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 Garmin Human Performance Lab™. For more information, go to www.garmin.com/garmin-technology/cycling-science.

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.

Recovery time

The recovery time displays how much time remains before you are fully recovered and ready for the next hard workout.

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.

Power curve

The power curve displays your sustained power output over time. You can view your power curve for the previous month, three months, or twelve months.
