HR
Heart Rate
Heart rate is a measurement of the number of times your heart beats
in a minute (BPM).
Sensor
The sensor for heart rate is the chest strap. The chest strap must be ANT+
compatible and correctly located on your chest (Figure 30) and against your
skin. To keep the chest strap in position, it should fit snugly. Slide the buckles to
adjust the length of the strap. The sensors of the chest strap will work better if
the contact area is slightly moist.
Heart Rate Zones
The NODE measures the length of time you spend in each of five heart rate
zones. This is part of the Trip data. The current zone is the number displayed
under the “HR” on the display.
Each heart rate zone from 1 to 5 is based on your maximum heart rate setting
(Table 1). As an example, if you set your maximum heart rate at 160 BPM, Zone
5 would be 90 to 100% of 160 BPM, or 144-160.
Zone 1 would then be 50 to 60%, or 80-96.
To set your maximum heart rate, see page 35.
