OWNZONE METHODS
Polar Heart Rate Monitor uses multiple methods for
determining your OwnZone. The OwnZone determination
is based on measuring and analysing the heart rate
variability during graded exercise.
If your heart rate exceeds the safety limit during the
determination, Polar Heart Rate Monitor picks up your
latest OwnZone definition based on heart rate variability.
Alternatively, if there is no previous determination in
memory, OwnZone limits, which are based on your age
predicted maximum heart rate, will be used. These
methods ensure that the safest possible exercise zone is
determined for you.
The method used in defining the OwnZone is indicated
after the two beeps as follows:
1. OZ.V (OwnZone Variability) and the currently
determined OwnZone limits appear on the
illuminated display.
2. OZ.L (OwnZone Latest) and your previously
determined OwnZone limits appear on the
illuminated display.
3. OZ.A (OwnZone Age) and your age-predicted
heart rate limits appear on the illuminated display.
In models M51 and M52 you will also see which OwnZone
level you have selected to use:
BASIC (OwnZone Basic for allround exercising)
HIGH (OwnZone High for exercising at moderate intensity)
LOW (OwnZone Low for exercising at light to moderate
intensity)
HOW TO USE PREVIOUSLY
DETERMINED OWNZONE
Every time you start the stopwatch and have the OwnZone
option on, the Polar Heart Rate Monitor starts finding your
OwnZone. You can determine your OwnZone for every
exercise session separately. At least it should always be
performed when changing exercise environment, exercise
mode or if you have abnormal feelings about your
physiological state when starting the exercise.
However, you can choose to exercise with the latest
OwnZone limits in case you are not willing to start the
process of redefining your OwnZone.
1. Start the heart rate measurement and stopwatch as
usual.
OZ
appears on the display.
2. Press START/STOP/OK. Polar Heart Rate Monitor starts
using your latest determined OwnZone.
OZ.L and the values for your previously determined
OwnZone appear momentarily on the illuminated
display.
In case there is no previously determined OwnZone in
memory, Polar Heart Rate Monitor starts using your age
predicted exercising limits.
OZ.A and your age-predicted heart rate limits
appear on the illuminated display.
