Paced abdominal breathing and EMG responsivity.
5 subjects participated in a within-subjects design to determine the effect of paced abdominal breathing on EMG levels. After training in thoracic and abdominal breathing, each subject's respiration performance and EMG levels were assessed in both breathing modes via a counterbalanced A-B-A-B reversal design. Reliable effects of respiration training were observed in both breathing modes. No effects were observed on EMG measures. The results were discussed in relation to literature on approaches to respiration training which may target specific arousal indices other than electromyogram activity. The utility of dovetailing complementary treatment techniques such as respiration training and relaxation training which are specific to particular arousal indices was discussed.
