Interhemispheric Differences in Indices of α Activity Spectral Power Electroencephalogram during Bicycle Ergometry

Аннотация

An EEG study during bicycle ergometry in the prone position with the load growing stepwise to submaximal heart rate was carried out in 30 volunteers in order to investigate the spectrum parameters and interhemispheric differences in α activity on the encephalogram. Comparative analysis of EEG data showed a statistically significant increase in α power indices in both hemispheres at the final stage of aerobic exercise and in the course of recovery period with the highest power values recorded in the left hemisphere. Analysis of interhemispheric differences demonstrated right-hemisphere activation during the entire period of the research.
