Do high frequency yoga breathing and breath awareness alter heart rate variability?
High frequency yoga breathing and breath awareness alter autonomic tone, specifically reducing parasympathetic and increasing sympathetic modulation.
The results suggest that there was reduced parasympathetic modulation during and after HFYB and increased sympathetic modulation with reduced parasympathetic modulation during and after breath awareness.
