Resonant breathing and baroreflex sensitivity

Study demonstrating that breathing at resonance frequency (4-6 breaths/min) maximizes baroreflex sensitivity and produces greatest HRV amplitude.

Resonance Frequency

  • Optimal: 4.5-6 breaths/min
  • Individual variation: 4-7 breaths/min
  • 5.5 breaths/min typically optimal

HRV Enhancement

RSA amplitude 3-5x greater than spontaneous breathing.

Outcomes

  • resonance-frequency-breathing
    Optimal resonance frequency at 4.5-6 breaths/min; RSA amplitude 3-5x greater than spontaneous breathing
