Eye Dominance-based Visual Training
Sponsor: Istinye University
Summary
Eye dominance refers to the preference for one eye when processing visual information and may influence visual-motor integration and motor coordination. In volleyball, where rapid decision-making, accurate target tracking, and precise hand-eye coordination are essential, visual processing plays a critical role in upper extremity performance. Although previous studies have investigated eye dominance and visual training in relation to motor control and athletic performance, evidence regarding their acute effects in volleyball players remains limited. This study aims to investigate the acute effects of eye dominance-based visual training on upper extremity motor performance in volleyball players. By evaluating a single-session, low-cost, and equipment-minimal visual training protocol, the study seeks to determine whether targeted visual exercises can produce measurable improvements in motor performance. The findings may contribute to the development of individualized visual-motor training strategies to support athletic performance and inform future research in sports science, physiotherapy, and motor control.

Interventions
Eye Dominance-Based Visual Training
Behavioral: Eye Dominance-Based Visual Training A single-session visual training protocol performed after the dominant eye is identified with the Miles test. It has five stations: (1) eye massage and palming for 30-60 seconds; (2) a letter saccade station, with fast shifts between letter charts, reading aloud and directional responses; (3) an anti-saccade station, with a response opposite to a colored cue, followed by receiving or passing a volleyball; (4) a Brock string station, with focusing on colored beads, followed by ball control or passing; (5) dynamic gaze stabilization, with fixation on colored targets while the eyes and the head/arm move in opposite directions. Each station is done for 3 sets of 10-15 repetitions, separately for the dominant and non-dominant eye. Arm: Eye Dominance Training Group
