Performance Measurements - Garmin DESCENT MK1 Owner's Manual

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
/physio.
NOTE: The estimates may seem inaccurate at first. The device requires you to complete a few activities to
learn about your performance.
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.
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 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.
HRV stress test: The HRV (heart rate variability) 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.
