8.2MINIMIZING POSSIBLE RISKS WHEN EXERCISING
Exercise may include some risk, especially for those who have been sedentary. Before starting a regular exercise program, it is recommended that you answer the following questions about your health status. If the answer is yes to any of these questions,
we recommend that you consult a doctor before starting an exercise program.
•Have you been physically inactive for the past 5 years?
•Do you have high blood pressure?
•Do you have 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, medications for heart problems, blood pressure, psychical conditions, asthma and breathing, as well as some energy drinks, alcohol, and nicotine, can affect heart rate.
It is important to be sensitive to your body’s reactions during exercise. If you feel unexpected pain or excessive fatigue when exercising, it is recommended that you stop the exercise or continue at a lighter intensity.
Notice to persons with pacemakers, defibrillators, or other implanted electronic devices. Individuals who have a pacemaker use the Polar heart rate monitor at their own risk. Before use, we always recommend an exercise test under a doctor’s supervision. The test is to ensure the safety and reliability of the simultaneous use of the pacemaker and the heart rate monitor.
If you are allergic to any substance that comes into contact with your skin or if you suspect an allergic reaction due to using the product, check the listed materials in the Technical Specifications chapter on page 52.
