POLAR GLOSSARY
Coded heart rate transmission: Polar T61™ transmitter
automatically locks in a code to transmit your heart rate to
your wrist receiver. In coded transmission the receiver
accepts heart rate from your transmitter only. Coding
significantly reduces crosstalk caused by other users of
heart rate monitors. However, it does not necessarily
reduce all environmental interference.
Electrodes: The grooved areas of the transmitter, against
the skin. Pick up the heart's electrical impulses.
Heart rate: The number of heart beats per minute (bpm)
Heart rate variability: Fluctuations of interbeat intervals.
Heart rate variability of a healthy subject is in general large
in resting conditions and during light exercise. Heart rate
variability gradually disappears when exercise becomes
more intense and heart rate increases.
Target zone, TZ: The area between the upper and lower
target zone limits. Can be defined automatically by Polar
heart rate monitor or manually by yourself.
