During a baseline measurement and both exercise conditions, cortical activity was recorded using a 64-channel electroencephalographic system, and heart rate was assessed. Ratings of perceived excertion and perceived cognitive engagement were examined after each condition. To analyze power spectral density in the theta, alpha-1, and alpha-2 frequency bands, an adaptive mixture independent component analysis was used to determine the spatiotemporal sources of cortical activity, and brain components were clustered to identify spatial clusters. <jats:italic><jats:bold>Results</jats:bold>:</jats:italic> One-way repeated-measures analyses of variance revealed significant main effects for condition on theta in the prefrontal cluster, on alpha-1 in the prefrontal, central, bilateral motor, bilateral parieto-occipital, and occipital clusters, and on alpha-2 in the left motor, central, and left parieto-occipital clusters. Compared with the lower cognitive demand exercise, cortical activity was significantly higher in theta power in the prefrontal cluster and in alpha-1 power in the occipital cluster during the higher cognitive demand exercise. <jats:italic><jats:bold>Conclusion</jats:bold>:</jats:italic> The present study shows that exercise complexity seems to influence cortical processing as it increased with increasing cognitive demands.</jats:p> Human Kinetics2023 eng Physical TherapySports Therapy and RehabilitationOrthopedics and Sports MedicinePediatricsPerinatology and Child Health 0899-8493 1543-292010.1123/pes.2021-0212 1-11 L.
