Abstract

The aim of this research was to evaluate the performance and tactical behavior of youth soccer players of teams from base categories. The sample consisted of 152 male soccer players aged 11-17 years who participated in the in the U-13 (n = 50), U-15 (n = 62) and U-17 (n = 40) Sergipe State Championship in the year 2015. The System of Tactical Assessment in Soccer (FUT-SAT) was used to identify the players’ tactical behavior based on the fundamental tactical principles. The main results of the study show that players presented higher tactical offensive performance (50.8 ± 9.8 points) compared to defensive performance (34.3 ± 5.7 points) (p < 0.001; d = 2,1), and the Depth Mobility principle presented the highest performance indices in the offensive phase (64.1 ± 8.7; F = 54.4; p < 0.001; partial ƞ² = 0.26). Defensive Coverage showed the highest performance indexes in the defensive phase (46.1 ± 24.3; F = 54.4; p < 0.001; partial ƞ² = 0.26).

Offensive Phase (team with ball possession)
Penetration		Tactical action performed with ball possession. The player seeks to break through the cross lines of the opposing team and consequently advance on the opponent’s playing field towards the goal.
Offensive Coverage		Offer of support to the player with the ball within or near the game center in search of numerical superiority in ball possession by reducing opponents’ defensive pressure.
Depth Mobility		Tactical action that allows the team to play in depth through increasing effective game space.
Width and Length		Tactical action that can be performed with and without ball possession. Without ball possession, the player offers pass lines to the player with the ball in breadth and depth. With ball possession, it consists of actions taken towards the goal itself or on the side of the field in order to gain time in decision making.
Offensive Unity		Tactical action that allows the team to play in cohesion by performing compact attacks from reduced distances between the team’s cross lines.
Defensive Phase (team without ball possession)
Delay		Primary opposition to the player with the ball within the game center, avoiding their advancement on the game field in addition to blocking pass lines.
Defensive Coverage		Secondary opposition to the player with the ball within the game center, in order to provide balance in the actions of the player who carries out the tactical contention principle.
Concentration		A tactical action aimed at maximum protection of the goal itself by conditioning the opponent to areas of the game field that offer less risk to the team.
Balance		Tactical action to maintain defense security by covering pass lines offering guarantee to players who perform contention and defensive coverage.
Defensive Unity		Tactical action that allows the team to defend itself as a whole, keeping defensive compression through the distance between the team’s own cross lines.
