14. Indoor running calibration
Once your indoor run is complete, select “Calibrate and Save” while saving the record. If the
watch records a mileage greater than 0.5km, the calibrated mileage will optimize the
algorithm to make the subsequent mileage records more accurate.
If the mileage records are still inaccurate after multiple calibrations, you can select
“Recalibrate”.
Metrics
Amazfit Stratos provides a wealth of physical activity metrics such as VO2 max, training
effect, training load and more.
The score is a great help for your training or exercising. This assessment allows you to see
changes in your performance level as they happen and can help identify affecting factors
along the way. These metrics are based on your personal background information (age, gender,
height, weight, etc.) and heart rate. As your Stratos continually understands and analyzes your
body and activity data, the assessment of your score will be more accurate.
1） VO2max
VO2 max, or maximal oxygen uptake, is a common measurement linked to aerobic
endurance that many athletes use to determine their overall fitness. VO2 max is the
measurement of the maximum volume of oxygen that you can consume during intense, or
maximal exercise. It is measured as milliliters of oxygen used in one minute per kilogram of
body weight (ml/kg/min). It is one factor that may help determine an athlete's capacity to
perform sustained exercise. A high VO2 max is necessary for success in endurance events.
The calculation relies on a combination of personal background information (age, gender,
height, weight, etc.) and data collected during your activity. This includes a focus on heart rate
and running/walking speed. VO2 max varies greatly between individuals.
How to get my VO2 Max?
1) Enter your accurate personal data (age, gender, weight, height) in Amazfit Watch App.
2) Wear your Stratos and run for at least 10 minutes outdoor. Save your run and your heart
rate result should reach 75% of the maximum heart rate you set.
3) View your VOX max in the activity history from your watch or tap “my status” in
Amazfit Watch App to have a look.
The VO2max score corresponds to seven different exercise abilities:
