A comparison study of dynamic visual acuity (DVA) was conducted using samples of nonathletic college students and college baseball players. The experimental population consisted of 17 male baseball players ranging in age from 19-24 years. The control population was made up of 25 male graduate students ranging in age from 23-29 years. Subjects reported the direction of a 20/25 "Landolt C" target exhibiting uniform angular motion produced by a projection system. Angular target velocities between 10 deg/sec and 110 deg/sec with an exposure time of 400 ms were used. The results showed a statistically significant difference between the two groups' DVA. The mean DVA for the baseball players was 82.35 deg/sec and 69.90 deg/sec for the control group.
使用非体育专业大学生和大学棒球运动员样本进行了动态视力（DVA）的比较研究。实验人群包括17名年龄在19至24岁之间的男性棒球运动员。对照人群由25名年龄在23至29岁之间的男性研究生组成。受试者报告由投影系统产生的以均匀角运动呈现的20/25“兰多尔特C”目标的方向。使用了10度/秒至110度/秒的角目标速度，曝光时间为400毫秒。结果显示两组的动态视力存在统计学上的显著差异。棒球运动员的平均动态视力为82.35度/秒，对照组为69.90度/秒。
