Results
The contact heart rate (CHR) system lets you monitor your heart
rate without wearing a strap.
Gently grasp the contact heart rate pads as shown.
When the system detects your hands, the Heart Rate label will
start flashing in time with your heart beat. During this time, the
system is analyzing and locking in your heart rate. Within about 15
seconds, your digital heart rate in beats per minute (bpm) should
be displayed.
Important: The CHR System should only be used at speeds of 4
mph or lower. Above this speed the CHR accuracy is unavoidably
unreliable due to large muscle movements.
1. Exercise with smooth body
motions.
2. Breathe smoothly and regularly,
and avoid talking. (Talking will
cause unrepresentative heart rate
spikes of 5 to 10 bpm.)
3. Grip the pads lightly, not tightly.
4. Make sure your hands are clean,
free of both dirt and hand lotions.
5. See Appendix A for more details on
Contact Heart Rate monitoring.
When using a Heart Rate Control workout, it is best to use chest
strap monitoring. These workouts work best with the extra
accuracy gained from a chest-contact heart rate monitoring
system.
A Note on CHR Accuracy
CHR monitoring may be a
bit less accurate than a chest
strap, since the heart rate
signals are much stronger at
the chest.
About 5% of the population
cannot be picked up by any
CHR system. This is because
their heart is positioned in a
more up-and-down manner
in their chest, as opposed to
leaning over to one side.
