Diaphragmatic breathing training has become important treatment of anxiety disorders, anxiety-related illnesses, and pain control. There is a consensus in the literature on most issues of breathing training. However, there is disagreement regarding the desired length of the inspiration compared to the length of the expiration. Some practitioners and researchers advocate equal lengths; some advocate longer expirations. The few attempts to clarify the issue have not been conclusive.

520 $a Diaphragmatic breathing training has become important treatment of anxiety disorders, anxiety-related illnesses, and pain control. There is a consensus in the literature on most issues of breathing training. However, there is disagreement regarding the desired length of the inspiration compared to the length of the expiration. Some practitioners and researchers advocate equal lengths; some advocate longer expirations. The few attempts to clarify the issue have not been conclusive.
520 $a This study hypothesized that prolonged expiration would enhance parasympathetic activation and produce greater relaxation. The length of inspiration and expiration was manipulated during slow diaphragmatic breathing and the effect on autonomic arousal measured. Autonomic arousal was measured by skin conductance level, blood volume pulse, finger temperature, heartrate, respiratory sinus arrhythmia (RSA), and respiration rate. Participants were stressed with mental arithmetic before each treatment. Three treatment conditions were tested: a 2:4 inspiration to expiration (IE) ratio, a 3:3 ratio, and a 4:2 ratio. The lengths of inspiration and expiration were controlled by having participants self-pace by slowly counting during respiration. Each of the 34 participant experienced all three treatment conditions in a within-subjects design.
520 $a Except for RSA, no significant differences were found among the three ratios. RSA supported the 2:4 ratio. The 4:2 ratio was difficult for the participants to accomplish. Because prior research also suggested that prolonged expiration was more relaxing, clinicians should feel confident employing slow deep abdominal breathing with prolonged expiration or equal IE ratios.
