HRV Myths: Successful HRV Biofeedback Training Always Produces a 0.1 Hz LF Peak

If you train your client using a resonance frequency protocol, their target breathing rate might fall between 4.5-6.5 bpm for adults and as high as 8 bpm for children. The peak frequency (e.g., the highest amplitude frequency) depends on your client’s breathing rate. Although breathing at 6 bpm yields a 0.1 Hz peak (6/60 = 0.1 Hz), 5 bpm creates a 0.08 Hz peak (5/60 = 0.083 Hz).
