Resonance Frequency Breathing May Support Runners' Recovery by Raising HRV
Resonance frequency breathing uses a personalized slow pace, typically five to six breaths per minute, to raise heart rate variability and activate the parasympathetic nervous system. Psychologist Erin Ayala explains how runners can test their own rate with a chest strap and an app, and cites small studies linking HRV biofeedback to recovery and 5K performance.
