The present study examines the visual behavior of young volleyball players during block action. The aim was to analyze visual search behaviour and the main locations during the action, establishing relationships between them and the percentage of correct answers.29 female volleyball players (17,4 ± 0,9 years old) should decide the direction of the setting while the viewed video sequences projected in actual size. The players registered their decision through their movement, which was recorded by a video camera at 25 fps and analyzed frame by frame. Visual behavior of the players is obtained through a system of eye tracking (ASL Mobile Eye), and analyzed according to the two different ball destinations: Zone 3 and Zone 4. Pearson correlation coefficient was calculated between the percentage of total hits and the different variables of visual behavior, and inferential statistics were applied to test for differences depending on the area. Players were more attuned to the information on the ball with that contained in the setter, and this is the source of information on which they based their decisions primarily. Fixing the ball-wrist area in early contact times may be the key to a correct anticipation in this action, as it would allow extracting information of the ball and the arm of the setter while using peripheral vision.
