摘要

篮球运动员的视觉和神经特征可能会影响他们的运动表现。本文对20名篮球运动员和20名非运动员进行了运动视觉测试和神经效率测试。实验刺激是为了确定图片上是否有一个球。相关视觉数据由眼动仪获取。脑区活动数据通过功能磁共振成像(fMRI)获得。对数据进行了处理和分析。结果表明,A组(篮球运动员)的反应时间为526.78±75.36 ms,正确率为94.12±3.45%,均优于B组(非运动员)。A组的注视时间和注视频率分别为204.77±40.23 ms和1.67±0.41次,表明A组的注视稳定性较好,且A组激活的脑区比b组少。实验结果验证了篮球运动员在消耗较少的神经资源的情况下具有更好的目标捕捉能力和更高的神经效率。

Effects of Motion Vision and Neural Efficiency On Target Capture in Basketball Players
Basketball players' visual and neurological characteristics may affect their sports performance. In this paper, 20 basketball players and 20 non-athletes received a motion vision test and a neurological efficiency test. The experimental stimulus was to determine whether there was a ball on the picture. The relevant visual data were obtained by an eye tracker. The brain area activity data were obtained by functional magnetic resonance imaging (fMRI). The data were processed and analyzed. The results showed that the reaction time of group A (basketball players) was 526.78 ± 75.36 ms, and the correct rate was 94.12 ± 3.45%, both of which were better than group B (non-athletes). The fixation duration and fixation frequency of group A were 204.77 ± 40.23 ms and 1.67 ± 0.41 times, suggesting good fixation stability, and group A activated fewer brain areas than group B. The experimental results verify that basketball players have better target capture ability and higher neural efficiency while consuming fewer neural resources.
