ResumoThe saccadic eye movement provides the focus of a visual object of interest to the retina. In sports like volleyball, identifying relevant targets as quickly as possible is essential to a skillful performance. The training improves cortical regions underlying saccadic action, enabling more automated processing in athletes. We investigated changes in the latency during the saccadic eye movement and the absolute theta power on the frontal and prefrontal cortex during the execution of the saccade eye movement task in athletes and non-volleyball athletes. We hypothesized that the saccade latency and theta power would be lower in athletes as a result of training and the perceptual-cognitive enhancement in volleyball players. Thirty healthy volunteers were recruited for this study: 15 volleyball athletes (11 men and 4 women, mean age: 15.08 ± 1.06) and 15 non-athletes (5 men and 10 women, mean age: 18.00 ± 1.46). All tasks were performed simultaneously with electroencephalography signal recording. The result of the saccade latency of the saccadic eye movement presented a significant difference between the groups, a shorter time was observed among the athletes, associated with the superiority of the players in the attention level. Our results of saccade latency and the absolute theta power evidenced the specificity of the group the athletes. A decrease in absolute theta power was observed in the athletes compared to non-athletes on the electrodes of each frontal and prefrontal area during the experiment.
