What was done
The authors describe the theoretical rationale and outline a clinical training manual for resonant frequency heart rate variability (HRV) biofeedback. The protocol instructs individuals to slow respiration to approximately 0.1 Hz to induce resonance between respiratory sinus arrhythmia (RSA) and underlying baroreflex-mediated oscillations.
What was found
The abstract reports no primary empirical data or quantitative numbers. It outlines the mechanism whereby breathing at approximately 0.1 Hz maximally increases heart rate oscillation amplitude and hypothesizes that this exercises and improves the efficiency of baroreflexes.
Why it matters
This paper establishes the physiological framework and standard clinical manual for resonant frequency HRV biofeedback.
Limits
The publication is a methodology manual and theoretical proposal containing no primary empirical data, sample size, or measured statistical outcomes in this report, referring to a companion paper for supporting data.
