Outline of Final Research Achievements

A respiration-posture feedback system was developed to intervene human breathing. A small air chamber placed under a subject’s back deflates and inflates to make a subject’s postures change and so to change the breathing. The results showed that the subject’s respiration was successfully deepened, getting longer in the latency and increase of the volume, and that the enhancement of parasympathetic nervous system activity. Meanwhile, the effect on endocrine system in terms of a stress hormone secretion has varied widely among individuals.
