A influência do constrangimento da tarefa no comportamento da procura visual em futebolistas

Abstract

Over time, football has been an area of study in many ways. More recently, researchers have devoted special attention to the study of human perception and cognition, specifically the players gaze behaviour, which has been recognized as a relevant factor for sports performance. Thus, the aim of this study was to compare the gaze behavior of defensive football players according to the tasks in small-sided and conditioned games (1vs.1 + GR and 2vs.1 + GR). The sample consisted of six university football players (28,5±3,39 years old) evaluated. The field tests consisted of two Small-Sided Games accomplishment in tasks of 1vs.1 + GR and 2vs.1 + GR. The gaze behaviors were captured and analyzed by Tobii Pro Glasses 2 eye movement recording system. It was used taking into account the categories: Number of Fixations by Area of Interest (Ball, Hip, Leg With Ball, Leg Without Ball, Space Game, Space in front of the ball, Space Player and Trunk) and Duration of Fixation by Area of Interest. The results showed that Space Game showed a strong and significant correlation between the execution tasks [NF (p= .007)]. It means that the defending players fixed more on this Area of Interest, when they were on a 2vs.1+GR than in a 1vs.1+GR task. Players showed also a tendency to fix the Space Game in 2vs.1+GR more than 1vs.1+GR task [DF (p= .094)]. When considering the Ball, there was a tendency for this area to be less fixed [NF (p= .050)] and for less time [DF (p= .082)] by deffenders as the number of opposing players were added to the task. We concluded that defending players fix / tend to fix more in the Space Game in 2vs.1+GR task while in 1vs.1+GR tasks they tend to fix more to the ball.
