Abstract
This study aimed to compare gaze behavior—focusing on quiet eye (QE) and anticipation—between expert and non-expert female team handball goalkeepers during 7-meter penalty throws. Six goalkeepers (four elite, two non-elite) from the same Danish Division 1 club took part. Under standardized laboratory conditions, gaze was recorded with a head-mounted monocular eye tracker while concurrent 3D motion capture documented kinematics. The results showed no significant group differences in QE duration, QE onset, or QE offset. Eye tracking indicated that both groups primarily fixated on the thrower’s arm and the trunk/hip region. Differences in anticipation or save outcomes are not reported in the excerpt. In this small sample, the findings do not support the hypothesis of longer QE or clearer anticipatory advantages in experts, and further research is warranted given prior evidence that QE can be a key marker of expertise in other sports.
Formålet med dette studie var at sammenligne blikadfærd – med fokus på quiet eye (QE) og anticipering – mellem ekspert- og ikke-ekspertkvindelige håndboldmålmænd under 7-meter straffekast. Seks målmænd (fire elite og to ikke-elite) fra samme danske 1. divisionsklub deltog. Under standardiserede laboratorieforhold blev øjenbevægelser registreret med et hovedmonteret, monokulært eye-tracking-system, og bevægelsesdata blev samtidig indsamlet med 3D-bevægelsesanalyse. Resultaterne viste ingen signifikante forskelle mellem grupperne i QE-varighed, QE-onset eller QE-offset. Begge grupper rettede primært blikket mod kasterens arm samt krops- og hofteregionen. Data om forskelle i anticipering eller redningsprocent fremgår ikke af uddraget. I denne lille stikprøve understøtter resultaterne ikke hypotesen om længere QE eller tydeligere anticipationsfordel hos eksperter, og der peges på behov for yderligere forskning, da tidligere studier i andre sportsgrene indikerer en central rolle for QE i ekspertiseudvikling.
