Reading aloud was associated with increases in respiratory duration, lung volume, inspiratory velocity, and the amplitude of respiratory sinus arrhythmia.
Observational (n=18)
Does reading aloud affect the amplitude of respiratory sinus arrhythmia compared to rest breathing and silent reading in adults?
Reading aloud increases the amplitude of respiratory sinus arrhythmia, supporting the active modulation of sensorimotor pathways mediating metabolic respiration during speech.
The amplitude of the respiratory sinus arrhythmia (RSA) was investigated during a reading aloud task to determine whether alterations in respiratory control during speech production affect the amplitude of RSA. Changes in RSA amplitude associated with speech were evaluated by comparing RSA amplitudes during reading aloud with those obtained during rest breathing. A third condition, silent reading, was included to control for potentially confounding effects of cardiovascular responses to cognitive processes involved in the process of reading. Calibrated respiratory kinematics, electrocardiograms (ECGs), and speech audio signals were recorded from 18 adults (9 men, 9 women) during 5-min trials of each condition. The results indicated that the increases in respiratory duration, lung volume, and inspiratory velocity associated with reading aloud were accompanied by similar increases in the amplitude of RSA. This finding provides support for the premise that sensorimotor pathways mediating metabolic respiration are actively modulated during speech production.
