How accurate are smart watch VO2 max metrics? Today we find out!
I have a COROS Apex 2 Pro and it currently says my VO2 Max is 57.

This video should have so many more views! Two professionals discussing exercise science in such detail is so incredibly valuable. I have been strength training on/off for years now and I am trying to finally dial in my cardio and improve my running fitness and V02 max always seemed to be on of the those "hocus pocus" metrics that didn't have real meaning to me. Great stuff!

@user-kl3lg7tf3n-anx1ous 7 месяцев назад

Excellent result! Curious if your Coros watch re-adjust your VO2max estimate higher after the lab test (being a max effort and all-so more accurate data for the algorithm near "redline").

@joeyr4869 6 месяцев назад

I would have needed to be on an outside run as the watch uses velocity in its equation

Similiar result for me. COROS says 50 and I tested in the lab at 58. I will give COROS credit for the threshold hr being perfect for me! Right at LT2 at 173 bpm.

@user-do7cn8cq7t Месяц назад

incredibly helpful im a xc and track athlete and was really interested on how accurate my VO2max was on my garmin watch it being 63, thanks so much!

@Irishirich 7 месяцев назад

In all the other videos I've seen by creators who compare their watch calculated V0² max score against their lab test, this is by far the biggest variance I've seen. Most of the other videos usually have the scores within 1 or 2 and the predicted watch is very close to the actual lab number. That leads me to think that the watch might not be getting accurate HR data or it's not taking into account heat, elevation factors which could impact HR on runs. That, or Coros' algorithm is just plain terrible and much worse than Garmin's.

@kylemiller5671 6 месяцев назад

Personally, he looks like a larger than average runner, and the guy was explaining that the muscle he had was the reason the score was so high. Most Olympic marathoners hover around the high 50s low 60s because it's more important to be light and efficient over distance than to be able to uptake more oxygen, once your body is fatigued it won't deliver oxygen well and you'll be carrying the additional load of muscle weight.

@TolunayOrkun 6 месяцев назад

@@kylemiller5671 VO2Max is more relevant for short and middle-distance racing. For endurance races like HM and Marathon it gets increasingly less relevant. LTHR is a more important parameter for endurance racing and for Ultra distances aerobic threshold (the boundary between zone 2 and zone 3) becomes more important.

@Magnulus76 5 месяцев назад

I did a cycle ergometer submaximal VO2Max test, and the results were nearly identical to my Garmin. But there's a big difference between a submaximal VO2 test, which is just an estimate, and actually measuring the volume of oxygen you are breathing in and out.

@Ozzy1984_ 7 месяцев назад

69 is insane. My VO2 max, also on a coros pace 2 watch, is also 57. I wonder what mine would be in the lab. I'll never know, but your half marathon time is quicker than mine, so my VO2 max might be quite accurate.

@AdhesionExotics 7 месяцев назад

Thanks for the video! I was wondering how different your zone 2 range is between your coros and your vo2 max test? Are they both similar (135 ‐153 bpm)? Thanks again, and Happy New Year!

@jeremy.miller 7 месяцев назад

My COROS says my zone 2 is 142-159. As opposed to the lab test that says 135-153

@orbifold4387 7 месяцев назад

69 is great. Based on your 5k PR, and some of the tables/apps found online, your VO2max should be around 66. The Cooper test (12 min run test) should be a good approximation to VO2max.

@nobodydobon 7 месяцев назад

I would love to know my actual vo2max! But I dont wanna turture myself, so I guess I‘ll just stick with the number of my watch😆

@Demiduivenvoorden 7 месяцев назад

damn that incline looked challenging !!!

@arnovereecken2261 7 месяцев назад

Vo2 max is also calculated by weight, and i feel like a lot of people that have a wrong estimate forget to update their weight after they first set up the watch

@francesc5313 6 месяцев назад

Watches use mainly pace and heart rate. Cooper test is good Vo2max predictor and only factor is how fast you can run for 12 minutes. Lab machines like this one measure used oxygen and for Vo2max calculation it need weight.

@thedavidgzz 7 месяцев назад

you should do the fitness test from coros, to see if it adjusts

@drewbdarby 7 месяцев назад

@DailyInspire112 7 месяцев назад

@CiaoMykola 7 месяцев назад

69 is pretty decent. Why don't you try a few different sport watches next time? Would be interesting to see COROS VS GARMIN

@andrewthompson9206 6 месяцев назад

Nice work! I was the opposite unfortunately, lol. My garmin says 57 and I came out at 41.3 on my test about a month ago. It felt extremely hard to breathe with the face mask but maybe I'm just a little B 😂

@rohinkanwal2355 6 месяцев назад

My Apple Watch says I’m at 52 but i tested in lab 68.7 ml/kg/min so there’s a big discrepancy

@xyzct 7 месяцев назад

May I suggest doing a very short follow-up after you've checked your VO2max with the Coros a number of times, and then take the average (and to be be sure you check right when you wake up before even getting out of bed, and after 1 and preferably 2 rest days). My Polar H10 has about a 10 point swing that is highly influenced by how hard I worked out the day before, being _lower_ the morning after hard workouts!

@jeremy.miller 7 месяцев назад

My COROS has been between 57-60 for a while, regardless of the workouts I do. It hit a peak of 60 earlier this year, despite me being more fit more recently.

@xyzct 7 месяцев назад

@jamesmungall6669 6 месяцев назад

I wouldn’t expect the coros to be much good with anything to do with heart rate. You might do better with garmin but I find it hard to trust anything based on optical measurements of heart rate

@peterubishfitness 7 месяцев назад

Holy smokes, that was a much bigger difference than I would have thought! This definitely makes me want to go give this a shot at some point coming up here. I think 69 makes a lot more sense for you though given your marathon time!

@jeremy.miller 7 месяцев назад

Highly recommend it for anyone trying to hone in on race paces and training zones! Lots of useful data from this test

@joe1071 7 месяцев назад

Yeah, wish he did multiple watches. Apple, Garmin, Coros. I’ve seen other tests like this where the Garmin seems to come within a couple points of actual VO2 max. Not sure about Apple accuracy

I want to know how your BMR compares to the estimate on your Coros.

@georgistefanov8919 6 месяцев назад

@jeffcarrol4263 7 месяцев назад

Can you manually update your VO2 data in your watch to match the real metrics?

@mikekirby8196 6 месяцев назад

The confusing thing to me is that all the charts say that >50 at any age is considered “superior” and in the top percentile, yet most comments here where ppl posted their number are in the 50’s and 60’s. I guess it could make sense that many superior athletes watch your channel.
