No specific disease or clinical condition is being studied. This study investigates sports visual ability, visuomotor reaction performance, and soccer-specific performance in healthy collegiate soccer players. Other
Conditions
Interventions
Participants will be randomly allocated to either the stroboscopic visual training group or the non-stroboscopic control group in a 1:1 ratio.
Both groups will complete the same 6-week soccer-specifi

Exclusion criteria
Exclusion criteria: 1. History of epilepsy, photosensitive epilepsy, or seizures induced by flickering visual stimuli 2. History of migraine, severe dizziness, vestibular disorder, or marked discomfort during visual flicker exposure 3. Current lower-limb musculoskeletal injury or pain that may affect soccer training, running, change-of-direction performance, or testing 4. Neurological, cardiovascular, or other medical conditions that may affect safe participation in high-intensity soccer-specific training or visuomotor testing 5. Uncorrected visual impairment, clinically diagnosed eye disease, or visual problems that prevent completion of sports vision assessments 6. Participation in other structured visual training, stroboscopic training, or similar perceptual-cognitive training during the study period 7.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Visuomotor reaction performance measured using the Senaptec Sensory Station and related reaction tasks. The main measures include simple motor time and complex reaction speed. Lower-limb simple reaction time will also be assessed using a lower-limb reaction task requiring participants to respond rapidly to external visual stimuli at Baseline before the intervention and immediately after the 6-week intervention;Soccer-specific reactive agility performance measured using Fitlight-based reactive agility tests. The main measures include with-ball reactive agility time and without-ball reactive agility time. Participants will respond to randomly presented visual light stimuli and complete direction selection, movement initiation, change-of-direction actions, and ball-control or non-ball movement tasks as required. Completion time will be recorded in seconds, with shorter times indicating better performance at Baseline before the intervention and immediately after the 6-week intervention | — |
Secondary
| Measure | Time frame |
|---|---|
| Sports visual ability measured using the Senaptec Sensory Station. Measures may include reaction time, eye-hand coordination, depth perception, near-far quickness, perception span, multiple object tracking, dynamic visual acuity, visual clarity, contrast sensitivity, or other available sports vision indicators generated by the Senaptec assessment system at Baseline before the intervention and immediately after the 6-week intervention | — |
