The immediate and delayed effects of a single bout of steady-state aerobic exercise on 19 young adults' (mean = 21.1 yr) sensory sensitivity (critical flicker fusion, CFF) and executive function (modified Paced Auditory Serial Addition Task, PASAT) were assessed.
Tests were performed before exercise, five times during 40 min of ergometer cycling at 90% ventilatory threshold, and three times during a 30-min postexercise period. In a separate control session, each participant performed the same sequence of tests while seated on the ergometer without pedaling.
ANOVA were performed separately on CFF and PASAT scores, which compared performance during exercise and nonexercise conditions at nine time points. Planned ANOVA of CFF scores revealed that the participants' sensory discrimination increased during exercise and then quickly returned to baseline levels immediately after exercise. PASAT scores did not change during or after exercise.
Exercise-induced arousal facilitates sensory processes involved in stimulus detection but does not influence the updating component of executive processing.
评估单次稳态有氧运动对 19 名年轻成年人（平均年龄=21.1 岁）的感官敏感性（临界闪烁融合频率，CFF）和执行功能（改良的听觉连续加法任务，PASAT）的即时和延迟影响。
在运动前、在 90%通气阈值的测力计自行车上进行 40 分钟的运动期间的五次，以及在 30 分钟的运动后期间的三次进行测试。在单独的对照会话中，每个参与者在不踩踏板的情况下坐在测力计上执行相同的测试序列。
对 CFF 和 PASAT 分数分别进行方差分析，该分析比较了在 9 个时间点的运动和非运动条件下的表现。对 CFF 分数的计划方差分析表明，参与者的感官辨别力在运动期间增加，然后在运动后立即迅速恢复到基线水平。PASAT 分数在运动期间或之后没有变化。
运动引起的觉醒促进了刺激检测中涉及的感觉过程，但不影响执行处理的更新成分。
