Electroencephalography has been used to establish the relationship among cortical activity, exercise and mood,
such as asymmetry, absolute and relative power. The purpose of this study was to systematically review the
influence of cortical activity on mood state induced by exercise. The Preferred Reporting Items in Systematic
reviews and Meta-Analyses was followed in this study. The studies were retrieved from MEDLINE/PubMed, ISI Web
of Knowledge and SciELO. Search was conducted in all databases using the following terms: EEG asymmetry,
sLORETA, exercise, with affect, mood and emotions. Based on the defined criteria, a total of 727 articles were found
in the search conducted in the literature (666 in Pubmed, 54 in ISI Web of Science, 2 in SciELO and 5 in other data
sources). Total of 11 studies were selected which properly met the criteria for this review. Nine out of 11 studies used
the frontal asymmetry, four used absolute and relative power and one used sLORETA. With regard to changes
in cortical activity and mood induced by exercise, six studies attributed this result to different intensities, one to
duration, one to type of exercise and one to fitness level. In general, EEG measures showed contradictory
evidence of its ability to predict or modulate psychological mood states through exercise intervention.
Keywords: Absolute and relative power, aerobic exercise, affect, asymmetry, brain.
