Does VO2 Max/Performance condition take into account elevation change and heat?

I'm assuming it may take into account the elevation.

I'm pretty sure it doesn't take into account the outside temperature though.

Just curious if take either. Sucks a little to see it telling you you're sucking it up but I also try not to listen too much :) and focus on the overall trend. But you know how it goes.

I read a document from firstbeat site about Vo2max calculation. If I understood well their algorithm take into account if you are running up and down on hills; I don't think the same about temperature

im running in 40 Celsius and up... it is probably bit different than up North where temps are so much lower. Good question how this effects your running?

It makes it suck :). Relatively speaking of course. And the watch tells me I'm unproductive :). I don't sweat it too much, but you know we all listen to these stupid watches too much.

Thanks Morrison. That's pretty much what I figured.

Pretty sure it doesn't factor in the temperature.

Last week I had a race and the temperature was in the 50s so I did really well (plus since it was a race I was going harder than I would for a regular training run). After that my V02 max jumped from the 51 (where it had been steady the previous month) all the way up to 58. Now the temperatures are in the 80s and 90s, my V02 max drops 1 or 2 points every time I run and my Garmin is telling me I'm unproductive. ¯\_(ツ)_/¯

While it would be nice for temperature to be taken into account to show your "absolute" VO2Max, at the end of the day you want your VO2Max/Predicted Times to be in line with the current temperature and if it's hot well you won't be beating your PR !

Really? That's unsustainable for any length of time...apparently Would be interested to know how long and how hard you can manage to run in those temperatures. Any chance you could share some of those activities. I'm an exercise physiologist and would be interested to see them. I run occasionally in mid to high 30s and that's more than enough for me.

Humidity will play a big part in how well and long you can run at a given temp. We're hitting high 80's-low 90's right now with ~70% in Maryland and it's stifling, but when I was growing up in So California we used to have track practice in the low 90's with 40%-50% humidity and while it was hot it wasn't oppressive.

Then again I was 18 then and 53 now so that could be affecting my perspective too. ;)

Not sure I agree, Garmin should not call it 'VO2 max' without controlling for temperature/humidity, rather something like 'fitness indicator' or something.

I can live with climate bias, it's the day-to-day changes that screw up the metrics. When the weather goes from fresh to hot my trainings become unproductive and VO2 max drops by 1 or 2.

Apologies, should be 30 and up. Im able to run around 6km. When humidity is high then it drops to 5km or 4km.
Here is one of my runs: https://connect.garmin.com/modern/activity/1704653342 and another: https://connect.garmin.com/modern/activity/1787054459. Im not a runner, I just do it for general fitness and to loose few kgs for climbing.

Weird i replied to this and it didnt show up.... anyway apologies it should be 30c and up... I usually run 6km but when humidity is higher I manage 4 maybe 5km. here some of my runs: https://connect.garmin.com/modern/activity/1781751963 and another: https://connect.garmin.com/modern/activity/1787054459. Im not a runner, i do this to loose some kgs for climbing. Anyway it would be cool to see how weather effects your performance.
