Heart Rate Variability and Stress Level
Stress level is the result of a three-minute test performed while standing still, where the quatix device analyzes
heart rate variability to determine your overall stress. Training, sleep, nutrition, and general life stress all impact
how a runner performs. The stress level range is from 1 to 100, where 1 is a very low stress state and 100 is a
very high stress state. Knowing your stress level can help you decide if your body is ready for a tough training
run or yoga.
Viewing Your Heart Rate Variability and Stress Level
This feature requires a Garmin chest heart rate monitor. Before you can view your heart rate variability (HRV)
stress level, you must put on a heart rate monitor and pair it with your device (
Pairing Your Wireless Sensors,
).
TIP: Garmin recommends that you measure your stress level at approximately the same time and under the
same conditions every day.
1 If necessary, press START, and select Add > HRV Stress to add the stress app to the apps list.
2 Select Yes to add the app to your list of favorites.
3 From the watch face, press START, select HRV Stress, and press START.
4 Stand still, and rest for 3 minutes.
Performance Condition
As you complete your activity, such as running or cycling, the performance condition feature analyzes your pace,
heart rate, and heart rate variability to make a real-time assessment of your ability to perform compared to your
average fitness level. It is approximately your real-time percentage deviation from your baseline VO2 max.
estimate.
Performance condition values range from -20 to +20. After the first 6 to 20 minutes of your activity, the device
displays your performance condition score. For example, a score of +5 means that you are rested, fresh, and
capable of a good run or ride. You can add performance condition as a data field to one of your training screens
to monitor your ability throughout the activity. Performance condition can also be an indicator of fatigue level,
especially at the end of a long training run or ride.
NOTE: The device requires a few runs or rides with a heart rate monitor to get an accurate VO2 max. estimate
and learn about your running or riding ability (
About VO2 Max. Estimates, page 52
).
Viewing Your Performance Condition
This feature requires wrist-based heart rate or a compatible chest heart rate monitor.
1 Add Performance Condition to a data screen (
Customizing the Data Screens, page 31
).
2 Go for a run or ride.
After 6 to 20 minutes, your performance condition appears.
3 Scroll to the data screen to view your performance condition throughout the run or ride.
