Abstract

Introduction: Athletes have differences in object tracking, search strategies, number and duration of fixations, dynamic visual acuity (DVA), and predictive eye movements than non-athletes (NON). However, these eye functions have not been assessed between athlete groups during a task that encompasses antisaccade and DVA characteristics. Purpose: To evaluate the oculomotor control sport paradigm differences between interceptive (INT) and strategic (STR) Division I collegiate athletes, as well as NON with an antisaccade task (AS) and a sport-like dual task (SDT). Methods: Fifty-seven participants (19 STR, 19 INT, and 19 NON) performed 2 trials of an AS and a SDT. Participants stood 55 in away from a monitor with a monocular eye tracker (240Hz) that used eye-to-head integrated to an 8 camera Vicon Motion Capture system (120Hz). Data were exported to MATLAB where a custom smoothing algorithm for AS and SDT resultant distance (RDA and RDSDT) and AS and SDT mean horizontal (MHVA and MHVSDT) velocity were applied. Four one-way ANOVAs measured the differences between groups. Results: There were no significant differences between INT and STR groups in RDA, RDSDT, MHVSDT. For the AS and SDT. The INT and STR had significantly greater RDA and RDSDT than NON (pDiscussion:RDA and RDSDT in both athlete groups were greater than the NON, while MHVA was lower than the NON. This could suggest that there are no saccadic differences between athlete groups, while the NON may be undershooting their eye movements during both tasks.
