我们研究了急性运动对视觉刺激的反应时间的影响，这些视觉刺激出现在视野的中心部分和周边。12名参与者在休息时和骑自行车时在两种视觉条件下以65%的峰值摄氧量进行反应时间任务。我们使用圆形黑白白色棋盘图案作为视觉刺激。参与者被要求通过释放响应按钮来尽可能快地响应视觉刺激的模式反转。反应时间分为运动前时间和运动时间。外周条件下运动前时间在运动期间（平均值+/- SE; 195.9 +/- 7.9 ms）比静息时（183.7 +/- 6.8 ms）显著增加（p < 0.025）。在中心条件下，静息（185.3 +/- 7.6 ms）和运动（188.4 +/- 6.6 ms）时的运动前时间没有差异。这些数据表明，与对视野中央部分的视觉刺激的反应能力相比，对视野周边的视觉刺激的反应能力容易受到中度至重度运动的影响。运动引起的唤醒水平的增加和随之而来的注意力集中的缩小可以解释目前的结果。
We examined the effects of acute exercise on reaction time to Visual stimuli presented in the central portion and periphery of the visual field. Twelve participants performed reaction time tasks at rest and during cycling at 65% peak oxygen uptake in two visual conditions. We used circular black-and-white checkerboard patterns as visual Stimuli. The participants were asked to respond as quickly as possible to pattern reversal of the visual Stimulus by releasing a response button. Reaction time was fractionated into Premotor time and Motor time. Premotor time in the peripheral condition significantly increased (p < 0.025) during exercise (mean +/- SE; 195.9 +/- 7.9 ms) from that at rest (183.7 +/- 6.8 ms). Premotor time in the central condition did not differ between at rest (185.3 +/- 7.6 ms) and during exercise (188.4 +/- 6.6 ms). These data suggest that the ability to respond to visual stimuli presented in the periphery of the visual field is vulnerable to moderate to severe exercise, as compared with the ability to respond to visual stimuli presented in the central portion of the visual field. An exercise-induced increase in arousal level and a consequent narrowing of attentional focus would explain the present results.
