Estimation of Exercise Intensity in “Exercise and Physical Activity Reference for Health Promotion”

Abstract

To maintain or promote the health condition of elderly citizens is quite important for Japan. Given the circumstances, the Ministry of Health, Labour and Welfare has established the standards for the activities and exercises for promoting the health, and quantitatively determined the exercise intensity on 107 items of activities. This exercise intensity, however, requires recording the type and the duration of the activity to be calculated. In this paper, the exercise intensities are estimated using 3D accelerometer for 25 daily activities. As the result, the exercise intensities were estimated to be within the root mean square error of 0.83 METs for all 25 activities.
