Heart rate changes associated with EMG and alpha biofeedback.
Physiological concomitants of relaxation are needed to characterize objectively the response to biofeedback training. Ss (N = 30) received either alpha, EMG, or no biofeedback training. Heart rate, EMG, and alpha activity were measured in all groups. Increases in alpha and decreases in EMG were noted in their respective feedback groups. Heart rate, however, was not related systematically to these changes, and no significant changes in heart rate occurred in any group.
