Description
Green
Balanced
Your seven-day average HRV is within your baseline range.
Orange Unbalanced Your seven-day average HRV is above or below your baseline range.
Red
Low
Your seven-day average HRV is well below your baseline range.
No color
Poor
No status
Your HRV values are averaging well below the normal range for your age.
No status means that there is insufficient data to generate a seven-day average.

Performance Condition
As you complete your activity, such as running or cycling, the performance condition feature analyzes your pace,
heart rate, and heart rate variability to make a real-time assessment of your ability to perform compared to
your average fitness level. It is approximately your real-time percentage deviation from your baseline VO2 max.
estimate.
Performance condition values range from -20 to +20. After the first 6 to 20 minutes of your activity, the device
displays your performance condition score. For example, a score of +5 means that you are rested, fresh, and
capable of a good run or ride. You can add performance condition as a data field to one of your training screens
to monitor your ability throughout the activity. Performance condition can also be an indicator of fatigue level,
especially at the end of a long training run or ride.
NOTE: The device requires a few runs or rides with a heart rate monitor to get an accurate VO2 max. estimate
and learn about your running or riding ability (
About VO2 Max. Estimates, page 21
).
Viewing Your Performance Condition
This feature requires wrist-based heart rate or a compatible chest heart rate monitor.
1 Add Performance Condition to a data screen (
Customizing the Data Screens, page 85
).
2 Go for a run or ride.
After 6 to 20 minutes, your performance condition appears.
3 Scroll to the data screen to view your performance condition throughout the run or ride.
Lactate Threshold
Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the bloodstream.
In running, this intensity level is estimated in terms of pace, heart rate, or power. When a runner exceeds the
threshold, fatigue starts to increase at an accelerating rate. For experienced runners, the threshold occurs at
approximately 90% of their maximum heart rate and between 10 km and half-marathon race pace. For average
runners, the lactate threshold often occurs well below 90% of maximum heart rate. Knowing your lactate
threshold can help you determine how hard to train or when to push yourself during a race.
If you already know your lactate threshold heart rate value, you can enter it in your user profile settings (
Your Heart Rate Zones, page 69
). You can turn on the Auto Detection feature to automatically record your
lactate threshold during an activity.
