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. Cycling performance measurements require a heart rate monitor and a power meter.
These estimates are provided and supported by Firstbeat. 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.
- Predicted race times
-
Your device uses the VO2 max. estimate and your training history to provide a target race time based on your current state of fitness.
- HRV stress test
-
The heart rate variability (HRV) 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 100, 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.
