Differences in Gaze Behavior Between Male and Female Elite Handball Goalkeepers During Penalty Throws.

BACKGROUND

Recent research suggests that an athlete's gaze behavior plays a significant role in expert sport performance. However, there is a lack of studies investigating sex differences in gaze behavior during technical and tactical actions.

OBJECTIVES

Therefore, the purpose of this study was to analyze the eye movements of elite female and male handball goalkeepers during penalty throws.

METHODS

In total, 40 handball goalkeepers participated in the study (female: = 20; male: = 20). Eye movements were recorded during a series of five penalty throws in real-time conditions. The number of fixations and dwell time, including quiet eye, for selected areas of interest were recorded using a mobile eye-tracking system.

RESULTS

Significant differences were found in quiet-eye duration between effective and ineffective goalkeeper interventions (females: mean difference (MD) = 92.26; = 0.005; males: MD = 122.83; < 0.001). Significant differences in gaze behavior between female and male handball goalkeepers were observed, specifically in the number of fixations and fixation duration on the selected areas of interest (AOIs). Male goalkeepers primarily observed the throwing upper arm AOI, the throwing forearm (MD = 15.522; < 0.001), the throwing arm AOI (MD = 6.83; < 0.001), and the ball (MD = 7.459; z = 3.47; < 0.001), whereas female goalkeepers mainly observed the torso AOI (MD = 14.264; < 0.001) and the head AOI (MD = 11.91; < 0.001) of the throwing player.

CONCLUSIONS

The results suggest that female goalkeepers' gaze behavior is based on a relatively constant observation of body areas to recall task-specific information from memory, whilst male goalkeepers mainly observe moving objects in spatio-temporal areas. From a practical perspective, these results can be used to develop perceptual training programs tailored to athletes' sex.
