NCT05956938

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.

Study Arms (3)

Action Video game Group

EXPERIMENTAL

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.

Device: Action Video Game

Stroboscopic Glasses Group

EXPERIMENTAL

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).

Device: Stroboscopic Glasses

Control Group

NO INTERVENTION

Participants in the control group will watch 1 video clip/series/film of 1 hour duration on a television located at least 1.5 meters away.
