[Thésaurus Mesh]Vision oculaireRésumé : SIGNIFICANCE: Athletes exhibit better dynamic visual acuity (DVA) compared with nonathletes, whereas action
video game players (VGPs) perform more similarly to controls despite having similar static visual acuity and refractive errors. The differences in DVA between groups were not related to differences in static visual acuity, refractive
error, or smooth pursuit gain.
PURPOSE: The purpose of the study was to examine whether athletes and VGPs have superior DVA than controls
(nonathletes, nongamers).
METHODS: Forty-six participants (15 athletes, 11 VGPs, 20 controls) aged 21.7 years (standard deviation,
2.8 years) were recruited. Participants were emmetropic with equivalent monocular and binocular static visual
acuity between groups. Dynamic visual acuity was assessed using predictable (horizontal) and unpredictable (random) motion targets at velocities of 5, 10, 20, and 30°/s. Smooth pursuit eye movements were assessed using a
horizontal motion step-ramp stimulus at the same speeds. This study was pre-registered with the Center for Open
Science (https://osf.io/eu7qc).
RESULTS: At 30°/s, there were significant main effects of group (F = 4.762, P = .01) and motion type (F = 9.538,
P = .004). Tukey post hoc analysis for groups indicated that athletes performed better than did the control group
(t = −2.919, P < .02). An omnibus (group motion type speed) repeated measures ANOVA showed a main effect of speed (F = 110.137, P < .001) and a speed motion-type interaction (F = 27.825, P < .001). Dynamic
visual acuity decreased as speed increased, and the slope of the change was greater for random than for horizontal
motion. Smooth pursuit gains were not significantly different between groups (P > .05).
CONCLUSIONS: Athletes have superior dynamic visual acuity performance compared with controls at 30°/s. This
between-group difference cannot be fully explained by differences in smooth pursuit eye movements and therefore
may reflect other differences between the groups.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Vision oculaireMots-clés : œil silencieux coordination visuo-motrice Résumé : SIGNIFICANCE: The quiet eye is a gaze behavior that seems to differentiate both expert-novice performance and successful and unsuccessful performance in experts; however, the quiet eye may only represent one aspect of the perceptual-cognitive expertise differences that exist between athletes and nonathletes. Research suggests that expert-novice differences in vision and visual-motor coordination skills exist between athletes and nonathletes, although the underlying mechanisms driving these differences are not well understood. The quiet eye is the final fixation or tracking gaze made before the initiation of the action of importance in a motor coordination task and is quite possibly the most well-studied vision strategy variable in sport. The quiet eye has been shown to be a key component of both expert ability and successful performance. However, the quiet eye is not without its criticisms, and the perceptual mechanisms underlying this unique gaze behavior are not yet well understood. The question that remains to be answered is whether the differences in vision and visual-motor coordination skills that exist between athletes and nonathletes can be explained by the quiet eye alone or if the explanation is more complicated Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
