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.

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.
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

Skin sympathetic nerve activity
Skin sympathetic nerve activity (SKNA) was recorded non-invasively at the chest wall using a dedicated SKNA monitoring system. Measurements were obtained at baseline (pre-intervention) and immediately following completion of the resonance breathing and postural resonance intervention, to assess acute changes in sympathetic nervous system activity.
Time frame: Baseline (pre-intervention) and immediately post-intervention (within 5 minutes of intervention completion)
Changes in Resting Systolic and Diastolic Blood Pressure
Resting systolic and diastolic blood pressure were measured in a seated position using a validated automated sphygmomanometer. Measurements were collected at baseline (pre-intervention) and immediately post-intervention, to evaluate acute hemodynamic changes following the resonance breathing and postural resonance intervention.
Time frame: Baseline (pre-intervention) and immediately post-intervention (within 5 minutes of intervention completion)
Changes in Pulse Wave Velocity (PWV)
Pulse wave velocity (PWV), a non-invasive marker of arterial stiffness, was assessed using a validated vascular screening device. Measurements were obtained at baseline (pre-intervention) and immediately post-intervention, to evaluate acute changes in arterial function following the intervention.
Time frame: Baseline (pre-intervention) and immediately post-intervention (within 5 minutes of intervention completion)
