This study aimed to investigate the effects of exercise on pupil dynamics, prefrontal haemodynamic, and salivary alpha-amylase (sAA) responses in 45 healthy graduate students. These participants were divided into two groups: a resting control group (CTL) and a very-light-intensity exercise group (EX). Participants in the EX-group engaged in a 10-min exercise at 30% O peak on a cycle ergometer. Salivary samples and pupillometry assessments were collected before the exercise, at the end of the exercise, and 5 min after the completion to evaluate changes over time. Our analysis showed that exercise induced significant changes in the secretion of salivary alpha-amylase, with elevated levels suggesting increased neuroendocrine activity linked to the arousal state triggered by exercise. In addition, functional oxyHb signals indicated greater fluctuations in the mid-left prefrontal cortex among participants in the EX-group compared to those in the CTL group, pointing to altered prefrontal haemodynamic.
本研究旨在探讨运动对 45 名健康研究生的瞳孔动力学、前额叶血液动力学和唾液α-淀粉酶（sAA）反应的影响。这些参与者被分为两组：休息对照组（CTL）和极轻强度运动组（EX）。EX 组的参与者在循环测功计上以 30%峰值氧的强度进行 10 分钟的运动。在运动前、运动结束时和运动完成后 5 分钟收集唾液样本和瞳孔计评估，以评估随时间的变化。我们的分析表明，运动引起唾液α-淀粉酶分泌的显著变化，升高的水平表明与运动引起的唤醒状态相关的神经内分泌活动增加。此外，功能氧合血红蛋白信号表明，与 CTL 组相比，EX 组参与者的中左前额叶皮层的波动更大，表明前额叶血液动力学发生改变。
