我们研究了以 50% 峰值摄氧量的中等强度进行 30 分钟的自行车运动，与休息 30 分钟相比，对图片前景刺激的情绪反应变化的影响，这些前景可靠地引发了不愉快、中性和愉快的影响。通过自我报告效价（从不愉快到愉快）和唤醒度（从低到高）以及 13 名女性和 21 名男性（24 +/- 3 岁）的额叶和顶叶脑电图 (EEG) 活动的半球不对称性 (R-L) 来测量情绪反应。与休息后相比，运动后对不愉快幻灯片的反应的自我报告有所减少，但α频率的效价和额叶不对称性的自我报告总体上没有变化。即便如此，额叶区域的 β 频率以及顶叶区域的 α 和 β 频率的不对称反应存在差异，表明运动后与休息后相比，左额叶和右顶叶区域的活动减少。我们的结论是，中等强度的自行车运动通常不会改变对愉快和中性图片的情绪反应，但可能会减少暴露于不愉快刺激时的情绪唤起。 (c) 2006 Elsevier Inc. 保留所有权利。
We examined the effects of 30 min of cycling exercise at a moderate intensity of 50% peak oxygen uptake, compared to 30 min of rest, on changes in emotional responses to pictorial foreground stimuli that reliably elicit unpleasant, neutral, and pleasant affect. Emotional responses were measured by self-reports of valence (unpleasant to pleasant) and arousal (low to high) and by hemispheric asymmetry (R-L) of frontal and parietal brain electroencephalographic (EEG) activity in 13 females and 21 males (24 +/- 3y). Compared to after rest, self-reports of arousal in response to unpleasant slides were diminished after exercise, but self-reports of valence and frontal asymmetry of alpha frequencies were generally unchanged. Even so, there were differential responses in asymmetry in the beta frequencies in the frontal region and for alpha and beta frequencies in the parietal region, indicative of decreased activity in the left frontal and right parietal regions after exercise compared to after rest. We conclude that moderately intense cycling exercise generally does not alter emotional responding to pleasant and neutral pictures, but may reduce emotional arousal during exposure to unpleasant stimuli.
