Orthostatic heartrate test is a common way of testing state of recovery. Make an own sport mode for this purpose, set GPS OFF, search for HR belt and set recording interval to 1 second. Do this test every morning by creating a six and a half minute log. Follow the result on daily basis and detect problems before it is too late. Your body will react differently depending on the state of recovery, illness or overtraining. Follow your own values to learn how your body works. This is how it works: Lay down and start the log. First 5 minutes is average rest HR while laying down. Then watch beeps. Stand up and wait half a minute until the watch beeps again. Stand still and let the watch measure one minute average HR while standing. The watch beeps and the test is ready. Orthostatic HR is now shown as the difference between the stand up HR and the rest HR.
