Summary

This observational case series examined the barrier-step action in elite futsal goalkeepers. The aim was to describe how this goalkeeper-specific defensive movement was organised in time and how selected body angles were configured during execution. Three male professional futsal goalkeepers with international experience each performed three valid dominant-side trials under standardised indoor conditions. The task involved responding to a standardised low ball stimulus delivered by the coach from the penalty mark at a distance of 5 m.

Video data were recorded using a GoPro Hero 10 camera operating at 240 frames per second and analysed frame by frame in Kinovea. The movement was segmented into three operational intervals: initiation-propulsion, lateral transfer, and terminal support-stabilisation. Projected shoulder, hip, knee, and ankle angles were extracted at two analytically defined instants: the end of Interval 1 and the blocking configuration reached during Interval 2. Descriptive statistics were used to characterise between-goalkeeper variation and within-goalkeeper consistency in the barrier-step action.

Standardised barrier-step assessment task

Participants performed the barrier-step action in response to a standardised low ball stimulus delivered by the coach from the penalty mark at a distance of 5 m. Each participant completed three valid dominant-side trials under standardised indoor conditions, and the movement was analysed using single-camera two-dimensional video.
