Performance Measurements
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 Analytics™. For more information, go to www.garmin.com/performance-data/running/.
- 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 (About VO2 Max. Estimates).
- Predicted race times
-
The watch uses the VO2 max. estimate and your training history to provide a target race time based on your current state of fitness (Viewing Your Predicted Race Times).
- HRV status
-
The watch analyzes your wrist heart rate readings while you are sleeping to determine your heart rate variability (HRV) status based on your personal, long-term HRV averages (Heart Rate Variability Status).
