Abstract
Heart rate monitor system and method of determining a warming-up status of a user A heart rate monitor system is provided which comprises an optical heart rate sensor (100) configured to measure or determine a heart rate of a user and to output an output signal (101). The heart rate monitor system furthermore comprises an analyzing unit (200) configured to analyze an output signal (101) from the heart rate sensor (100) and to determine a warming up status of a user based on the analyzed output signal (101) from the optical heart rate sensor (100), wherein the analyzing unit (200) comprises a signal analyzer (210) configured to analyze at least one of an AC component of the output signal (101), a DC component of the output signal (101), and a pulse morphology of the output signal (101) and a warm-up detector unit (220) configured to detect a warm-up status of the user based on a detected blood perfusion according to signal characteristics of the AC component, the DC component or the pulse morphology of the output signal (101).
