NOTE: The estimates may seem inaccurate at first. The
device requires you to complete a few activities to learn
about your performance.
Training status : Training status shows you how your
training affects your fitness and performance. Your
training status is based on changes to your training
load and VO2 max. over an extended time period.
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.
Recovery time : The recovery time displays how much
time remains before you are fully recovered and
ready for the next hard workout.
Training load : Training load is the sum of your excess
post- exercise oxygen consumption (EPOC) over the
last 7 days. EPOC is an estimate of how much energy
it takes for your body to recover after exercise.
Predicted race times : Your device uses the VO2 max.
estimate and published data sources to provide
a target race time based on your current state of
fitness. This projection also presumes you have
completed the proper training for the race.
HRV stress test : The HRV (heart rate variability) 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
1 00, 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 On Performance Notifications
Performance notifications are alerts that appear
upon completion of your activity. You can turn on
notifications for performance measurements, such as
your performance condition and recovery time. Some
performance notifications appear when you achieve
a new performance measurement, such as a new VO2
max. estimate.

Automatically Detecting Performance
Measurements
You can enable the device to automatically detect your
maximum heart rate, lactate threshold, and functional
threshold power (FTP) during an activity.

your fitness level and performance. Your training status

over an extended time
period. You can use you your training status to help
plan future training and continue improving your
fitness level.
No status : The device needs one or two weeks of
training history, including activities with VO2 max.
results from running or cycling, to determine your
training status.
Detraining : Detraining occurs when you are training
much less than usual for a week or more, and it is
affecting your fitness level. You can try increasing
your training load to see improvement.
Recovery : Your lighter training load is allowing your
body to recover, which is essential during extended
periods of hard training. You can return to a higher
training load when you feel ready.
Maintaining : Your current training load is enough to
maintain your fitness level. To see improvement, try
adding more variety to your workouts or increasing
your training volume.
Productive : Your current training load is moving your
fitness level and performance in the right direction.
It is important to plan recovery periods into your
training to maintain your fitness level.
Peaking : Peaking means that you are in ideal race
condition.
Y our recently reduced training load is allowing your
body to recover and fully compensate for earlier
training. You should plan ahead, since this peak state
can only be maintained for a short time.
Overreaching : Your training load is very high and
counterproductive. Your body needs a rest. You
should give yourself time to recover by adding
lighter training to your schedule.
Unproductive : Your training load is at a good level,
but your fitness is decreasing. Your body may be
struggling to
