M. POLAR GLOSSARY

Activity level: Your long-term
physical activity level you need to
assess in order to do the Polar Fitness
Test.
Altitude and temperature: The
altitude and temperature are
measured by using an atmospheric
pressure sensor. Air pressure changes
constantly due to various weather
conditions and therefore the
calculated altitude of a certain spot
may differ. Variation of high and low
pressure or air conditioning can cause
a change in the altitude reading.
For example, a thunderstorm can
cause a change of up to 80 mbars,
which means a change of
approximately 700 m/ 2000 ft in the
calculated altitude. Therefore, it is
recommended that you adjust the
exact starting point altitude whenever
a reliable reference; for example, a
peak pointer or a map, is available. It
is also recommended that you check
the altitude of your house and other
common starting points for training.
Coded heart rate transmission:
Polar T61 Transmitter automatically
locks in a code to transmit your
heart rate to the wrist receiver. In a
coded transmission the receiver
accepts heart rate data only from
the Polar T61 Transmitter. 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 rate.
Maximal oxygen uptake:
(maximal aerobic power, VO
2max
) Is
the maximal rate at which oxygen
can be used by the body during
maximal work. VO
2max
is a good
index of aerobic fitness.
Maximum heart rate: (HR
max
) Is
the highest number of heart beats
per minute of a person.
Target heart rate zone: The area
between the upper and lower
target heart rate limits. Target zone
selection is based on personal
fitness goals.
