Visual Perception Strategies of Foil Fencers Facing Right- Versus Left-Handed Opponents.

This study sought to determine differences in fencers' visual perceptions during duels (preparatory actions) with right- versus left-handed opponents. Participants were 12 top-ranking right-handed female foil fencers (aged 16-30 years, M = 20.86, SD = 4.76) taking part in a training camp. Testing employed SensoMotoric Instruments Eye Tracking Glasses (SMI ETG 2.0) with eye-tracking analyses covering the visual attention time devoted to various areas of the opposing fencer's body (areas of interest), average fixation, number of glances, and number of fixations during preparatory actions in duels. Each test was conducted during preparatory actions in 20-second staged duels, first against a right-handed, and then against a left-handed opponent. Against left-handed (vs. right-handed) opponents, fencers spent significantly more time looking at and significantly more often fixated on the armed hand. When fighting against right-handed (vs. left-handed) opponents, fencers devoted more time and fixated more often on the opponent's upper torso. These results may point to an interesting phenomenon in which left-handed fencers benefit from weaker strategies adopted by their right-handed opponents who may fixate on the forearm and arm of the weapon hand.
