Abstract
The present study aimed to verify the influence of the Relative Age Effect over the tactical performance of U-13 youth soccer players. The sample was comprised by 56 U-13 youth soccer players. The players were grouped in trimester (T1-Jan/Mar, T2-Apr/Jun, T3-Jul/Sep and T4-Oct/Dec). The instrument used to assess players' tactical performance was FUT-SAT. Significant differences were found between birth trimester for the tactical principles "Delay" and "Concentration". However, none of the results indicated better performance of the players who were born within the first trimester. It is concluded that the Relative Age Effect did not influence the tactical performance of U-13 youth soccer players.
