This study investigates the comparison of autonomic nervous and cardiovascular responses in young and elderly subjects during abdominal breathing. RR interval responses during the abdominal breathing were similar change to the response during the spontaneous breathing in both young and elderly subjects. The abdominal breathing significantly increased the activities in parasympathetic nervous response compared before the abdominal breathing in young and elderly subject. The urine noradrenaline concentration of the abdominal breathing decreased compared to that of resting state before abdominal breathing not only in young subjects, but also in elderly. It is suggested that the abdominal breathing might be the method to induce to relaxation at any age. Therefore, the abdominal breathing may be available to relieve the dyspnea in COPD patients.
