Turning Off the Wrist-based Heart Rate Monitor
The default value for the Wrist Heart Rate setting is Auto. The watch automatically uses the wrist-based heart
rate monitor unless you pair a compatible heart rate monitor with ANT+ or Bluetooth technology to the watch.
NOTE: Disabling the wrist-based heart rate monitor also disables the wrist-based pulse oximeter sensor. You
can perform a manual reading from the pulse oximeter widget.
1 From the heart rate widget, hold MENU.
2 Select Heart Rate Options > Status > Off.
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
™
. For more information, go to garmin.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 (About VO2 Max. Estimates, page39).
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, page41).
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,
page43).
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 (Performance Condition, page44).
Functional threshold power (FTP): The watch uses your user profile information from the initial setup to
estimate your FTP. For a more accurate rating, you can conduct a guided test (Getting Your FTP Estimate,
page45).
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, page44).
Turning Off Performance Notifications
Some performance notifications appear upon completion of your activity. Some performance notifications
appear during an activity or when you achieve a new performance measurement, such as a new VO2 max.
estimate. You can turn off the performance condition feature to avoid some of these notifications.
1 Hold MENU.
2 Select Physiological Metrics > Perf. Condition.
Detecting Performance Measurements Automatically
The Auto Detection feature is turned on by default. The device can automatically detect your maximum heart
rate and lactate threshold during an activity. When paired with a compatible power meter, the device can
automatically detect your functional threshold power (FTP) during an activity.
1 Hold MENU.
2 Select Physiological Metrics > Auto Detection.
3 Select an option.
