The effects of sports visual training on sports performance and visual functions in partially sighted people

本研究旨在阐明部分视障者的运动视觉特征，以及运动视觉训练对部分视障者运动表现和视觉功能的影响。弱视人群动态视力（DVA）和眼手协调能力（E/H）均低于正常人，且个体差异较大。受试者的视野受限状况影响结果。严重视野问题但视力损失较小的被试表现相对于视力损失但视野正常的被试表现较差。有球类运动经验的受试者比没有球类运动经验的受试者获得了更好的结果。弱视者接受运动视觉训练，包括DVA、E/H和运动表现训练，每周两次，持续两个月。训练前后分别进行运动视力测试和运动表现测试。训练结束后，训练对运动视力的影响不显著。在性能测试中有轻微的训练效果。在视觉训练之后，弱视的人报告说，他们觉得自己比以前更能识别周围的环境。提示运动视觉训练对弱视人群的视觉功能有一定的改善作用。

The purposes of this research were to clarify the features of sports vision in partially sighted people and the effects of sports visual training on sports performance and visual functions in partially sighted people. The results of dynamic visual acuity (DVA) and eye/hand coordination (E/H) of partially sighted people were lower than those of sighted people and the individual varieties were great. The status of visual field restriction in the subjects affected the results. The subjects with severe visual field problems, but with little visual acuity loss, showed relatively lower performance than those with visual acuity loss but with normal visual field. The subjects who had experience playing ball games gained the better results than the people who did not have any ball game sports experience. The partially sighted people received sports visual training which includes the DVA, E/H, and sports performance training twice a week for two months. They were measured by the sports vision test and the sports performance test before and after training. After the training, there were no significant training effects on the results in sports vision. There were slight training effects in the performance tests. And after the visual training period, partially sighted people reported that they felt they could recognize surroundings better than before. It is suggested that sports visual training could be somewhat effective on the visual functions in partially sighted people.
