Issues with V02 Max registration Suunto 9

freeheeler

@Saketo-Nemo
you mean if I go for shorter runs the values should be different?
I sometimes suspect that VO2max is dropping while PTE goes towards and beyond 5… but did not verify that yet

@TELE-HO do some intervals, or some half hour runs with some sprints.

Saketo Nemo

@TELE-HO
no, I didn’t want to lead you to short races … but just to run
Sport where in my opinion the value is closer to the truth

@isazi
thanks guys, I’ll try that.
Maybe this makes me younger

Of course it’s an algorythm calculating the fitness age and not sensors measuring exhale air quality vs HR etc… but it still kept me thinking the past few weeks when my watch told me I was 56 years old.
I know I’m always the slowest uphills when we do our annual way from Airolo over Gotthardo back home… but I’m always slipstreaming my friends home at the end of the day…

I’ll do some running this week to figure this out

I’ve been trying to figure this out as well as my fitness level and fitness age are grossly inaccurate on my Suunto 9. As best as I can determine VO2 max outside the lab is determined off of the heart rate and is related to your weight to give you the value of millilitres per kilogram. A normal male athlete would have a range of 40 to 80 millilitres per kilogram for vo2max. So the only measured metric that Suunto is using is your heart rate, and the heart rate recording is considerably inaccurate off the wrist sensor and marginally better using a heart rate strap. I do a lot of biking and cross-country skiing and I find my heart rate recordings are all over the map. That’s far this data is not been useful to measure any kind of progress with training.

@MoveOrRust I get similar VO2MAX on Garmin and Suunto, and have few reasons to doubt the HR reading with the chest straps I own (although I can spot the errors with the wrist ohr sensors).

MoveOrRust

@isazi , yeah I’m not sure what’s going on, same heart rate strap on my Garmin and I get a different heart rate recording than using my Suunto 9.

@isazi
when I do warmup before physiotherapie I sometimes compare OHR to the cardio machines HR measured on the handlebars and they are pretty similar. I think with the chest strap it would be almost equal.
That’s why I think my chest measurements are close to very accurate in any situation.

As far as I know, neither sport is contemplated by Firstbeat in the calculation of Vo2, I think because of too many variables that invalidate the calculation, which is already complex.
talking about “normal” athlete between 40 and 80 seems excessive to me, given that Kilian has 89
Wrist heart rate reading is subjective, but the strap normally works well (yes, when it works: -d)
The data are not only affected by heart rate, but by resting and maximum beats, age and weight.
Also I believe that, sorry if I insist, in the run, at least the flat one, the values are as close as possible to reality as the variables are greatly reduced,

@TELE-HO Firstbeat algorithms love tempo run and intensity. I think 50 aerobic 30 tempo 20 above zone 4 is what they love.

If you have a heavier in your weight than the medium or you are doing base the VO2max will be lower.

Another example if you do polarized training the algorithms of first beat are useless.

@Saketo-Nemo my HR works fine so thats not the issue. The screen with V02 just looks like it did from
The beginning when I started the watch for the first time, even though I’ve registered a lot of different exercises. Running, power walking, swimming, CrossFit etc…

isazi

@filipsvensson92 you need just running for VO2, the other exercises do not contribute, and walking will provide you VO2MAX levels only after the algorithm is working. Did you have some half a hour or so runs, with effort in different HR zones? Did you setup your zones, or at least max and resting heart rate?

filipsvensson92

@isazi @isazi ok. I’ve been running for 20-30 minutes or so. Only indoor running on a treadmill though. I have set up max HR and reating HR. I haven’t sat up any zones though, can this be the issue?

Saketo Nemo

@filipsvensson92
I think u have to run under gps, not on a tapis

Dimitrios Kanellopoulos

@filipsvensson92 indoors should work

filipsvensson92

@isazi I checked an old running exercise from the log now and there I can se the different intensity zones. I can also se something called “cadence” 78v/min it says.

Saketo Nemo

@Dimitrios-Kanellopoulos
ah !

Dimitrios Kanellopoulos

@filipsvensson92 thas your cadence.

freeheeler

@Saketo-Nemo
I’m surprised, too… but I don’t run indoors anyway

filipsvensson92

@Dimitrios-Kanellopoulos do I have to register many running exercises over a shorter time frame to get V02 registered? When I scroll down to the icon it just says: “hold the middle button down to show further instructions” and when I do that just an overall instruction regarding what V02max really is appears…
