3.25.2.1 Quick recovery test
The quick recovery test, powered by Firstbeat, is an alternative way
to measure your recovery status. The sleep recovery test is a more
accurate method to measure your recovery status. But for some
individuals, wearing a heart rate sensor throughout the night may
not be feasible.
The quick recovery test only takes a few minutes. For best results,
you should lie down, stay relaxed, and not move around during the
test.
We recommend performing the test in the morning after waking
up. This helps ensure you get comparable results day to day.
You need to perform three tests while you are feeling well
recovered and have no accumulated recovery time to calibrate the
test algorithm.
The calibration tests do not need to be done in sequence, but they
need to be at least 12 hours apart.
During this calibration period, you may get results that are higher
or lower than expected. These results are indicated in the watch as
your estimated recovery status until the calibration is completed.
To perform a quick recovery test:
1. Put on your heart rate belt and ensure the electrodes are moist.
2. Lie down and relax in a quiet environment free from
disturbances.
3. Press [Start Stop], scroll to RECOVERY with [Start Stop], and
select with [Next].
4. Scroll to Quick test and select with [Next].
