The control of respiration modifies variability of the cardiac rhythm in the volunteers presenting with variations of the heliogeomagnetic factors

The present work was designed to study the modification of the relationship between variability of the cardiac rhythm (VCR) and variations of the geomagnetic factors in 20 healthy female volunteers by means of regulation of their respiration with a frequency chosen on an individual basis during 50 days. It was shown that such regulation resulted in a change of the cardiac rhythm that was indicative of the enhanced adaptive potential of the organism and the reduction of tension in its regulatory systems in response to a given physical factor. Moreover, the regulation of respiration with the desired frequency modified the relationship between variability of the cardiac rhythms of the volunteers and the variations of the heliomagnetic factors as a result of reduction of the dependence of the vegetative regulation of the cardiac function on fluctuations of the heliomagnetic activity. The results of the present study may have practical implications for modern medicine and rehabilitation because they open up the prospects for the application of the method of the regulation of respiration with a frequency chosen on an individual basis for the correction of adverse changes in the functional state of the organism under the influence of fluctuations of the heliomagnetic activity. The data obtained give reason to recommend the courses of controlled respiration for the enhancement of the adaptive potential of the human organism.
