Relationships between gaze behaviour and fencing performance of high-skilled fencing athletes: Perspectives from defensive and offensive phases

This study explores the relationship between visual processing and fencing performance, focusing on various gaze behaviour indices in a dynamic and interactive sport. Visual processing, particularly the ability to gather and use visual information quickly and accurately, is critical for performance in high-speed sports. We hypothesised that visual behaviour, including the duration of the final fixation (Quiet Eye; QE), the number of fixations and the number of scanned locations, significantly impacts fencing performance during offensive and defensive actions. National-level sabre fencers performed a 10-min assault with eye-tracking technology measuring their gaze behaviour. Results indicated that QE was significantly longer before successful touches compared to unsuccessful ones (Bayes factor (B) = 30.92). Additionally, the number of fixations and the number of scanned locations were higher during defensive actions than offensive actions (all Bs ≥ 1908.99). This research provides insights into the cognitive processes underlying sports performance in a realistic context and has implications for training strategies, emphasising the importance of various visual behaviour patterns in fencing.
