SYSTEM FOR MEASURING AMOUNT OF ACTIVITY

摘要

The system for measuring the amount of activity calculates the exercise index (EX) indicative of the positive amount of exercise performed for a predetermined period of measurement and the life activity index (DA) indicative of the amount of exercise of daily life activity based on the activity strength measured continuously, and displays the combination of these indexes, i.e. activity elements A(x, y), on an X-Y matrix plane. The exercise index (EX) is calculated by a first operating means by totalizing the product of a time when the activity strength exceeds a predetermined reference value and its activity strength over the measurement period. The life activity index (DA) is calculated by a second operating means by dividing energy consumption of a user over the predetermined period by the basal metabolic rate. The energy consumption is determined as a function of the activity strength per unit time below the reference value and a data indicative of the physical features of a user, and the basal metabolic rate is calculated based on the physical features of a user. The data of physical features is held on a personal information data table in the system.
