In the cycling computer, these values are used to calculate your energy expenditure.
Heart Rate: HR
max
, HR
sit
HR
max
(Maximum heart rate): Your age-predicted HR
max
value (220 - age) is used as a default. Set
your HR
max
manually if your maximum heart rate has been determined in a lab, if you have performed
the Fitness test with the Polar CS600X cycling computer, or if you have tested your maximum heart
rate in the field yourself.
HR
sit
(Heart rate value in a sitting position): Your age-predicted HR
sit
value is used as a default. Set
your HR
sit
value if you have determined it according to the instructions. For instructions, see Heart
Rate Value in a Sitting Position in Background Information.
Maximal Oxygen Intake: VO
2max
VO
2max
is your body’s maximum capacity for oxygen consumption during maximum exertion. The most
accurate way of determining VO
2max
is to perform a maximal stress test in a laboratory. If you know
your exact clinically-tested VO
2max
, set the value in the cycling computer. Otherwise, measure a
comparable value, OwnIndex, by taking the Polar Fitness Test™. For further information, see Polar
Fitness Test™.
