How modifications in goals in small-sided and conditioned games in soccer influence the tactical actions of young soccer players

Abstract

Purpose. This study analysed the influence of the absence of goalkeeper and the number of goals in tactical actions in 3 configurations of small-sided and conditioned games (SSCGs): (a) goalkeeper + 3 vs. 3 + goalkeeper; (b) 3 vs. 3 (no goalkeeper); and (c) 3 vs. 3 with 2 mini goals. Methods. Overall, 24 under-15 soccer players were divided into 8 teams of 3 players each. Seven games were played for each configuration for a total of 21. The tactical behaviour was evaluated with the System of Tactical Assessment in Soccer (FUT-SAT). Results. More offensive actions were performed in the SSCGs with goalkeepers. The games played without goalkeepers led to more actions associated with defensive unity but also a higher rate of errors concerning the tactical principles of delay and defensive unity. In relation to the outcome of actions, more fouls, throw-ins, and corner kicks were observed in the SSCGs with 2 mini goals. Conclusions. The games played without goalkeepers reflected a higher difficulty in managing spaces of the game and led to a higher number of errors in the performance of core defensive tactical principles. In the games played with 2 mini goals, it was observed that the players on the wings were positioned closer to each other, which made the play more fragmented compared with the other conditions. In accordance with these results, it is possible to identify the influence of goalkeepers on tactical behaviour during SSCGs.
