Objective of the study was to explore the effects of rhythmic workloads on the intra-hemispheric coherent communication formation process and on the heart rate control variability. Subject to the study were 30 young women of 17-20 years of age. The coherent communication was tested by a computerized Neuron-Spectrum Electroencephalograph System (made by NeuroSoft Research and Production Company based in Ivanovo, Russia).
The study showed that the low-frequency rhythmic workloads are associated with the intra-hemispheric short coherent communications being desynchronized, whilst the higher-frequency movements were found to help synchronize the cerebral electric activity. These changes were found to affect the heart rate control system, with the growing movement frequency being of strengthening effect on the autonomous control mechanism. We assume that the specific effects of different physical activity on the cortical processes are basically due to bioelectric activity patterns with variable coherence rates being formed in the cortex, the patterns being able to modulate the centralization level of the vegetative system control mechanisms.

Keywords: heart rate variability, spectral analysis, coherency, rhythmic workload, electroencephalographic indices, EEG rhythms.
