What should i do if...
...OwnZone determination only seldom gives me heart rate limits
which are based on heart rate variability (OZ.V)?
1. Check that the elastic strap is snug enough.
2. Make sure that the electrodes of the transmitter are moistened
against your skin.
3. Put on the transmitter 15–20 minutes prior to the start of your
exercise to ensure good adaptation between the electrodes and
your skin.
4. Start the first stage of determining your OwnZone sufficiently
slowly. If you obtain the heart rate limits based on age (OZ.A)
within the first 2 minutes you have raised your heart rate too quickly.
The heart rate reading should not rise over 20 beats/minute from
the starting level. During the first stage you can, for example, put
on your sports clothing.
5. If you reach the OwnZone limits based on age (OZ.A) or the
previously determined OwnZone limits based on your heart rate
variability (OZ.L) only after 5 minutes from starting specification
you have not raised your heart rate sufficiently
rapidly. Raise your heart rate more quickly during the OwnZone
determination.
6. If you have always used walking and running to determine your
OwnZone, walking uphill, cycling or using an ergometer may
work better for you.
7. Stress or heavy mental loading may reduce your heart rate
variability so that the needed point where the heart rate
variability vanishes cannot be measured.
11. FREQUENTLY ASKED QUESTIONS
Relax for 5–10 minutes before exercising by sitting down and
decreasing your heart rate.
8. For a small percentage of people the heart rate variability will
not totally disappear with increasing workload. In this case the
age-predicted limits are the best estimation for the exercising
zone.
...the OwnZone limits based on heart rate variability (OZ.V) vary
considerably?
Heart rate variability reacts sensitively to all changes taking place
in the body and environment. The OZ.V heart rate limits are affected
by, amongst others, your daily state of fitness, the time of OwnZone
determination, the type of exercise and state of mind. The lower
limit of the OZ.V heart rate limits can change for the same person
by as much as 30 beats.
However it is important that the feeling of exercise carried out in
the OwnZone is light or moderate. For example if you raise your
heart rate too rapidly after the first stage, you may get too high
OwnZone heart rate limits. If the OwnZone limits seem to be too
high we recommend that the OwnZone determination is done again.
...there is no heart rate reading (- -)?
1. Check that the electrodes of the transmitter are moistened and
that you are wearing it as instructed.
2. Check that you have kept the transmitter clean.
3. Check that there are no sources of electromagnetic radiation in
the close vicinity of the Polar wrist unit, such as TV sets, mobile
phones, CRT monitors etc.
