8.2 Minimizing Possible Risks when Exercising
Exercising may include some risk. Before beginning a regular
activity, we recommend that you answer the following questions
concerning your health. If the answer is yes to any of these
questions, we recommend consulting a doctor before starting
any activity.
• Have you been physically inactive for the past 5 years?
• Do you have high blood pressure or high blood cholesterol?
• Do you have symptoms of any disease?
• Are you taking any blood pressure or heart medication?
• Do you have a history of breathing problems?
• Are you recovering from a serious illness or medical
treatment?
• Do you use a pacemaker or another implanted electronic
device?
• Do you smoke?
• Are you pregnant?
Note that in addition to exercise intensity, medication for heart,
blood pressure, psychological conditions, asthma, breathing etc.
as well as some energy drinks, alcohol and nicotine may affect
heart rate.
It is important to be sensitive to your body’s responses during
exercise. If you experience unexpected pain or excessive fatigue
when exercising, it is recommended you stop the exercise or
continue at a lighter intensity.
Notice to individuals with pacemakers, defibrillators or other
implanted electronic devices. Individuals who have a pacemaker
use the Polar heart rate monitor at their own risk. Before starting
use, we always recommend a maximal exercise stress test under
a doctor’s supervision. The test is to ensure the safety and
reliability of the simultaneous use of the pacemaker and the
Polar heart rate monitor.
If you are allergic to any substance that comes into contact with
your skin or you suspect an allergic reaction due to using the
product, check the materials mentioned in chapter 10 Technical
Specifications. To avoid skin reactions to the transmitter,
wear it over a shirt. However, the shirt must be wet under the
electrodes to ensure flawless operation.
Note: The combined impact of moisture and intense abrasion
may cause a black color to come off the transmitter’s surface,
which might stain light-colored clothes especially.
