运动员表现出更好的动态视力（DVA）相比，非运动员，而动作视频游戏玩家（VGP）的表现更类似于控制，尽管有类似的静态视力和屈光不正。组间DVA的差异与静态视力、屈光不正或平滑追踪增益的差异无关。目的：研究运动员和VGP的DVA是否上级对照组（非运动员，非运动员）。方法46名参与者（15名运动员，11名VGP，20名对照）年龄21.7岁（标准差，2.8岁）。受试者均为正视眼，两组之间单眼和双眼静态视力相同。使用速度为5、10、20和30°/s的可预测（水平）和不可预测（随机）运动目标评估动态视力。平滑追踪眼球运动进行了评估，使用水平运动步进斜坡刺激在相同的速度。本研究已在开放科学中心（https：//osf.io/eu7qc）进行了预注册。结果在30°/s时，组（F = 4.762，P = 0.01）和运动类型（F = 9.538，P = 0.004）的主效应显著。Tukey事后分析表明，运动员的表现优于对照组（t =-2.919，P < .02）。综合（组×运动类型×速度）重复测量ANOVA显示速度的主效应（F = 110.137，P < .001）和速度×运动类型的交互作用（F = 27.825，P < .001）。动态视敏度随速度的增加而降低，随机运动的变化斜率大于水平运动。两组之间的平滑追踪增益没有显著差异（P > 0.05）。结论：运动员在30°/s时的动态视力表现优于对照组。这种组间差异不能完全由平滑追踪眼球运动的差异来解释，因此可能反映了组间的其他差异。
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.
