Suunto 9 Peak heart rate plateau

iocast · 15 Sept 2021, 09:29

Hi,

today i tried to reach my hr limit. i noticed that there is a plateau at 210 bpm. is this normal?
The watch, the suunto app and the fit-file, all shows me a heart rate plateau of 210 bpm over more than 2 minutes. I can’t believe that this is correct.

does anyone have the same experience?

Best regards

Go to watch Settings - General - Personal and check your Max HR you set there. Isn’t it 210 by any chance?

Do you use a HR belt or the OHR ?

@inkognito thank you for your reply.
I tried this a few days ago. then I always run in zone 1 on over 90% of my runs.
the maximum measured and recorded heart rate should be independent of the settings and the zones.
the funny thing is that i never get above 210 on many runs no matter what I set and how i put the watch on (instructions on suunto.com already followed)

@theguyfromthesummit ohr, the one built into the watch. I don’t use any additional equipment.

@iocast I will ask Suunto if this is within specs or not. I have no chance of getting such a heart rate until I am having a heart attack so never noticed

@isazi many thanks. If you need the .fit or the samples.json file let me know.

@iocast
Also a good question, do you think 210bpm is something normal for you? It is possible but quite unusual. Is the problem this “plateau” or “bad measurement” stucked at 210bpm?

iocast · 15 Sept 2021, 11:01

@mff73 i knew these questions would come. whether it is healthy or not is another question. i just wonder if the sensor or watch is measuring correctly. over 2 minutes no variations in the measurement can not be correct.

@iocast
If your heart really goes to 210, you should know , and healthy or not depends on other factors. If you have no HR belt to check, there is still the old manual pulse “measurment” finger on your inner wrist or carotide, count over 10s and multiply by 6.
But plateau is not really normal, whatever the value.

@iocast so the question if there is a hard limit of 210 in the watch or app has been forwarded to Suunto and reached the developers, will hopefully get an answer for you.

My maximum heart rate after a running test is 208, so 210 is no surprise to me.

@iocast If you look at your training over 6 months or more, especially with a HR belt what is your highest HR reading for a 30 sec time period. My only concern is that this is aberrant HR readings. It is possible but your zone 4/5 is set at 162 so over 200 seems very high for max HR.

@iocast app wise we have a hard limit on the zone 5 (view only) and I think export wise as well. If you have a Suunto app link for me I can get the raw data and see if they were clipped.

@dimitrios-kanellopoulos I sent you a pm. what do you mean with suunto app link. (sorry. I am not yet familiar with the jargon. this is my first suunto watch.)

That’s a massive ceiling you have there! I only know one person that has a max above me and mine is only 194bpm… however I am 44 so not exactly a spring chicken

When I was in my early to mid 40s my max was in the low 190s. Twenty years later my max now is ~180. However, max HR has more to do with genetics than anything else and it is used to set training zones along with an anaerobic threshold and a aerobic threshold.

I don’t think plateau HR is something normal so there should be a limit or an error:

getting the measurements
threshold in the sensor
threshold in SA

Said that, 210??? really?

205 for me on FTP test, but some years ago I got 200 + (check here, with ambit 2 and suunto hr belt new at the time)
