| Outline of Final Research Achievements |
Little research has been conducted on age-related differences in autonomic nervous activity and circulation between the various recumbent positions. The purpose of the present study was to evaluate elderly subjects show differences in the autonomic nervous activity and circulation between the 3 positions (supine, right lateral decubitus, and left lateral decubitus position). We performed electrocardiographic measurements for 50 elderly subjects (63-85 years). No significant differences were observed in mean BP, low frequency HRV, high frequency HRV, and their ratio. However, in the left lateral decubitus position, HR was significantly lower than in the supine position. In contrast, the LF/HF ratio in the right lateral decubitus position was significantly lesser than that in the supine position the elderly .
