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.
