Heart Rate Features

You can watch the color gauge or data field during your run or view the summary on your Garmin Connect account after
your run. As with the other running dynamics data, ground contact time balance is a quantitative measurement to help you
learn about your running form.
Vertical Oscillation and Vertical Ratio Data
The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and whether it is
positioned at the chest (HRM-Tri or HRM-Run accessories) or at the waist (Running Dynamics Pod accessory).

Tips for Missing Running Dynamics Data
If running dynamics data does not appear, you can try these
tips.
Make sure you have a running dynamics accessory, such
as the HRM-Pro accessory.
Accessories with running dynamics have on the front
of the module.
Pair the running dynamics accessory with your
Forerunner device again, according to the
instructions.
If you are using the HRM-Pro accessory, pair it with your
Forerunner device using ANT+ technology, rather than
Bluetooth technology.
If the running dynamics data display shows only zeros,
make sure the accessory is worn right-side up.
NOTE:
Ground contact time and balance appears only
while running. It is not calculated while walking.
Performance Measurements
These performance measurements are estimates that can
help you track and understand your training activities and
race performances. The measurements require a few
activities using wrist-based heart rate or a compatible chest
heart rate monitor. Cycling performance measurements
require a heart rate monitor and a power meter.
These estimates are provided and supported by Firstbeat.

NOTE:
The estimates may seem inaccurate at first. The
device requires you to complete a few activities to learn
about your performance.
VO2 max
�
:
VO2 max. is the maximum volume of oxygen
(in milliliters) you can consume per minute per kilogram
of body weight at your maximum performance.
Predicted race times:
Your device uses the VO2 max.
estimate and your training history to provide a
target race time based on your current state of
fitness.
HRV stress test:
The heart rate variability (HRV) stress test
requires a Garmin chest heart rate monitor.
The device records your heart rate variability while
standing still for 3 minutes. It provides your overall
stress level. The scale is 1 to 100, and a lower score
indicates a lower stress level.
Performance condition:
Your performance condition is a
real- time assessment after 6 to 20 minutes of activity. It
can be added as a data field so you can
view your performance condition during the rest of your
activity. It compares your real-time condition to your
average fitness level.
Functional threshold power (FTP):
The device uses your
user profile information from the initial setup to
estimate your FTP. For a more accurate rating, you can
conduct a guided test.
Lactate threshold:
Lactate threshold requires a chest heart
rate monitor. Lactate threshold is the point where your
muscles start to rapidly fatigue. Your device measures
your lactate threshold level using heart rate data and
pace.
Turning Off Performance Notifications
Some
performance notifications appear upon completion of
your activity. Some performance
notifications appear during an activity or when you
achieve a new performance measurement, such as a
new VO2 max. estimate. You can turn off the
performance condition feature to avoid some of these notifications.

The Auto Detection feature is turned on by default. The
device can automatically detect your maximum heart rate,
and lactate threshold during an activity. When paired with a
compatible power meter, the device can
