Oculomotor Control in Amputee Soccer Players

Abstract

The authors investigated the dynamics of saccadic parameters during a stationary oculomotor target task in amputee soccer players (n = 16), able-bodied soccer players (n = 16), and nonathletic control subjects (n = 16). Eye movements during the visual-search tasks were recorded binocularly using a mobile eye-tracking system, and the gaze parameters were analyzed (fixation duration, saccade duration, saccade amplitude, saccade average acceleration, saccade peak deceleration, saccade average velocity, and ocular mobility index). The average saccade acceleration in the amputee soccer players was significantly lower than in the able-bodied players (p = .021). Other saccade characteristics in disabled athletes were comparable to those of the able-bodied groups. Moreover, the able-bodied soccer players presented faster saccadic parameters than nonathletes in terms of saccade acceleration (p = .002), deceleration (p = .015), and velocity (p = .009). The modification of oculomotor functions may result from extensive practice and participation in ball games. The authors’ hypothesis that oculomotor functions in amputee soccer players may be impaired was not fully confirmed.

A review of the essential visual skills required for soccer: Beyond 20–20 optometry

“…Soccer players must be able to monitor the ball with their eyes, which requires quick, accurate saccades (or eye movements) in order to keep up with the 21 other players and the ball on the pitch ( 39 ). Visualizing the relevant information as rapidly as feasible is crucial for making successful timely motion reactions to prior actions or judgments ( 44 ). In soccer, since the emphasis alternates between nearby and distant objects, eye tracking is crucial.…”
