The effect of fixation transitions on quiet eye duration and performance in the soccer penalty kick: instep versus inside kicks

Abstract  

Male goalkeepers of intermediate skill level attempted to stop penalty kicks executed with the instep and inside foot, in situ. A mobile eye tracker and an external camera were used to collect the gaze and motor behaviors of the goalkeepers, as well as the penalty takers' motor behaviors and flight of the ball. Percent saves was greater during instep (28%) than inside foot kicks (12%), but we detected few differences in fixation frequency, location, duration, or transitions that could be attributed to the type of kick used. Fixation transitions (or the frequency of gaze shifts between locations) were significantly higher on goals than on saves. During the final phase of the kicking action, the quiet eye was located on the visual pivot and was longer during saves than goals. Furthermore, when the final fixation on the ball exceeded approximately 1,100 ms, then the likelihood of goals increased. The results are discussed in light of past studies in goaltending and the dual demands of motor tasks that require information be fixated both early and late at spatial locations that exceed the limits of focal vision.
