Quantitative Evaluations of Health Promotion Methods Using Peripheral Blood Flow (2)

We measured age dependence of tail angles of Americans of European origin and compared it with that of Japanese. From the measurements, we found a relationship between tail angle and pulse duration. Healthy subjects trained in sports with longer pulse duration tended to show lower tail angle. We proposed a modified attractor construction method which gives us tail angle independent of pulse duration. There was no significant difference between modified tail angles and age dependence of Americans and Japanese. Modified tail from around 20 to 40 degrees. The low values of the distribution decrease gradually or stay constant, in contrast, high values decrease more clearly.
