OPTIONS: Indicates the Options
mode.
OwnCal: Calculates energy
expenditure during exercise in
kilocalories. 1 kilocalorie (kcal) = 1000
calories (cal). You can follow how
much energy you loose by exercising
in one exercise session or in a day,
week or even a year. The OwnCal can
be used as a dose measure of exercise
e.g. in nutrition planning. OwnCal
calorie calculation starts when your
heart rate reaches 90 bpm or is above
60% of your maximum heart rate,
whichever is smaller. These limits are
set to count only exercise calories.
The higher the heart rate, the faster
the energy expenditure. OwnCal is
individually calibrated by your preset
weight, maximal oxygen uptake
(VO
2max
) and maximum heart rate
(HR
max
). The most accurate OwnCal is
received by entering your clinically
measured (in maximal treadmill or
bicycle stress test) VO
2max
and HR
max
into the wrist receiver. Energy
expenditure measurement is most
accurate in continuous activities such
as cycling and running.
OwnINDEX: Result of Polar Fitness
Test and comparable score with
maximal oxygen uptake (VO
2max
) in
ml/kg/min.
PI %, Pedalling index*: Helps you
to analyse how evenly the power is
distributed. The smoother the
pedalling motion, the closer the
figure is to the ideal 100 %.
A pedalling index of 100 % means
that power is applied evenly
throughout the whole pedal
revolution.
Pwr*: Indicates Power Output
measurement in cycling.
RecoDist, distance-based
recovery: You set the recovery
distance in the Options mode. In the
File mode, you will see the drop in
your heart rate and the recovery
distance.
RecoHr, heart-rate-based
recovery: You set the heart rate,
*Optional Polar Cadence Sensor or Polar Power Output Sensor required.
