R (min –1 ) × 0,0167 (Hz),(RvFr. – respiratory bound frequency regarded as vagusactivity in the frequency zone HF or LF, Fr.R – averagevalue of respiratory frequency) (TABLES 2–5, Fig. 2).The position of sitting with full yoga breathing (intervalT6) was characterised by a distinct slowdown of respiratoryrhythm of less than 9 cycles/min. and a simultaneousenhancement of respiratory volume. Calculated respiratoryfrequency in these positions assumed just the relationshipto dominant activity only, in the zone of frequency componentLF. In the literature, the dominant frequency in thiszone is related to baroreceptor activity. In our researchthere is just a frequency shift of frequency bound to respirationfrom the HF zone into the frequency zone of LFdepending on the respiration frequency. The dominantfrequency bound to respiration that we regard as vagus

Residual dominant and other subdominantfrequencies in zone HF under these conditions donot have a direct bearing on the respiratory bound vagusactivity. Under the given conditions it is probably possibleto regard frequency activity and its modulation inthis zone as parasympathetic activity originating fromsources other than vagus activity bound to respiration.2.
