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 Analytics
.com/performance-data/running/.
NOTE: The estimates may seem inaccurate at first. The watch requires you to complete a few activities to learn
about your performance.
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: The watch uses the VO2 max. estimate and your training history to provide a target race
time based on your current state of fitness
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
page 23).
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
Lactate threshold: Lactate threshold requires a chest heart rate monitor. Lactate threshold is the point where
your muscles start to rapidly fatigue. Your watch measures your lactate threshold level using heart rate data
and pace (Lactate Threshold,
Power curve (cycling): 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
