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 57).
