Influence of Alternate Nostril Breathing on Heart Rate Variability in Non-Practitioners of Yogic Breathing

PURPOSE: To examine cardiac autonomic modulation, as assessed by heart rate variability (HRV), following ANB in comparison to that following PB. METHODS: Twenty individuals (age: 22.3 + or - 2.9 yr) with no prior experience with ANB engaged in 30 min of both ANB and PB in a randomly assigned order....

Description
Summary:PURPOSE: To examine cardiac autonomic modulation, as assessed by heart rate variability (HRV), following ANB in comparison to that following PB. METHODS: Twenty individuals (age: 22.3 + or - 2.9 yr) with no prior experience with ANB engaged in 30 min of both ANB and PB in a randomly assigned order. ANB and PB were preceded and followed by 5 min of normal breathing (PRE, Post-ANB, and Post-PB, respectively). An electrocardiogram was recorded during all conditions for HRV analysis, along with mean arterial pressure (MAP).\RESULTS: The ANCOVA revealed InTP, InLF and InHF were greater during both Post-ANB and Post-PB compared to PRE. The ANCOVA also revealed that there were differences in the mean RR interval between conditions (p < 0.05), although post-hoc tests were not significant. InLF/lnHF and MAP did not significantly differ between conditions.
