Perceção e ação no futebol: Desempenho Decisional em Futebolistas sob Diferentes Intensidades de Esforço em Jogos Reduzidos e Condicionados

Abstract

The aim of this study was to compare defensive tactical behavior and the visual search behavior according to different levels of perceived effort in small-sided and conditioned games (SSCG). Ten universities (24.25±2.51yrs) were evaluated. The field tests consisted of 2 vs 1+GK SCCG. Players´ tactical behavior was assessed based on core tactical principles of soccer. Visual search data was recorded using a Tobii Pro Glasses 2 eye-movement registration system in which the following categories were defined; the fixation duration per locations and number of fixations per locations, such as ball, space, spaceplayer, playerball and undefined. The participants were separated in two groups, high intensity group and low intensity group according their perceived exertion. There were no significant differences in defensive tactical performance and number of fixations per location. A statistical significant decreased was found in fixation duration in space of the player in ball possession between first and second moment in high intensity group (t(1)= -3.47, p= .04). In conclusion, the players with higher level of perceived exertion concentrate their foveal vision on "spaceplayer" to reach the same performance than the other players
