The impact of heart rate monitoring
             The physical power of the human body can be divided into three main parts. Endurance, force and speed. Basicly endurance is the most important factor because a long or high intensity training is only possible with a high developed endurance. When you start training, your heart rate increases rapidly in proportion to the intensity of the training. Therefore the heart rate is an accurate sign of intensity of every phsical activity. When you go on with endurance training for a longer periode of time, a decreasing heart rate is one of the positive effects that occur.Your heart works more efficient. As you get fit, your heart is able to pump more blood with every beat. As a result, your heart doesn't have to beat as often to get the oxygen to your muscles.
             During the training the heart rate should be between 60 and 80 percent of your maximum heart rate.Although there are some formula which help us to find the specific heart rate for the training, (like 0,6 * 220-age) we shouldn't forget that this information can't make us keeping the same heart rate during a long workout. Thats why the need of a new technology came up soon.In the 1970s POLAR invented the first accurate wireless heart rate monitor. At that time it was used for the finnish national ski team. From their first launch in 1982, Polar Heart Rate Monitors have became very popular all over the world. POLAR has brought the positive effects of high tech biofeedback training to almost everyone.
             Today, Polar Heart Rate Monitors are found in many sporting events, as well as in gyms, fitness centers and sports training centers. So, how does it work?
             As I mentioned before, your heart rate increases in proportion to the intensity of the training. In Polar Heart Rate Monitors, the transmitter belt detects the electrocardiogram (the electric signal originating from your heart) and sends an electromagnetic signal to the Polar wrist...
