Abstract
It is necessary to provide health management and abnormality countermeasure systems for elderly persons with the advancement of an aging society. The application of health management for aging people using a pedometer was examined in this study. It is considered that the number of steps correlates strongly with the amount of physical exertion. Circadian fluctuation and the long term change of steps for the elderly subjects were analysed. As the result, the physical activity can be estimated by the number of steps and it is able to apply to health management. It could be also recognized whether the subject lives their life as usual using the steps characteristic or not. The steps of an elderly subject (woman, over 85 years old) is extremely low compared with one for a middle-age subject. The middle-age subject had a week痴 period in the steps characteristic. In the period, the subject had a nearly constant number of steps on Monday to Friday and a high steps number on Saturday and Sunday because of playing tennis. This study was carried out with restricted subjects. It is necessary to examine the characteristics of more subjects. However, it is thought that a trend is shown.
