Getting to Know Fluid Loss
When exercising, your body regulates temperature through sweat loss,
heat radiation and respiration. Dehydration reduces maximal aerobic
power and endurance performance. Greater dehydration results with
greater decrements in performance. The Fluid Check
TM
feature provides
feedback to you with respect to your dehydration level. See page 88 for
Fluid Check
TM
Monitoring Tips and Guidelines.
Fluid Check
TM
feature is controlled by the stopwatch. If you have turned
on the Fluid Check
TM
feature, the watch will show the fluid loss value in
the Recall Data Mode. When in the Chrono Mode, the watch display will
flash and the watch will beep each time your fluid loss equals .5% of your
body weight. The higher the amount of fluid loss, the faster it will beep.
Tips:
1) If you did the Personal MET Calibration ( Optional ) and take the Transmitter Belt
with you during exercise, the watch will calculate the amount of your fluid loss
by detecting the physiological changes of your body ( see page 37 ) .
2) If you have no Transmitter Belt (or forgot take it with you), you would need
to manually input Exercise Type & Intensity (see page 35).
Note: Unless the stopwatch is running, the Fluid Check
TM
feature will
automatically turn off at the midnight (i.e. 12:00 PM).
