Resumo:This thesis aimed to investigate informational variables that constrain the dynamics of interpersonal coordination underlying players’ decision-making behaviour in team sports. We begin with a position paper highlighting the need for understanding how performers interact and generate goal-directed adaptive behaviours coupled to the information sources unfolding in the performance contexts. Thereafter, in all empirical studies performer-environment interactions are analysed with process-tracing methods to examine behaviours’ dynamics. Relevant variables expressing players’ behavioural interactions were identified and analysed in matches and rugby sub-phases (i.e., 1vs1, 1vs2, 3vs3). Analysis of the distance gained dynamics in attacking phases of actual matches revealed that ball displacement provides information on team successful performance. Besides, this variable dynamics described the functional coordination between players and teams. Using also actual match data, the functional role of gap closing information during 1vs1 sub-phases was analysed. Time-to-contact between attacker and defender was suggested as yielding information about future pass possibilities. In an in situ simulation of 1vs2 sub-phase, the manipulation of the initial distance between defenders demonstrated that decision-making behaviours are differently expressed as a function of changes made in participants’ spatial location. This gave evidence for the flexible and adaptive nature of players’ goal-directed behaviour to current task constraints. Finally, observations of participants performing a virtual reality simulation of 3vs3 sub-phase revealed how opening of gaps in the defensive line shapes decision-making behaviour of the ball-carrier. An expertise effect was demonstrated for perceiving and acting upon affordances. In conclusion, this body of research found that decision-making behaviour emerges sustained by specific spatial-temporal information from goal-directed interactions between players.
