Acute mood and EEG effects of aerobic exercise in depressed and nondepressed adults.

Thesis (Ph.D.)--The University of Alabama at Birmingham, 1992.

College undergraduates were classified as "depressed" or "nondepressed" based on Beck Depression Inventory scores. Participants were randomly assigned to either an aerobic exercise treatment involving stationary bicycling or to a low-intensity exercise treatment designed to control for nonspecific effects. EEG and cardiovascular responsivity during the performance of cognitively demanding tasks were also assessed after recovery from the experimental treatment. It was predicted that aerobic exercise would lead to significantly larger reductions in state anxiety and depression which would be paralled by relatively greater increases in the alpha frequency of the EEG. The results support equal reductions in anxious and depressed mood for depressed participants after both treatments. In general, increases in alpha were seen in both groups. Aerobic exercise led to selective increases in right temporal eyes-closed alpha in depressed participants. Frontal eyes-open alpha during anticipation of cognitive task performance was also increased for aerobic exercise participants. The aerobic participants. The aerobic exercise treatment resulted in more pronounced alpha suppression in the temporal region during performance of a Digits Backward test. Depressed and nondepressed groups showed similar levels of alpha at baseline and during neuropsychological task performance, but depressed participants showed more peripheral vasoconstriction during the performance of a visuospatial task. The results suggest that aerobic exercise may influence EEG alpha activity during anticipation and performance of attentionally demanding cognitive tasks. Additional research is necessary to establish a psychophysiological framework for the acute emotional effects of exercise.Subjects--Topical Terms:
