Your device uses the VO2 max. estimate (
) and your training history to provide a
target race time. The device analyzes several weeks of your
training data to refine the race time estimates.
TIP:
If you have more than one Garmin device, you can
enable the Physio TrueUp™ feature, which allows your
device to sync activities, history, and data from other
devices (

About Training Effect
Training Effect measures the impact of an activity on your
aerobic and anaerobic fitness. Training Effect accumulates
during the activity. As the activity progresses, the Training
Effect value increases.
Training Effect is determined by your user profile
information and training history, and heart rate, duration, and
intensity of your activity. There are seven different Training
Effect labels to describe the primary benefit of your activity.
Each label is color coded and corresponds to your training
load focus (
). Each feedback
phrase, for example, “Highly Impacting VO2 Max.” has a
corresponding description in your Garmin Connect activity
details.
Aerobic Training Effect uses your heart rate to measure how
the accumulated intensity of an exercise affects your aerobic
fitness and indicates if the workout had a maintaining or
improving effect on
your fitness level. Your excess post-exercise oxygen
consumption (EPOC) accumulated during exercise is
mapped to a range of values that account for your fitness
level and training habits. Steady workouts at
moderate effort or workouts involving longer intervals (>180
sec) have a positive impact on your aerobic metabolism and
result in an improved aerobic Training
Effect.
Anaerobic Training Effect uses heart rate and speed (or
power) to determine how a workout affects your ability to
perform at very high intensity. You receive a value based
on the anaerobic contribution to EPOC and the type of
activity. Repeated high- intensity
intervals of 10 to 120 seconds have a highly beneficial impact
on your anaerobic capability and result in an improved
anaerobic Training Effect.
You can add Aerobic Training Effect and Anaerobic
Training Effect as data fields to one of your training
screens to monitor your numbers throughout the activity.

Heart Rate Variability and Stress Level
Stress level is the result of a three-minute test performed
while standing still, where the fēnix device analyzes heart rate
variability to determine your overall stress. Training, sleep,
nutrition, and general life stress all impact how a runner
performs. The stress level range is from 1 to 100, where 1 is
a very low stress state and 100 is a very high stress state.
Knowing your stress level can help you decide if your body is
ready for a tough training run or yoga.
Viewing Your Heart Rate Variability and Stress Level
This feature requires a Garmin chest heart rate monitor.
Before you can view your heart rate variability (HRV) stress
level, you must put on a heart rate monitor and pair it with
your device (
Pairing Your Wireless Sensors, page 47
TIP:
Garmin recommends that you measure your stress
level at approximately the same time and under the same
conditions every day.
