This study investigated the influence of spatio-temporal variables of interpersonal coordination on players' decision-making within the penalty area of the soccer. We analyzed shooting events (n= 71), passing (n= 26) y dribbling (n= 30), which was choose from 12 games of an amateur Colombian championship and analysed using TACTO software. The spatiotemporal variables were: (i) shooting angle: formed by vectors liking the ball carrier (vertex) to two opponents that generated a gap in the goal; (ii) passing angle A: vectors connecting the ball carrier (vertex) to his nearest defender and to a teammate; (iii) passing angle B: vectors linking the ball carrier (vertex) to a teammate and to the teammate's nearest defender; (iv) interpersonal distance: between the ball carrier and his nearest defender; v) velocity: change rate of each of the measures, depending on the duration of the play; vi) variability: coefficient of variation of each of the measures from the beginning to the end of the play. The results revealed that, values of the shooting angle were higher when players decide for shooting, comparing to situations in which the players decided to pass or dribble; and, the interpersonal distance was shorter in dribbling situations, comparing to passing situations. It was concluded that, the shooting angle and the interpersonal distance, functioned as control parameters in shooting at goal and dribbling situations, respectively.
