These performance measurements are estimates that can help you track and understand your training activities and race performances. The measurements require a few activities using wrist-based heart rate or a compatible chest heart rate monitor.
These estimates are provided and supported by Firstbeat. For more information, go to www.garmin.com/runningscience.
- 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. Your device adjusts the VO2 max. values for heat and altitude, such as when you are acclimating to high heat environments or high altitude.
- 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 your training history, your 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.
- 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.
