The Quiet Eye (QE) variable measures the duration and location of the last visual fixation before initiating the critical part of movement of a motor task. Studies have shown that QE with longer durations and placed in an important location to the task, indicate better performance of elite players when compared to unskilled. This statement is also true for the free throw of basketball. However, so far it is not known regarding the measurement of this variable in situations relative to the behavior of unskilled players during hit free throw and misses on free throw. The aim of this study was to determine the duration and location of QE in hits and misses free throws from unskilled players. Eight young adults (22.71±1.97 years) with low level of basketball in free throws participated in the study. The gaze behavior during free throw was acquired using the Eye Tracker (ASL, model H6), with a frequency of 60 Hz data acquisition and the movement phases were determined by the video of the movements record by an external camera, being positioned laterally in a sagittal view. The movement phases were: preparation, extension 1, flexion and extension 2, the critical phase for this particular task and QE measurement was at the 'extension 2' of the elbow. For QE analysis, Quiet Eye Solutions software was used to identify the location and duration of QE. Anova one-way with repeated measures were performed with accuracy (hit, miss), with an alpha value of 0.05. The results showed that for the duration mean of the QE there was not significant difference (p = 0.458) between hits throws (898 ± 437ms) and missed throws (808 ± 338ms). The areas determined in the scene to distinguish the fixation locations indicated that during the hits, the location of the QE occurred 30% of the time in the center of the hoop...
