Abstract

A caloric consumption measuring device measures a caloric consumption of a user during an activity. The caloric consumption measuring device includes a first personal data creating component, a second personal data creating component, a heart rate input component, and a caloric consumption calculating component. The first personal data creating component sets at least one personal physical condition of the user and creates first personal data based on the set personal physical condition. The second personal data creating component sets at least one environmental condition of the user and creates second personal data based on the environmental condition. The heart rate input component receives data indicative of a detected heart rate. The caloric consumption calculating component calculates the caloric consumption based on the detected heart rate that was received and the first and second personal data created by the first and second personal data creating components.
