Abstract

Topics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 3, 2025. This case study examined the effects of stroboscopic vision training during an entire varsity softball season for a 16-year-old female. Stroboscopic vision training uses specialized glasses with crystallized fluid that flickers, intermittently impeding vision, a technique that enhances visual performance. The stroboscopic glasses were worn two to three times a week during hitting and fielding skills. The central hypothesis was that the stroboscopic vision training would enhance softball vision performance. The central hypothesis was tested using these specific aims: 1) batting statistics for a year with no stroboscopic versus a year with the stroboscopic vision training; and 2) vision-specific measurements for tracking, peripheral vision, and eye teaming. For the first aim, coaches recorded on-base percentage, batting average, slugging percentage, and hard-hit ball percentage. The second aim was tested by an ophthalmologist in a vision therapy center, with developmental eye movement, vergence ranges, randot stereopsis, and accommodative ranges measured. The innovative application in this study was combining on-field performance and vision testing using stroboscopic goggles. Data from batting statistics demonstrated a 136% increase in batting average and a 168% increase in slugging percentage. Post-test vision measurements increased base in/eyes relaxed by two diopters. Vision measurements demonstrated improved overall reaction time and peripheral fusion (peripheral vision). Limitations are present in the results due to single-subject case study design; follow-up studies with larger sample sizes and control groups to validate these findings are needed. Future research with a more rigorous experimental design will build upon this case study.
