Slowed respiration training

A method of slowed respiration rate (RR) training is described that uses visual feedback of the respiratory cycle. Subjects assigned to the slowed RR training procedure were compared with subjects assigned to either a traditional frontal electromyographic (EMG) biofeedback condition or a control condition where no feedback was presented. RR, frontal EMG, heart rate, digital temperature, and skin conductance level were monitored simultaneously. The results indicated that RR training was effective in reducing RR, that RR training had little systematic effect on the other physiological variables, and the frontal EMG procedure did not in itself reduce RR. The advantages of the current methodological approach and the importance of respiration training were discussed along with a literature review. The relationship between RR training and the complexities of respiratory phenomena was discussed, as well as ways that future research using this method may help clarify current issues within respiration training.This research was supported by grant No. 2-S06RR08038-19 from the National Institutes of Health. The able work of Nora Barker and Robert Longoria is acknowledged, who served as biofeedback technicians.
