Brief Summary

Enhanced sports performance, in our current world, is being pushed at the professional level and down to school-age children as well. Money is being spent on lessons and equipment to enhance performance. One new method to enhance performance is stroboscopic vision goggles. The glasses lenses flicker removing visual information for a brief moment. The claim is that they train connections between the eyes, brain, and body. We want to see if this product truly does enhance visual performance during a softball season for high school girls.

Outcome Measures

Primary Outcomes (1)

• Vergence ranges

  Vergence ranges measured how many prism diopters the subject can turn their eyes in (base out) and how far they can relax them out (base in). This score is also a good measure of how much peripheral fusion a person has.

  8 weeks

Secondary Outcomes (7)

• Developmental eye movement

  8 weeks

• Randot stereopsis test

  8 weeks

• Accommodative ranges

  8 weeks

• Acuity

  8 weeks

• Stereo Scores

  8 weeks

Study Arms (2)

Stroboscopic Training Group

EXPERIMENTAL

Treatment group, which will receive stroboscopic training during hitting and fielding drills. The glasses look like sunglasses but have liquid crystal technology that causes a flicker from clear to opaque. The glasses flickering will be controlled on the side of the glasses by the researcher. When the athlete can complete a skill proficiently by catching or hitting during training the level of flickering will be increased to challenge the visual system more.

Device: Senaptec Strobe Glasses

Standard softball drills

ACTIVE COMPARATOR

Control group, which will perform normal hitting and fielding drills without stroboscopic training

Other: Standard softball drills

Interventions
