Effects of Stroboscopic Visual Training on Visual-Motor Performance in Elite Volleyball Players: A Case Study of EST Tajenanet

Abstract

Visual perception and visual-motor coordination are critical determinants of performance in volleyball, a sport characterized by rapid ball tracking, anticipation, and precise spatial awareness. Stroboscopic visual training, which involves intermittent visual occlusion during training, has emerged as an innovative method to enhance visual processing speed and motor response. However, empirical evidence on its effectiveness in elite volleyball remains limited, particularly in Algerian competitive contexts.
This study evaluated the effects of a stroboscopic visual training program on visual-motor performance parameters in elite male volleyball players from EST (Entente Sportive de Tajenanet), competing in the Algerian National Championship Division A.
A pre-post intervention design was implemented with 16 male volleyball players (mean age: 24.3 ± 3.2 years) from EST Tajenanet during the competitive season. The intervention consisted of a 12-week stroboscopic visual training program integrated into regular team training sessions (3 sessions per week, 45 minutes per session). Visual-motor performance was assessed through standardized tests including: visual reaction time, dynamic visual acuity, peripheral vision range, depth perception accuracy, and ball tracking precision. Paired-sample t-tests were used to assess pre-post changes, with significance set at p < 0.05.Significant improvements were observed across all visual-motor parameters. Visual reaction time decreased from 245.3 ms (SD = 28.4) to 218.7 ms (SD = 24.1), t(15) = 4.892, p < 0.001. Dynamic visual acuity improved from 0.82 (SD = 0.09) to 0.91 (SD = 0.07), t(15) = -5.234, p < 0.001. Peripheral vision range expanded from 168.4° (SD = 12.3) to 179.2° (SD = 10.8), t(15) = -3.876, p < 0.01. Depth perception accuracy increased from 78.3% (SD = 8.7) to 88.6% (SD = 6.4), t(15) = -5.012, p < 0.001. Ball tracking precision improved from 74.2% (SD = 9.1) to 86.5% (SD = 7.3), t(15) = -6.145, p < 0.001.
A structured stroboscopic visual training program can significantly enhance visual-motor performance in elite volleyball players. The results support the integration of sport vision training methodologies into volleyball training programs, particularly for teams competing at national championship level. The findings have practical implications for coaches seeking evidence-based approaches to improve anticipation, reaction speed, and overall visual performance in competitive volleyball.
