indication of incomplete recovery or, for example, a flu that is about to
break out, suggesting that you should lighten your exercise that day.
States of mind such as anxiety, oppression, tension or anger typically
increase heart rate and decrease its variation. A high degree of
concentration also has the same effect.
In order to find your own natural Relaxation Rate, check it for example
right after you wake up on three consecutive mornings after a suffi-
cent amount of sleep. Then compare these normal values of your
Relaxation Rate to situations when you are tired, stressed, when you
have a flu, or when you have not slept well. Note also that heart rate
variation decreases with the years.
In conscious relaxation training, such as meditation and breathing
exercises, you can lower your heart rate and increase its variation. For
example, try the following breathing exercise: sit down, close your
eyes and let your mind relax. Breathe deeply in a peaceful manner
approximately six times in one minute. Open your eyes and check the
effect of the exercise from the wrist receiver display.
The Polar Vantage NV Heart Rate Monitor helps you recognize
stressful situations and makes it easier for you to deal with the sour-
ces of stress. The better you are familiar with the sources of stress, the
better you may eliminate their negative effect and the more relaxed
you are.
RR: R-R-recording indicates the heart rate variability and measures
the time in milliseconds between two successive heart beats. R-R-
recording is suitable for measuring heart rate variability in non-
exercise and at resting situations. We recommed using Contact Gel
(ECG gel) to ensure good contact between your skin and the Trans-
mitter. We also suggest to minimize the use of the following Vantage
NV receiver functions: lap times, timers and backlight to avoid
disturbance during R-R-recording. However, if you decide to make an
R-R-recording during exercise, we recommed you to do it on a
bicycle. Use the Polar Bike Mount to attach the Receiver to the handle-
bar of your bike.
SET: Set mode.
SPLIT TIME: A part of an exercise period
TARGET ZONE: An area between upper and lower target zone limits.
Target zone selection is based on individual's personal fitness goals.

TARGET ZONE LIMITS: Target zone limits are determined as per-
centages of maximum heart rate. The percentages are converted into
the heart rate in beats per minute.
TC: Transmission code.
TIME: Time of Day display
TIMER 1 AND 2: Timer-function helps you to divide your exercise
session into separate phases (e.g. warm-up, exercise phase, cool
down). Timers can be programmed to alarm for example at two minute
intervals.
TRAINING THRESHOLDS: Training thresholds are very individual
and can be determined accurately in the laboratory tests. See Lower
threshold, Upper threshold
TZ: During exercise, in MEASURE mode the symbol indicates that you
are exercising within the Target Zone. In FILE mode indicates the time
spent within the Target Zone.
TZ: During exercise in MEASURE mode indicates that the heart rate
is above the Target Zone. In FILE mode indicates the time spent above
the Target Zone.
TZ: During exercise in MEASURE mode indicates that the heart rate
is below the Target Zone. In FILE mode indicates the time spent
below the Target Zone.
UPPER THRESHOLD; AT, LT, OBLA: Physiological point during
exercise of increasing intensity at which the blood lactate continues
to accumulate so that body is not able to synthetize it, i.e. muscles
require more oxygen than can be transported. This is known as
Anaerobic Threshold (AT), Lactate Threshold (LT) or Onset of Blood
Lactate Accumulation (OBLA) and corresponds usually to 4 mMol
lactate per liter of blood.
YEAR: Shows the year in TIME mode.
