Brief Summary

The aim of this pilot study was to investigate the effects of a stroboscopic training intervention on reactive agility and agility speed in basketball players, using identical movement patterns, and to evaluate perceptual-cognitive indices derived from the relationship between agility and reactive agility performance. This study hypothesized that stroboscopic visual training would significantly improve reactive agility and agility performance in adolescent male basketball players.

Outcome Measures

Primary Outcomes (2)

• Reactive agility

  Reactive agility performance was assessed using the Y-shaped agility test. The Y-shaped agility test was administered using a Witty photocell gate. The 45° angle between the midpoint of the trigger gate and the midpoints of the target gates was determined using a goniometer, and the photoelectric cells were positioned on the inner sides of the gates. Participants began the test 30 cm behind the start line and sprinted maximally through the first two gates. Immediately after completing the 5-m linear sprint by passing through the first two gates, a visual stimulus appeared on the computer screen positioned in front of the athletes. When the letter "A" was displayed, the athletes were instructed to sprint toward the cone labeled A, whereas when the letter "B" appeared, they were required to sprint toward the cone labeled B as quickly as possible. The fastest time obtained from the three trials was used for the statistical analysis.

• Agility

  Agility performance was also assessed using the Y-shaped agility test. Prior to each trial, the athletes were informed of the direction of the turn. They were instructed to perform the change-of-direction task, which involved an approximately 45° directional change, as quickly as possible. In addition, athletes were instructed not to initiate the change of direction before passing through the trigger gate. Three trials were completed for each direction (left and right), and the fastest trial for each direction was included in the analysis.

Study Arms (2)

Stroboscopic visual training group (SVT)

EXPERIMENTAL

The SVT group performed basketball-specific neuromuscular warm-up exercises combined with stroboscopic glasses (Senaptec Strobe, Beaverton, ABD) at a duty cycle of 100 ms clear/150 ms opaque twice per week. Specifically, stroboscopic eyewear alternates between transparent and opaque phases at adjustable frequencies, thereby restricting the amount and continuity of visual information available to the athlete. This controlled visual disruption is thought to activate neural networks involved in visual and cognitive processing, compelling athletes to perceive, decide, and respond under conditions of reduced or intermittent visual input.

Other: Neuromuscular exercise training with stroboscopic glassess

Control group

OTHER

Control group completed the identical neuromuscular warm-up exercise protocol under normal visual conditions without visual perturbation.

Other: Control group
