automatic maximum heart rate

Hello all,

However, my forerunner drops the maximum heart rate again and again by itself on 213 bpm. On my forerunner 955 solar I switched off the automatic maximum heart rate.

So the heart rate zones are wrong and I don't know, if this affects the training intensity, recovery time, etc.

Does anyone know this issue? Can anyone help me pls?

regards, Tobi

Hi Tobi - are you sure your max HR should be over 213? Are you 17 Yo? Have you done a field test with a higher number?

Net net: reset your HR zones after a new auto-detection.

I know this is surprising to many, but no training metric is using time spent in heart rate zones as the basis. Heart rate zones are only for the user to design and execute workouts targeting certain energy pathways and load.

The key to accurate metrics are: (a) accurate Max HR value, (b) accurate rest HR (wear the watch 24/7 and use average rest HR), (c) accurate HR data during exercise (wear a chest strap), (d) accurate pace (running) or power (cycling), (e) expose the watch to a range of efforts from easy to maximal.

Oh sorry, no, I'm 30 and I think, 213 is too high.. I never made an test for the maximum hr, but I think, it is round 200

Okay thank you, I will take a look on it

Thanks for the description. So the max HR value should be entered correctly, that I get correct results. I think, the automatic hr is too high, so I disabled the auto-detection. But my watch set the auto-hr again and again on 213 bpm.

Do you mean that the watch gives you new auto-detections despite having disabled them in settings, or that the watch overrides your Max HR after you change it manually?
