Swimming Metrics (Pool Swimming) - Polar Electro V800 User Manual

when using GPS when swimming, interference may occur, and the recorded
data is not as accurate as in land activities. GPS may also interfere with
GymLink transmission, causing disturbance in heart rate measurement when
swimming. Therefore it is recommended to switch GPS off when measuring
heart rate in water.
When measuring heart rate in water, you may experience interference
because:
The ECG signal strength is individual and may vary depending on the indi-
l
vidual's tissue composition. Problems occur more frequently when meas-
uring heart rate in water.
Pool water with high chlorine content and seawater are very conductive.
l
Sensor electrodes can short-circuit in these conditions preventing ECG
signal detection.
Jumping into water or strenuous muscle movement during competitive
l
swimming may shift the sensor on your body where ECG signals are not
detected.

Swimming Metrics (Pool Swimming)

Swimming metrics help you analyze each swimming session, and follow your
performance and progress in the long run. The metrics record your swim
distance, time and pace, stroke rate, and also identify your swimming style. In
addition, with the help of the SWOLF score you can improve your swimming
technique.
To get the most accurate information, make sure your have set which hand
you wear V800 on. This can be set in V800 General Settings.
