The cycling computer uses HRmax, HRsit and VO2max values for estimating your energy expenditure.

1. HRmax (Maximum heart rate)
HRmax is the highest number of heartbeats per minute during maximum physical exertion. HRmax is used to determine exercise intensity.
HRmax may vary to some extent according to sport genre, for example running HRmax > cycling HRmax > swimming HRmax.
The most accurate method for determining individual HRmax is to perform a maximal exercise stress test in a laboratory. HRmax can also
be deduced from the HRmax-p score given by the Polar Fitness Test. Or, calculate an estimate of HRmax with the age-based formula
‘220 minus age’.
2. HRsit (Heart rate value in a sitting position)
HRsit is your typical heart rate when you are not doing any physical activity (while sitting). To easily determine HRsit, wear your transmitter,
sit down and do not engage in any physical activity. After two or three minutes, press OK in Time mode to view your heart rate. This is your
HRsit. For a more precise measurement, repeat the procedure several times and calculate your average.
3. VO2max (Maximal oxygen uptake)
VO2max is your body’s maximum capacity for oxygen consumption during maximum exertion. The most accurate way of determining VO2max
is to perform a maximal stress test in a laboratory.
If you know your exact clinically tested VO2max, select the value from the scroll list. Otherwise, measure a comparable value, OwnIndex,
by taking the Polar Fitness Test. For further instructions, see chapter 4.3 Polar Fitness Test.
