Purpose. The aim of this study was to examine the relationship between impulsiveness and tactical performance of U-15 youth soccer players.

Methods. The sample comprised 100 U-15 youth soccer players. Impulsiveness and tactical performance were assessed using the Continuous Performance Test-II (CPT-II) and the System of Tactical Assessment in Soccer (FUT-SAT), respectively. FUT-SAT enables evaluation of ten core tactical principles of soccer game: (i) penetration; (ii) offensive coverage; (iii) depth mobility; (iv) width and length; (v) offensive unity; (vi) delay; (vii) defensive coverage; (viii) balance; (ix) concentration; and (x) defensive unity. Impulsiveness values were obtained using the Omission and Commission Error analysis. Tactical performance values were obtained through the Game Tactical Performance Index (GTPI), Offensive Tactical Performance Index (OTPI) and Defensive Tactical Performance Index (DTPI). The Kolmogorov–Smirnov test and Spearman’s Correlation one were performed (p < 0.05) through SPSS, v. 22.

Results. We observed a positive correlation between impulsiveness and GTPI (rho = 0.226; p = 0.018).

Conclusions. It is concluded that impulsiveness is related to tactical performance of U-15 youth soccer players.
