Abstract
A device for monitoring the physical activity of a living being is disclosed. In one aspect, there is a data input module configured to receive information about the living being'"'"'s heart beat rate value, motion intensity and anthropometric characteristics. Further, there is an activity recognition and storage module configured to detect, from information received about the living being'"'"'s motion intensity, the living being'"'"'s activity and to store information about the living being'"'"'s heart beat rate value and the motion intensity associated with that detected activity. Further, there is a heart beat rate analysis module configured to determine, from a plurality of heart beat rate values associated with each detected activity, statistics of the distribution of heart beat rate values for each activity or a subset of activities. Further, there is a fitness estimation module configured to calculate, using the information from the heart beat rate analysis module and the anthropometric characteristics, a cardiorespiratory fitness level of the living being.
