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.本發明的課題在於,為了按照個人差異而簡單且高精度地測定出消耗熱量。本發明之消耗熱量測定裝置(10),是根據檢測出的被測定者的心跳數來測定活動時的消耗熱量之裝置,其具備:事前處理部(40)、心跳數接收部(35)、消耗熱量算出部(50)。事前處理部係具備第1個人資料產生部及第2個人資料產生部;該第1個人資料產生部,係設定包含年齡、性別、身高及體重之被測定者的個人狀態,並依照所設定的個人狀態來產生第1個人資料;該第2個人資料產生部,係設定被測定者的環境狀態,按照所設定的環境狀態來產生第2個人資料。心跳數接收部,係接收所檢測出的心跳數。消耗熱量算出部,係依據所接收的心跳數和在事前處理部產生的第1及第2個人資料來算出消耗熱量。10‧‧‧消耗熱量測定裝置21‧‧‧操作鍵22‧‧‧顯示部30‧‧‧心跳計35‧‧‧心跳數接收部40‧‧‧事前處理部41‧‧‧第1個人資料產生部42‧‧‧第2個人資料產生部43‧‧‧安靜時氧攝取量算出部44‧‧‧彈性點設定部45‧‧‧係數設定部46‧‧‧最大氧攝取量設定部47‧‧‧預測最大心跳數算出部50‧‧‧消耗熱量算出部51‧‧‧心跳數判斷部52‧‧‧心跳儲備率算出部53‧‧‧計算部
