Introduction: The purpose of this study was to determine the psychological affect of walking exercise as measured by electroencephalogram (EEG) resting frontal asymmetry in persons with ID. Methods: Resting EEG frontal asymmetry (F4-F3) was collected from twelve participants to represent affective responsiveness pre and post a 20-minute treadmill walking exercise at moderate intensity. Results: The association between frontal asymmetry and reported RPE is evident. In addition, the decreased frontal asymmetry from pre-exercise to post-exercise indicates their decreased affect to walking exercise. Conclusions: Resting EEG frontal asymmetry was reflective of affective repsonsivity to exercise in persons with ID. Our finding is not consistent with previous research in the typical population who showed increased frontal brain asymmetry after exercise. The decreased experience of affect pronounced after 20-minute brisk treadmill walking in persons with ID may explain their low motivation to exercise adherence. Therefore, extra motivating factors, such as music or challenging task maybe needed to accomplish exercise and its related benefits in persons with ID.
