Research has shown that frontal brain activation, assessed via electroencephalographic (EEG) asymmetry, predicts the post-exercise affective response to exercise among adults. Building on this evidence, the present study investigates the utility of resting cortical asymmetry for explaining variance in the affective response both during and after exercise at two different intensities among healthy adolescents. Resting EEG was obtained from 98 adolescents (55% male), who also completed two 30-min exercise tasks on a cycle ergometer at a moderate and hard intensity. Affect (as measured by the Feeling Scale) was assessed prior to exercise, every 10min during exercise, immediately post-exercise, and 10min post-exercise. When moderate exercise was performed first, resting frontal cortical asymmetry was related to the affective response to moderate exercise, such that left-dominant adolescents reported more positive affect compared to right-dominant adolescents. When hard exercise was performed first, the association was not significant. The results are interpreted in light of current theory related to affect in response to exercise.
研究表明，通过脑电图（EEG）不对称性评估的额叶脑激活情况可预测成年人运动后的情感反应。基于这一证据，本研究调查了静息皮质不对称性在解释健康青少年在两种不同强度运动期间及运动后情感反应差异方面的效用。从98名青少年（55%为男性）获取静息脑电图，他们还在自行车测力计上以中等强度和高强度完成了两项30分钟的运动任务。在运动前、运动期间每10分钟、运动后即刻以及运动后10分钟评估情感状态（通过情感量表测量）。当先进行中等强度运动时，静息额叶皮质不对称性与对中等强度运动的情感反应相关，即左优势青少年比右优势青少年报告的积极情感更多。当先进行高强度运动时，这种关联不显著。根据当前与运动反应中的情感相关的理论对结果进行了解释。
