Resonance Breathing and Postural Resonance: Acute Modulation of Autonomic and Hemodynamic Responses Via Arterial Baroreflex Mechanisms

China30 participantsStarted 2024-05-01

Plain-language 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.
