Abstract:
Background/Objectives: The study had two objectives: first, to assess the intra- and inter-day reliability of a novel eye tracking device (EyeGuide Focus) in healthy adults; and second, to explore its applicability in measuring fatigue associated with physical strain, pre- and post-rugby match. These objectives were investigated in a two-part study. Methods: For Part A, 20 healthy participants (Mage ± SD = 30 ± 7 years) completed morning and afternoon testing with the EyeGuide Focus over two consecutive days (Day 1 and Day 2) and one day a week later (Day 8). For Part B, 12 female participants (Mage ± SD = 25 ± 5 years) completed EyeGuide Focus measurements pre- and post-rugby union match. Results: The results indicate moderate-to-high intra-day and inter-day reliability (ICCs 0.58-0.79). Fatigue induced by a rugby union match did not significantly alter EyeGuide Focus scores (p > 0.05), suggesting stability in measurements despite physical exertion. Conclusions: The sensitivity of the EyeGuide Focus to minor variations in fatigue warrants further investigation as a tool to aid monitoring and performance.
