Peripheral visual reaction time in Japanese Sports players

周边视觉RT长于中央视觉RT的反应时（RT）的增量。足球运动员比非运动员表现出更短的RT，这表明足球运动员在周边和中央视野中具有更快的知觉反应。我们研究了RT的周边视野的实践效果，以验证推测，周边刺激的反应速度提高与实践，显示RT的周边视野减少与实践。更有趣的是，练习对周边视野RT的影响扩展到了中央视野RT，反之亦然。在这项研究中观察到的转移效应可能表明，RT与实践的减少，导致中央和外周RT任务之间的共同的中枢神经系统的处理时间减少。当视觉刺激随机出现在包括中央和周边视野的大面积视野内时，注意力被定向到中间位置。这一发现可能表明，受试者，有意识或无意识地，采取的策略，以定向注意到中间位置，以尽可能快地响应所有的刺激内的大面积的视野。RT的周边视野增加工作量以上的通气阈值（VT），而有实际的RT没有变化，在运动过程中低于VT后立即。对这些结果的一个可能的解释可能是，在力竭运动期间，大脑区域的短暂代谢失衡恶化了对外周刺激的反应速度

Peripheral visual RT was longer than central visual RT given an increment in Reaction Time (RT). Soccer players showed shorter RTs than nonathletes, suggesting that soccer players have quicker perceptual response in peripheral and central visual fields. We examined the practice effect on RT for the peripheral visual field in order to verify the speculation that speed of response to a peripheral stimulus improves with practice, showing that the RT for the peripheral visual field decreases with practice. More interestingly, the practice effects on the RT for the peripheral visual field extended to RT for the central visual field, vice versa. The transfer effects observed in this study may suggest that the decrease in the RT with practice have resulted from a decrease in the central nervous system's processing time in common between central and peripheral RT tasks. Attention was oriented to intermediate locations when a visual stimulus was randomly presented within the large area of the visual field including central and peripheral visual fields. This finding may suggest that subjects, consciously or unconsciously, adopt the strategy to orient attention to intermediate location in order to respond as quickly as possible to all stimuli presented within the large area of the visual field. RT for the peripheral visual field increased at workload above the Ventilatory Threshold (VT), while there were practical no changes in the RT during exercise below and immediately after the VT. One possible explanation for these results may be that the transient metabolic imbalance in the brain regions during exhaustive exercise deteriorated the speed of response to a peripheral stimulus
