Abstract：
The purpose of this study was to investigate the difference in oculomotor functioning between Olympic-level contact and non-contact sports participants. In total, 67 male and female Olympic-level contact (n = 27) and non-contact (n = 40) athletes completed oculomotor tasks, including Horizontal Saccade (HS), Circular Smooth Pursuit (CSP), Horizontal Smooth Pursuit (HSP), and Vertical Smooth Pursuit (VSP) using a remote eye tracker. No significant differences for sex or age occurred. Each variable indicated higher scores for contact compared to non-contact athletes (p < .05) except for VSP Pathway differences and CSP Synchronization. A logistic regression was performed to determine the degree that HS measures, CSP synchronization, and VSP pathway predicted sport type. The model was significant, χ2(6) = 37.08, p < .001, explaining 57.4% of the variance and correctly classified 88.1% of cases. The sensitivity was 87.5% and specificity was 88.9%. CSP synchronization did not increase the likelihood of participating in a contact sport. This was the first study to identify oculomotor differences between Olympic athletes of contact and non-contact sports, which adds to the growing evidence that oculomotor functioning may be a reliable, quick, real-time tool to help detect mTBI in sport.
摘要：
这项研究的目的是调查奥运水平接触和非接触运动参与者的动眼功能差异。总的来说,67名男女奥林匹克级接触（n=27）和非接触（n=40）运动员完成了动眼任务，包括水平扫视（HS），圆形平滑追踪（CSP），水平平滑追踪(HSP),和使用远程眼睛跟踪器的垂直平滑追踪(VSP)。性别或年龄没有显着差异。除VSP路径差异和CSP同步外，每个变量均显示与非接触运动员的接触得分更高（p<.05）。进行逻辑回归以确定HS测量的程度，CSP同步,VSP通路预测运动类型。该模型意义重大，χ2（6）=37.08，p<.001，解释了57.4％的差异，正确分类了88.1％的病例。敏感性为87.5%，特异性为88.9%。CSP同步并没有增加参加接触运动的可能性。这是第一项研究，以确定接触和非接触运动的奥运运动员之间的动眼差异，这增加了越来越多的证据表明动眼功能可能是可靠的，快,实时工具，以帮助检测运动中的mTBI。
