 The aim of the present study was to clarify how differences in the abdominal breathing pattern effects the activity of the autonomic nervous system. Twelve healthy female subjects, supine on the bed, were instructed to practice two types of abdominal breathing, namely, 4 second-inhalation and 6 second-exhalation, and 5 second-inhalation-exhalation. Each breathing pattern was continued for 3 minutes. Autonomic nervous activity was evaluated before and immediately, after 15 min, 30 min and 45 min from the beginning of the abdominal breathing, with power spectral analysis of heart rate variability. In the 5 second-inhalation-exhalation pattern, heart rate significantly decreased and HF (high frequency)power, an index of activity of the parasympathetic nervous system, significantly increased after 30 and 45 minutes. On the other hand, in the 4 second-inhalation and 6 second-exhalation pattern, heart rate and HF power showed significant decrease and increase respectively, after 15, 30, and 45 minutes. The results demonstrated that abdominal breathing with the 4 second-inhalation and 6 second-exhalation pattern had superior in the parasympathetic nervous system compared to the 5 second-inhalation and exhalation pattern.
