Purpose
The aim of this study was to analyze the execution efficiency of core tactical principles in young soccer players and compare them among different game positions.

Methods
The sample was composed of 54 Brazilian young soccer players. Tactical performance was measured by the System of Tactical Assessment in Soccer through the GR3-3GR test in 3770 tactical actions. Friedman followed by Wilcoxon tests were used to analyze differences between tactical principles. Subsequently, Kruskal Wallis and Mann Whitney U tests were performed to compare tactical efficiency between defenders, midfielders, and forwards (p < 0.05).

Results
Offensively, the results indicated that young players demonstrated less efficiency in executing the principle "depth mobility" compared to "penetration", "offensive coverage", "width and length", and "offensive unity". Regarding defensive aspects, "concentration" was performed more efficiently than other principles. Comparisons between positions indicated that midfielders and forwards executed "offensive unity" more efficiently than defenders. Defenders tended to present high "defensive coverage" efficiency when compared to "midfielders".

Conclusions
High efficiency in the execution of “concentration” represents an obstacle to vertilize a pass and hinders offensive movements between the last defender line and goal, given low efficiency of “depth mobility”. Midfielders and forwards performed "offensive unity" more efficiently than defenders. In defensive principles, defenders presented better performance in “defensive coverage”, giving support to the first defender. As practical applications, it is suggested that coaches of young regional soccer players carry out activities which allow depth passes to teammates as well as games to promote “offensive unity” for defenders and “defensive coverage” for midfielders.
