Abstract:
1. An activity-induced energy expenditure estimating instrument comprising: body activity information measuring means, body specifying information acquiring means, body composition information acquiring means, and activity-induced energy expenditure computing means, wherein the body activity information measuring means measures body activity information, the body specifying information acquiring means acquires body specifying information, the body composition information acquiring means acquires body composition information, and the activity-induced energy expenditure computing means stores correlation data representing correlations between the body activity information, body specifying information, body composition information, and an activity-induced energy expenditure, and calculates an activity-induced energy expenditure corresponding to the body activity information measured by the body activity information measuring means, the body specifying information acquired by the body specifying information acquiring means and the body composition information acquired by the body composition information acquiring means, by use of the stored correlation data; wherein the body activity information is acceleration, the body specifying information is a body weight, age and sex, and the body composition information is at least one selected from the group consisting of a fat free mass, a muscle amount, a fat mass, total body water and a body cell mass; and wherein the correlation data is represented by a formula: AEE=a
