| Outline of Final Research Achievements |
In particular, parasympathetic nerve activity as well as arterial baroreflex sensitivity reduces with aging process. In elderly patients with coronary artery disease, high parasympathetic nerve activity and low sympathetic nerve activity have been observed in right lateral decubitus position compared with supine and left lateral decubitus positions. However, little research has been conducted to determine sex and age differences in autonomic nervous activity in different positions, i.e., supine, left recumbent, and right recumbent positions. The aim of this study was to evaluate the effect of the left and right recumbent positions on heart rate variability in elderly was the lowest among the three positions regardless of sex. In elderly men, the LF/HF ratio in right recumbent position was significantly lower than that in supine position. Right recumbent position may attenuate cardiac sympathetic nerve activity in elderly adult men.
