Before beginning a regular exercise program consult
your doctor
• if you are over 40 years of age and have not been
following a regular exercise program during the past 5
years
• 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.
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.
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 decreasing your heart rate.
8. For a small percentage of people the heart rate
variability will not totally disappear with increasing
