Summary

This study aimed to compare the acute autonomic and hemodynamic effects of two arterial baroreflex resonance interventions-Resonance Breathing (RB) and Postural Resonance (PR)-in healthy young adults. Methods: A randomized crossover design was conducted in 27 healthy participants (aged 18-25). Each participant completed three experimental sessions (control, RB, and PR) separated by a 5-day washout period. Each session included a 15-minute baseline, a 15-minute intervention, and a 5-min recovery phase. Continuous recordings of skin sympathetic nerve activity (SKNA) and heart rate variability (HRV) were collected throughout each session, while blood pressure (BP) and pulse wave velocity (PWV) were measured before and after the interventions.

Conditions

• Autonomic Nervous System Disease

Interventions

Type	Name	Description
BEHAVIORAL	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.
BEHAVIORAL	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
