Defence: Visual Perception in Elite Football

November 3, 2021, Karl Marius Aksum defends his doctoral dissertation «Visual perception in elite football» at the Norwegian School of Sports Sciences (NIH).



November 3


NIH - Auditorium Innsikt




The present thesis provides new research about the frequency, timing, duration, and information of scanning in elite football players.

It also provides results from the first-ever study of gaze behavior of elite football players in 11 v 11 match play.

Overall, the findings suggest that future research on visual perception in football should strive to develop more representative designs in non-restrictive settings. Furthermore, coaches should aim to develop football players’ skills with the help of complex contextualized exercises that include an abundance of information, as opposed to decontextualized and isolated exercises in which vital information is removed from the players.
