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
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 tum off the
performance condition feature to avoid some of these
notifications.

About V02 Max. Estimates
VO2 max. is the maximum volume of oxygen (in milliliters) you
can consume per minute per kilogram of body weight at your
maximum performance. In simple terms, VO2 max. is an
indication of athletic performance and should increase as your
level
of fitness improves. The fenix device requires wrist-based
heart rate or a compatible chest heart rate monitor to display
