Acute effects of singing on cardiovascular biomarkers.

ABSTRACT:

Background

Singing is a physical activity involving components of the vagal nerves manifested as changes in cardiac autonomic regulation.

Aims

The aim of this pilot study is to investigate the acute effects of singing on biomarkers of cardiovascular health.

Methods

Adult subjects were recruited from cardiology clinics to participate in a single 90-min study visit. Vascular function was measured at the fingertips with peripheral arterial tonometry (PAT) before and after singing to a 14-min video led by a voice expert. Heart rate variability (HRV) was measured with a chest strap sensor at baseline, during, and after singing. PAT measurements were expressed as reactive hyperemia index (RHI) and Framingham reactive hyperemia index (fRHI). Measures of HRV included root mea
