The aim of this study was to assess the relationships among the motivational profile, the coach’s interpersonal style and the intention to be physically active in young athletes. A sample of 254 athletes (mean age of 12.81 years), who used to participate in official competitions, was used. The measurements taken were of the young athletes’ perception of the interpersonal style of the coach, satisfaction of basic psychological needs, motivation towards sports practice and intention to be physically active. Bivariate correlation, cluster and multivariate analyses were carried out. The cluster analysis revealed two profiles: one with high self-determined motivation and greater values of autonomy support, competence, relatedness and intention to be physically active, and another less self-determined cluster that showed low levels of competence, relatedness and intention to be physically active. It is suggested that adding some strategies based on autonomy support to training with athletes may ensure adherence to sports practice.
