Through this study, we intend to evaluate whether the chromatic
variation in the equipment of the goalkeeper (GK) have interference on the
accuracy of soccer players when they shoot at goal. Our goal is to determine
the degree to which players can isolate visual stimuli related to the distraction
as a function of the polychrome outfit of the GK to make a shot on goal. In
this sense, we analyzed 40 players in the Portuguese national football league,
the trajectory of the ball cap on goal during a training situation, studying the
precision will change color depending on the GK. We used four different tests
to quantify the results, by which combine static and dynamic situations of the
attackers, along with a neutral colored dress and an alive color of the GK
clothes. The results show differences in the various tests.
