HEART RATE VARIABILITY (HRV) BIOFEEDBACK TRAINING IMPROVES POSITIVE AFFECT AND HRV COMPONENTS IN SOCIALLY ACTIVE ELDERLY

Heart Rate Variability (HRV) is a noninvasive measure extracted from anelectrocardiogram that reflects the activity of the sympathetic and parasympathetic branches of the heart. Higher HRV is associated with good health and emotional regulation. HRV biofeedback is a type of biofeedback that specifically involves respiratory rate modification (decrease in frequency and increase in amplitude) to increase synchronization between the respiratory rate and heart rate. This technique can improve HRV and positive moods.
