其他摘要：The aims of this research were, based on Self Determination Theory, to go further into the relationship between different cognitive and motivational variables that affect players’ performance in training stages and to know their predictive power on performance. The study sample was composed of 134 U-16 volleyball players. The studied variables were: motivational (motivation and basic psychological needs), cognitive (procedural knowledge and decision making), and performance. The results showed a relationship between motivational and cognitive variables. Specifically, procedural knowledge correlated positively with intrinsic motivation and basic psychological needs of relatedness and competence and negatively with amotivation. Cognitive variables were the main predictors of players’ performance. Intervention is suggested in order to improve cognitive processes due to their relevance in performance in volleyball training stages, taking into account motivational skills because of their relevance in players’ formative process.
