Birukova E. Heart rate variability of subjects with different types of vegetative regulation under the influence of controlled breathing with individually chosen frequency

Thesis for a candidate degree of biological sciences on speciality 03.00.13 - physiology of man and animals - Taurida National V.I. Vernadsky University, Simferopol, 2010. The thesis is devoted to the comprehensive study of heart rate variability (HRV) of subjects with different types of vegetative regulation under the influence of controlled breathing (СВ) with individually fitted frequency. As a result of the research we have established that the CB, the frequency of which corresponds to the maximum peak power at low frequencies, the spectrum of cardiac rhythm, is a powerful way to control heart rhythm and the functional state of the cardiorespiratory system of examinees with different types of autonomic regulation, that is evidenced by the optimization of HRV, increased tolerance of the cardiovascular system to submaximal exercise and increased synchronization of cardiac and respiratory rhythms.
