Recalibrating Training Status after changing MaxHR

Former Member over 6 years ago

I have recently discovered that my max HR has been set ridiculously high for the last few month. I had set it to my correct max HR about a year ago following a run fitness test, but somewhere along the way it had been set to 202 and not the 189 that I had entered. I have changed the Max HR back down to 189 and now all my training status's, Vo2Max etc. are all out of whack.

Question 1: Does anybody know how my MaxHR could have changed? I could have entered it wrong but i can't see how I could have entered 202 by mistake.

Question 2: I think it's been months using the wrong MaxHR and so I'm not sure that the data the watch has is even remotely accurate. So should I simply reset and start getting new metrics again or will it catchup at some point? I have gone from barely being able to keep the training status out of recovery, to now massively overreaching with all my runs have being unproductive for weeks now.

1\I assume you had the default setting of 'auto detect Max HR' and subsequently recorded an activity with a rogue HR. You can order the activity list by MaxHR to identify it. I suggest that you complete a MaxHR test.

In addition to TrippyZ's suggestion of the possibility of autodetect and an erroneous measurement, it is a common problem that the watch can import incorrect HR zones after a firmware update - especially if you are using the LTHR method to calculate zones. If you do make a change to your maxHR, make sure it is in Garmin Connect (preferrably the web version rather than the mobile app), as otherwise the incorrect number can be re-imported.

The VO2Max readings (and therefore TS, etc) should stabilize with the correct HR numbers - a couple of weeks data (especially if you are running multiple times per week) should be enough to stabilize readings. I'd suggest taking a look at Performance Condition graphs for recent runs to confirm this - generally PC should start positive, and gradually decline as fatigue accumulates over the course of a run. I also assume you are road running, and not transitioning to trail running as spring weather impoves?

Thank you both for your feedback.I have taken a look at all my old data and indeed there is a Max HR of 202 in there, although it was years ago, but I do suspect that was where it came from. I tend to run everyday, on the road, and I am starting to see it settle down now. All runs are still Unproductive as I am assuming that it's still catching up but hopefully soon I'll get my first Productive soon.
