Why Use a Polar
Heart Rate Monitor
By monitoring heart rate, the simple observation
that the harder we exercise, the faster our heart beats is put to good use.
Fitness enthusiasts and professional athletes alike have for decades been
relying on the information provided by their heart rate monitor for the
following reasons:
- A heart rate monitor is the best tool for
maintaining an ideal weight
- A heart rate monitor is like a rev counter,
giving a precise measurement of exercise intensity.
- Training and exercising at your own ideal pace
is made possible with a heart rate monitor.
- Direct measurement of heart rate during
exercise is the most accurate way to gauge performance.
- Progress can be monitored and measured,
increasing motivation.
- It maximizes the benefits of exercise in a
limited amount of time.
- It introduces objective observation. Are you
on the right track? Are you improving?
- It is a tool for regulating frequency and
intensity of workouts.
- Because of the immediate feedback it provides,
heart rate monitoring is an ideal training partner.
How does it work?
When you start training, your heart rate increases
rapidly in proportion to the intensity of the training. In Polar Heart Rate
Monitors, the transmitter belt detects the electrocardiogram (ECG - the
electric signal originating from your heart) and sends an electromagnetic
signal to the Polar wrist receiver where heart rate information appears.
The heart moves blood from the lungs (where the
blood picks up oxygen) to the muscles (which burn the oxygen as fuel) and back
to the lungs again. The harder the training, the more fuel the muscles need and
the harder the heart has to work to pump oxygen-rich blood to the muscles.
As you get fitter, 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 needed oxygen to your muscles, decreasing resting heart rate
and exercise heart rate on all exertion levels. |
