Resonance Breathing and Postural Resonance: Acute Modulation of Autonomic and Hemodynamic Responses Via Arterial Baroreflex Mechanisms
Sponsor: Beijing Sport University
Summary
This randomized crossover study compared the acute autonomic and hemodynamic responses to three experimental conditions: control, resonance breathing (RB), and postural resonance (PR), in healthy young adults. Each participant completed all three sessions in randomized order, separated by a 5-day washout period. Each session included a 15-minute baseline and a 15-minute assigned condition, followed by a post-condition stress protocol consisting of a 2-minute mental arithmetic task (MAT), 5 minutes of seated rest, a 2-minute cold pressor test (CPT), and a final 5-minute recovery period. Skin sympathetic nerve activity (SKNA) and heart rate variability (HRV) were recorded continuously throughout each session, including the stress tasks and recovery periods. Blood pressure (BP) was measured intermittently at the protocol-specified time points, and pulse wave velocity (PWV) was measured at the time points specified in the study protocol.

Conditions
Interventions
Resonance Breathing
A structured intervention focusing on resonance breathing ( slow, rhythmic breathing at spontaneous resonance frequency ) . The protocol aims to acutely modulate autonomic nervous system activity and hemodynamic responses via stimulation of the arterial baroreflex.
Postural Resonance
A structured intervention focusing on postural resonance alignment. The protocol aims to acutely modulate autonomic nervous system activity and hemodynamic responses via stimulation of the arterial baroreflex. Sessions include guided breathing practice, postural adjustment, and feedback on breathing mechanics
