The purposes of this study are to evaluate the effect of the posture and the respiratory rate on the heart rate variability (HRV) indexes during sitting (ExperimentI), and to assesss the effect of mental stress on cardiac autonomic nervous activity by using the corrected HRV indexes (ExperimentII). Since the effect of respiratory rate that had kept influencing the HRV indexes during sitting was the same in the supine posture, the HRV correction formula by respiratory rate in the supine posture were found possible to use to correct of the HRV indexes, even in sitting as well. The mental stress was carried out by body contacts with others, and its effect was evaluated at the corrected HRV indexes in sitting. As a result, the mental stress decreased the heart rate and increased the corrected HF, representing that mental stress causes the increase of the cardiac parasympathetic nervous activity.
