Physical activity monitor
First Claim
1. Physical activity monitor comprising a memory 8 and means for entering first body data of a user into that memory, means for measuring one or a plurality of physiological properties that are dependent on the user'"'"'s physical activity and serve as activity indicators, a data processing unit for determining the user'"'"'s energy expenditure (P) on the basis of the body data and of the values of the activity indicators by evaluating an energy expenditure function, and a display for displaying at least one item of information related to that energy expenditure (P), characterized in that a calibration unit for controlling the sequence of a calibration procedure is provided by which the activity indicators are measured during one or a plurality of reference activities (R1, R2, R3) of the user, and an indicator reference indicating the user-specific sensitivity of the activity indicators is derived from these reference values (TR1, TR2, TR3) and stored as a complement to the first body data.

Abstract
The invention relates to a physical activity monitor comprising means for entering known body data such as size, gender, and weight of a monitor user, means for measuring at least one physiological parameter that is a function of the user'"'"'s physical activity and serves as an activity indicator, for example heart rate and/or a movement intensity derived from acceleration, a calibration procedure for determining the user-specific sensitivity of the activity indicators and for storing them as a part of the user'"'"'s body data, as well as an energy expenditure function that allows to determine the user'"'"'s energy expenditure on the basis of the mentioned body data and of the values of the activity indicators.
