Alternate Nostril Breathing at Different Rates and its Influence on Heart Rate Variability in Non Practitioners of Yoga
Introduction: Heart rate variability is a measure of modulation in autonomic input to the heart and is one of the markers of autonomic functions. Though there are many studies on the long term influence of breathing on HRV (heart rate variability) there are only a few studies on the immediate ef...

| description | Introduction: Heart rate variability is a measure of modulation
in autonomic input to the heart and is one of the markers of
autonomic functions. Though there are many studies on the
long term influence of breathing on HRV (heart rate variability)
there are only a few studies on the immediate effect of breathing
especially alternate nostril breathing on HRV. This study focuses
on the immediate effects of alternate nostril breathing and the
influence of different breathing rates on HRV.
Materials and Methods: The study was done on 25 subjects
in the age group of 17-35 years. ECG and respiration were
recorded before intervention and immediately after the subjects
were asked to perform alternate nostril breathing for five
minutes.
Results: Low frequency (LF) which is a marker of sympathetic
activity increased, high frequency (HF) which is a marker of
parasympathetic activity decreased and their ratio LF/HF which
is a marker of sympatho/vagal balance increased immediately
after 6 and 12 minutes in comparison to baseline values whereas
there was no significant difference in the means of these
components when both 6 and 12 minutes were compared.
Conclusion: Immediate effects of alternate nostril breathing on
HRV in non practitioners of yogic breathing are very different
from the long term influence of yogic breathing on HRV which
show a predominant parasympathetic influence on the heart. |
