| Research Abstract |
The present study was designed to examine the effect of heart rate variability biofeedback (HRV-BF) on the cardiorespiratory resting function (CRF) during sleep in daily life. Forty-five young adults were randomly assigned to one of three groups: HRV-BF, Autogenic Training (AT), and control. Participants in the HRV-BF were told to use a BF device before bedtime, those in the AT were asked to listen to a recorded instruction before bedtime, and those in the control were asked to engage in habitual activity before bedtime. Pulse wave signal during sleep at their own residences was measured for 3 nights. Baseline data were collected on the 1st night of measurements, followed by 2 successive nights for each condition. CRF was assessed as the amplitude of high-frequency (HF) component of heart rate variability. HF component increased during sleep in the HRV-BF, although it remained unchanged in the AT and control. These results suggest that HRV-BF before sleep may improve CRF during sleep.
