This study investigated whether the eight standard tests of sports vision used in Japan appropriately reflect sports vision; whether all eight tests are necessary; and if not, which combination yields the optimal model. Participants were kendo practitioners (exercise group, n = 41) and those with no exercise habits (non-exercise group, n = 65). The performance of the two groups on all eight tests were compared. The groups differed in static visual acuity, kinetic visual acuity, and eye/hand coordination. A high correlation (r = 0.75) was observed between static visual acuity and kinetic visual acuity, while contrast sensitivity was moderately correlated with static visual acuity and kinetic visual acuity (r = 0.6), and dynamic visual acuity was moderately correlated with eye/hand coordination (r = - 0.66). Logistic regression analysis indicated that it is not necessary to conduct all eight tests; the optimal model included static visual acuity, visual reaction time, and eye/hand coordination. Our results suggest that static visual acuity, visual reaction time, and eye/hand coordination are sufficient for assessing visual function in kendo practitioners. For other sports, it may be possible to construct discriminative models using the same method and determine which aspects of visual function and which training methods to emphasise in a given sport.
本研究旨在探讨日本常用的八项运动视觉标准测试是否能准确反映运动视觉，是否所有八项测试都是必要的，如果不是，那么哪种组合能得出最佳模型。参与者包括剑道练习者（运动组，n=41）和无运动习惯者（非运动组，n=65）。比较了两组在八项测试中的表现。两组在静态视力、动态视力和手眼协调方面存在差异。静态视力和动态视力之间存在高度相关性（r=0.75），而对比敏感度与静态视力和动态视力中度相关（r=0.6），动态视力与手眼协调中度相关（r=−0.66）。逻辑回归分析表明，并非所有八项测试都是必要的；最佳模型包括静态视力、视觉反应时间和手眼协调。本研究结果表明，静态视力、视觉反应时间和手眼协调足以评估剑道练习者的视觉功能。对于其他运动项目，可能可以使用相同的方法构建具有区分度的模型，并确定在特定运动项目中需要强调哪些视觉功能和哪些训练方法。
