self-determined motivation with respect to enjoyment, intention towards practice and habitual physical activity. A sample of 717 students, aged between 13 and 19 years old was used. A longitudinal design was carried out with two measurement time points. The results indicated positive relationships for all model variables between the two measurement times. The results obtained are discussed with respect to the use of an interpersonal style to support autonomy in the academic context of physical education classes for the promotion of greater commitment and adherence to physical activity.
