Athletic Performance Introduction: The purpose of this study was a comparison of environmental constraints changes on quiet eye factors during performance skill of throw targeting between various athletes with three different levels of skill. Materials and Methods: Thirty athletes (22-28 years) were selected in three levels; elite, expert, and novice. The interaction of regulatory conditions (stationary/in motion) and intertrial variability (present/absent) created four target conditions and recorded characteristics related to gaze behavior continuously in any scenario. Using an eye-tracking device, gaze behavior was recorded and analyzed by an information processing system. Results: Athletes at the elite level had significantly quiet eye onset and longer quiet eye periods compared to athletes with semi-skilled and beginner levels. Conclusion: The results of the present study emphasized the importance of quiet eye characters on the successful performance of athletes with earlier onset and longer duration of the quiet eye, particularly when presented assignment-related information in different shapes and regions in the wide field of vision.n ABSTRACT Article Info:
