Brief Summary

The study aims to observe the possible improvement of performance in dynamic visual acuity (DVA), in terms of speed and trajectory, comparing training using action video games and strobe glasses. The results will allow us to understand which visual training is more beneficial for improving dynamic visual acuity in athletes.

Detailed Description

During the last years there have been several investigations related to the effect of action video games (VA) on the visual system, specifically perceptual and cognitive processes. These investigations indicate that playing VA can be a powerful tool for improving visuo-spatial attention, visuo-motor control, and reaction time. On the other hand, certain studies indicate that the use of stroboscopic glasses can help improve sports performance, and especially dynamic visual acuity , as well as various visual performance skills. The study aims to observe the possible improvement of performance in dynamic visual acuity (DVA), in terms of speed and trajectory, comparing training using action video games and strobe glasses. The results will allow us to understand which visual training is more beneficial for improving dynamic visual acuity in athletes.

Arm && Interventions

Group	Intervention	Description
Action Video game Group	Action Video Game	A one-hour training session will be held, divided into 2 30-minute sessions over 2 days. Each session will take into account an increase in the difficulty of the task gradually based on the nature of the video game. The video game selected will be ContraIII: Alien Wars, from the Nintendo Mini Classic console.
Stroboscopic Glasses Group	Stroboscopic Glasses	A one-hour training session will be held, divided into 2 30-minute sessions over 2 days. Each session will take into account a gradual increase in the difficulty of the task, divided into three visuomotor and anticipation components (ball size, type of trajectory and distance from the stimulus). The training sessions will consist of 2 series, and will be based on passing a ball between two people. Every 60 passes the flicker level of the glasses will increase, starting with level 1 (6hz) and ending at level 6 (1.75hz).
