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 10 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. Relax for 5 -
10 minutes before exercising by sitting down and
• if you smoke
• if you have high blood pressure
• if you have high blood cholesterol
• if you have any signs or symptoms of any disease
• if you are recovering from a serious illness or a medical
treatment e.g. surgery
• if you use a pacemaker or another implanted electronic
device.
Note also that in addition to exercise intensity the heart
rate can be affected by, amongst others, heart, circulation
(particularly high blood pressure) and asthma and other
breathing medications, as well as some energy drinks,
alcohol and nicotine.
It is important to be sensitive to your body’s
reactions during the exercise. If you feel unexpected
pain or tiredness regarding your exercise intensity level, it is
recommended to stop the exercise or continue at a lighter
intensity.
If you are allergic to any substance that comes into
contact with the skin, check the Polar heart rate monitor
materials from the “Technical specifications” chapter. It is
recommended that you wear the transmitter against your
bare skin to ensure flawless operation. However, if you
wish to wear the transmitter over a shirt, moisten the shirt
well under the electrodes.
Notice to persons with pacemakers, defibrillator or
other implanted electronic device. Persons who have a
pacemaker use the Polar heart rate monitor at their own
risk. Before starting use, we always recommend an exercise
test under doctor’s supervision. The test is to ensure the
safety and reliability of the simultaneous use of the
pacemaker and the heart rate monitor.
