Effective vs. missed penalties - Where do we look when we kick?

El deporte de alto rendimiento en la actualidad se caracteriza por el uso de la tecnología para el análisis de la técnica detrás de cada movimiento o gesto técnico. Por ejemplo, para los futbolistas profesionales el afinar la técnica para definir un gol, patear un tiro libre o penales no es solo cuestión de horas de práctica, sino también de revisar análisis estadísticos de sus jugadas. Pero, ¿cómo podemos analizar el comportamiento detrás de la forma más objetiva?

Durante la campaña al Mundial Rusia 2018, analizamos el movimiento ocular y puntos de mayor atención visual al momento de patear un penal con cuatro futbolistas profesionales: Gianmarco Gambetta de Alianza Lima, Rodrigo Cuba de Deportivo Municipal, Juan Diego Gutiérrez del Sport Boys y Carlos Olascuaga del Sport Rosario – con el objetivo de conocer diferencias entre cómo miran los jugadores antes de patear un penal efectivo y un penal fallido.

TECNOLOGÍA Y RESULTADOS

Using eye tracking technology, some interesting differences were found in these cases. EYE TRACKING(eye tracking) technology, some interesting differences were found in these cases. In successful penalty kicks, players looked more at the ball (46%) and the goalkeeper (34%) as opposed to those who missed, who focused more on looking mainly at the ball (76%), leaving aside attention on the goalkeeper and the goal area.

In addition, the analysis was deepened in the areas seen in the goal and some differences were also found. Players who did not score looked exclusively at the goalkeeper and then at the lower areas of the goal, while those who scored did look at all available areas.

Just as technology is complementing the work of referees to help them make more objective decisions, it is also facilitating the work of coaches by providing them with more information on the performance of their players and thus contributing to the improvement of their performance.
