Relation between knowledge and decision making in tennis players and its influence in sport expertise

This work tries to study nonsingle some of the cognitive factors implied in tennis, but to establish the existing relations between different fundamental cognitive factors as the knowledge and the decision making. Of this form, 12 tennis players of different skill level in variables like declarative and procedural knowledge (measured through questionnaires), decision making and execution (evaluated through systematic observation) have evaluated themselves. We can emphasize the relation observed between the knowledge (declarative and procedural), and decision making, emphasizing in greater measurement the one takes place between the procedural knowledge and decision making in service as in the game play, that raise the importance of the knowledge on the tactical and decisional aspects that tennis players develop during the game.
