Training effects on dynamic visual acuity (DVA) were determined over a range of target durations and target velocities under the viewing condition of free-head movement. Dynamic acuity levels were lower than static acuity levels, and training was found to be very effective in improving performance, particularly under the most difficult conditions in which performance was poorest. Improvement was also most evident among those observers who initially exhibited the poorest DVA scores. Preliminary comparisons between DVA scores of a nonselect sample of college students and those of a small group of college athletes indicated that the athletes were not very different from the nonselect group and would also benefit from training on the task.
在自由头部运动的观察条件下，测定了一系列目标持续时间和目标速度范围内训练对动态视敏度（DVA）的影响。动态视敏度水平低于静态视敏度水平，并且发现训练在提高表现方面非常有效，特别是在表现最差的最困难条件下。在最初DVA分数最差的观察者中，改善也最为明显。对一组非特定大学生样本和一小群大学生运动员的DVA分数进行的初步比较表明，运动员与非特定组没有太大差异，并且也将从该任务的训练中受益。
