My take on the VO2 Max readings:
Must use the RUN app on the watch and run for a minimum of 20 minutes, not a 3rd party like Nike Run or Strava. Cycling will not work it must be a run.
You must also go pretty much balls out, after all it is a VO2 MAX reading, you can’t really go for a slow run & expect a max reading.
For everyone having an issue, please try the above and report back.
Thanks

I used the stock Apple workout app, set to outdoor run. I ran for 30 minutes, during which my heart rate regularly exceeded 180 bpm. The problem is that under Data Sources & Access, my Watch isn’t listed, whereas other people’s watches are, and seem to intermittently get VO2 max ratings when the other criteria you specified are fulfilled. I see no way to add my watch as a data source in the first place.
So I think I’ve got a solution. I went on another run and got a VO2 max reading. I matched the time of the reading to my Cardiogram to figure out at what point in my workout it was logged. Now throughout my run I hit 180 bpm multiple times for extended periods and at the end I really exerted myself and it got to that level again. Turns out it was at the end, during my rather strenuous but brief exertion was when VO2 max was logged, even though I hit that same bpm for longer earlier on during my run (these probably didn’t have enough exertion to trigger the reading). I went into VO2 max Data Sources & Access where my Watch was automatically added.
I have the same issue — sort of — I have a first genreation watch and a 6 Plus (everything is up to date). I can see data from a 3 mile run and 3 mile walk but not a 13 mile bike ride I took this morning. It’s odd.
I did a 5k run on Saturday using Apple’s Workout App. VO2 showed up in my Health app.
Did a short hill climb run in Strava yesterday and no VO2 results.
Just completed a 3k run in Nike Run Club and no VO2 max either.
Maybe it’s exclusive to The Workout App
I THINK IN ORDER TO GET VO2 MAX READING YOU HAVE TO ACTUALLY PERFORM THE TASK CLOSE TO YOUR MAXIMUM EFFORT. FOR ME IT SEEMS TO ONLY WORK WHEN I DO A WORKOUT AND MY HEART SPENDS A DECENT AMOUNT OF TIME OVER 185BPM
Yes, I’m aware it works on the stock workout app, and that it needs a high heart rate and duration of 20 minutes. My question is, in Health > VO2 max > Data Sources & Access, is your Watch listed?
I’ve just done the same as yourself. 30 mins run, 180 bpm & using the apple outdoor run app. No VO2 max reading. Additionally, the same as yourself, I have no data source & no way to add it.
Done anyone know how to add your watch as the VO2 Max data source ?
I’ve done multiple outdoor runs (and outdoor walks) with an HRM strap. All have usedthe workout app, all have been longer than 20 minutes, and i’ve yet to see a VO2 Max reading. The only readings I’ve seen have been when I’ve gone WITHOUT a HRM strap. Wish there was more official documentation on the algorithm used and how to ensure a proper VO2 MAX reading...
I have the same issue. I had hard workouts (90% max heart rate) and they were logged before iOS 11.0.3. After iOS 11.0.3, the watch stopped recording vo2 max during my hard workouts. I just went for a hard run for 30 min with 179bpm average heart rate with iOS 11.1and watch os 4.1 and no vo2 max. Apple please fix. Using 7+ and series 2 watch.
I think this problem happens when there’s a failure on HRR heart rate recovery data recording. Apple Watch does this HRR reading right after you stop your workout. You have to be sure your watch is well placed on your wrist and there is no chance to fail on reading your heart rate. I’ve said all that because I’ve noticed every time I had a problem on HRR data reading VO2 max was not displayed. And a last comment: I got VO2 max results even with walking workouts of 30 minutes with max heart rates around 140-150 bpm.
I just want to point out, that I get V02Max readings anytime I run over 20 minutes, and I only use the Strava App exclusively, I read some are suggesting that only the workout app will generate this value but for me, the strava app apparently shares enough data for the calculation.
thanks for the reply. Since my post, I have had several workouts of longer than 30 minutes, several running and several biking. Only two runs have returned a VO2 measurement and I cannot tell why, they are not the ones with the longest time or the highest heart rate??
Any responses? I have the same issue. We have several watches in the house adn the others read VO2 and the others users are less active so I don't think it's "Activity" related as others are indicating.
I've had VO2max readings via the NRC app since Oct/Nov last year and still working well. Only works for outdoor run activities and not indoors. So think maybe GPS data is used in the calculation somewhere.
