The Effect of Sport-Specific Visual and Vestibular Training in Open-Skill Athletes

This study aims to examine the effects of a 6-week sport-specific visual and vestibular training program on athletes' reaction time and dynamic balance, while comparing outcomes with a control group to determine the extent to which the training contributes to performance improvements.

About this study

This pre-test and post-test experimental study will include 20 open-skill athletes randomly divided into two groups (n = 10 each): a control group and an intervention group.

The intervention group will participate in a 6-week sport-specific visual and vestibular training program conducted twice weekly, while the control group will continue their regular training and receive a one-time visual-vestibular educational brochure and online session. Reaction time and dynamic balance will be assessed at baseline and after the 6-week period. Reaction time will be measured using the Light Trainer system and dynamic/static balance will be evaluated using the ProKin 252 device.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Athletes aged 18-23 years.
  • Possess an active sports license in any open-skill sport (e.g., volleyball, basketball, football, etc.).
  • No upper or lower extremity injury or surgery in the past three months.
  • Participate in regular training sessions throughout the study period.

Exclusion criteria

  • Having an injury in the last three months that required being away from training for more than two weeks.

  • Having any neurological or cardiovascular condition.
  • Having any vestibular or visual disorder.

Treatment and study plan

Pinhole Glass Training

Other

Participants work in 5-person groups using pinhole glasses to restrict peripheral vision, performing a continuous 5-minute ball-passing exercise using both upper and lower extremities.The exercise is repeated three times over a period of six weeks

T-Drill Agility Exercise

Other

Participants complete a T-shaped course with BlazePod® lights, reacting to randomly illuminated cones and returning to the center; the exercise is repeated three times. The exercise is repeated three times over a period of six weeks

Letter Tracking Station

Other

Participants perform Eye Letter Saccades tasks by reading sequences of letters and numbers with eye movements while performing rapid lower limb stepping; a ball is caught at the 20th second, repeated three times. The exercise is repeated three times over a period of six weeks.

Sport-Specific Vestibulo-Ocular Reflex Training

Other

Participants fixate on a target while moving their head up and down and stepping rapidly; a ball is caught at the 20th second, repeated three times. The exercise is repeated three times over a period of six weeks
