Self-assessed tactical skills in elite youth soccer players: a longitudinal study

Self-assessed tactical skills were investigated among 191 youth soccer players from ages 14 through 18 playing in different field positions. On a yearly basis, all players completed the Tactical Skills Inventory for Sports with scales for attacking and defensive situations and for declarative and procedural knowledge. A model to assess whether tactical skills change over time in each field position was developed using multilevel analysis. The models indicated that defenders and midfielders did not improve their tactical skills, whereas attackers increased their tactical skills from ages 14 to 18 years. The representing part of tactical skills for defenders is Acting in Changing Situations, for midfielders Positioning and Deciding, whereas Knowing About Ball Actions was the qualifying factor for attackers. Possible explanations for these differences in tactical skills among elite youth soccer players are the selection procedures at a younger age and task-specific experiences.
