I've done VO2 max lab testing a handful of times (a few times each year over the past 3ish years) and each time the results are bang on with my Garmin Fenix watch.
Garmin VO2Max is more accurate for people using cycling power meters rather than from running or any other activity where power metrics/estimates are less precise.
@@indonesiaamerica7050 I've been more of a runner until recently (been doing bike events now) and my last lab test put me at 55 V02 max while my Venu 2 showed 53.. then what'd ya know my next run or two after that my watch updated me to 55, lol.
@@sugonmaballs The reason the updates are delayed is that the algorithms wait for recovery HR data (subsequent workouts and even better if you have 24/7 HR data). Some of the earlier watches updated the estimates with each session and people got tired of it because they expect this value to be relatively stable. A VO2Max test can get an accurate test of your maximum oxygen uptake for that test session. For professional athletes it is relatively stable because their exercise regimes are also relatively stable. The ramps tests are even scheduled at similar phases of their season. Also, the ramp test itself can lead to better fitness once you recover. Ramp tests were originally developed for cardiologists and the first MD to use this on a professional cyclist to plan "training zones" that I have ever heard of was Dr. Francesco Conconi. He modified the ramp test to calculate a narrow HR training zone for Francesco Moser in the early 1980s. When Moser trained for the World Hour Record he was doing Conconi's "sweet spot" intensity for 20 minutes on 3 times and I think they varied the "rest" intervals in between.
@@indonesiaamerica7050i had a spiroergometry a couple weeks ago which tested me at 60ml/kg/min and my garmin says 50🥴
@@sirclemeni1 Check the Max HR recorded on your Garmin and see if it differs from the lab-tested value. If Max HR is underestimated in the Garmin it will effect your score because it assumes that you're working harder as a percentage of your max than you might actually be. Especially if you have a difference like that.
I agree that unless you are a pro athlete, or just very detail orientated in the way you go about your fitness data, then it doesn't really matter too much how accurate the VO2 Max of your wearable is, as long as it is consistent. What I mean is that most of us probably only use VO2 Max as an indicator if our training is fruitful, meaning VO2 Max growing over time, and for that it doesn't really matter how accurate it is calibrated. The problem might of course be that if your watch is not well calibrated then chances are that it isn't very consistent either, but if you can longer and faster over time then you are probably doing something right 😄
Bad calibration does not imply bad consistency. These are entirely different things. Think of a thermometer where you lost the scale. To calibrate it, you'd need at leat two data points (i e. temperatures). But even without any such calibration, your thermometer will be perfectly consistent.
@@MiccaPhone I never implied that bad calibration meant bad consistency. In fact quite the opposite, saying that as long as it is constant it does not matter too much if it is well calibrated or not. What I did imply was that a watch that was not calibrated very well might not be consistent either, or in other words that you very often get what you pay for and the higher accuracy, calibration and consistency usually comes with a higher price tag too. Then add the limitations as to what can be fitted into a watch and of course the fact that serious and pro athletes do not use a watch as their primary data source, but strap into proper scientific lab equipment to get the most accurate data.
@@MiccaPhone unlike the thermometer Garmin and others do not measure VO2 max directly, it is estimated from HR variability and your physiological data, weight age etc. But having said that if it tells you VO2 Max has improved then it probably has so what it tells you is relative. The problem actually is that the reading is not reliable because HR and its variability are affected by other things which are not measured and compensated for. For example your core temperature affects HR so does your metabolism.
Yes, like all relative measurements, precision trumps accuracy
Here is counterpoint: if you collect inaccurate data over time, then an upgrade happens, new watch or new algorithm in the software - boom.. all your collected data going to garbage, or you will need to do retroactive adjustment. It happened to me with my old weight scale, which had ~4 lb inaccuracy, I had to retroactively adjust my thinking about my weight going back for years, lol.
Amazing video showing this! I've always wondered if it was accurate but the results are impressive, looking forward to your follow up video in the future.
Wow, thanks. The algorithms have improved! I'm actively using my Polar now, but I've noticed my Suunto consistently indicates the lowest VO²Max amongst my watches.
Very helpful. Before this video I doubted and did not use the VO2 Max on my Garmin. Now I will certainly use it. Thx
Great job! Thank you. I work as a Health and Wellness coach, and was curious about this exact topic, being a Garmin Instinct 2 owner.
Great video as always! Thanks for your efforts Dave!
My VO2Max was 59 before I contracted Covid. When I picked up running again after 2,5 weeks my VO2Max had dropped to 54. It took quite some months to reach the 59 again. Now, exactly 2 years later I am at 62. I have a Garmin 255.
How do you like the 255? I’m seriously considering it…
I don`t know about before the covid, but after a bicycle accident, then the second lockdown, then catching the covid, which progressed into long covid, mine was 26 in the beginning of January. By end of April I managed to reach 42, so still long way to go
Mine was 51, I got covid in feb 2023 for the first time, and that seem week I crashed my bike seriously, and broke my clavicle and 4 ribs, and messed my hip up. I only took 2 weeks off exercise, I was back on my indoor trainer after two weeks, but now two months later my V02 max has basically flatlined around 42. I feel super strong on the bike, and I'm competitive in C grade races on Zwift, but my VO2 max just won't increase. So idk if it was covid, the crash and subsequent surgery, or a combination of both.
how does telling us about yourself add value or more info to this video
@@AM-bl2csassuming that you tested the vo2max exactly the same way, all you need is more patience because full body recovery after serious accident takes way more than 2 weeks. You should keep testing and exercising for at least 90 days and see the progression back to 51.
Good review, interesting and relevant thanks for the job done 👍
In general even if data from watch is not precise, it's possible to track the trend, which is more important than the value itself
Thanks for this very interesting benchmark !
Interesting video! My vo2max for running was at 62 during college and hovered around 60 afterwards. In 2019, I got bitten by a tick and infected with meningitis. My vo2max fell to 41 over a few months, because I couldn't move a lot and my left leg was paralyzed. Now I'm at 52 again and it's still climbing every few weeks. My values with a Fitbit and Garmin were consistent with the cooper test results, polar resting fitness test tends to give me higher scores
Citrobacter Freundi is the bacteria responsible for meningitis. I have a gut infection from it and I'm Siga Deficient (and I assume you most likely are as well as ppl with a good immune system can fight it off). How did you beat it?
My curent Vo2max is 50. A year ago I reached 53... I use Garmin Fenix 6x and I can say that I am in high shape and I have never been in a lab. I was really glad to see your video, it verified the numbers for me. By the way I am 63 yers old.
Thanks for the video😂
Mine only 35. And I'm25 😭 and my bmi is normal though
Awesome video as always. Was always curious how accurate my Garmin Forerunner 955 score was! Super interesting.
I've seen some similar videos but this one is by far the most informative :) Cheers!
Glad it was helpful!
Amazing video and explanation about VO2. 👏👏👏
Really pleased that a bunch of watches had a very accurate score, especially as they are only estimating based on the metrics they collect!
Answer: Quantified Scientist
Love the video!!! I am also a data guy when it comes to my training and this is really cool to see!
Thanks Dude, appreciate the video and insight on the watches. I personally wear the Garmin 945.
Thanks for the video. At my age, 71, and standard of athleticism, which is at best modest for my age, I have considered it an expensive overindulgence to go to a lab to have my VO2 Max calculated and have relied on my Garmin Forerunner 245. However, I pushed my score up to 46 from 44 late last year and was surprised to see it raise to 47 last month. I suspected my trusty watch might be flattering me: apparently not.
Pheeeew!
Good to know that the watch should be close. The HR zones though seem to be super helpful info, so I might try such a test. Thanks for the cool video!
Very cool. Glad to see the watches are pretty darn accurate
Wow, thank you so much. You describe that very well.
Very interested and helpful. Thank you.
Greetings from the UK! Excellent idea for a video, and the first I've seen like this. Very impressive and useful, and I was very surprised at the agreement between the lab value and Garmin, Apple etc. estimates. Even the ones from the not-so-good camp were closer than I would have expected, so it seems that the VO2 Max is, after all, a useful metric! Even The Quantified Scientist and DCR haven't done a comparison like this, as far as I know. Thanks
Glad you found it useful!
@@ChaseTheSummit The follow-up later in the year will be even more useful!
Look forward to part two! Thank you for testing. Hit those two pump Burpees (100 reps) and let us know the VO2 Max. Thanks.
Interesting! I just did a vo2max lab test with a score of 51 as well. Garmin gives me a 50, so pretty accurate. Been using a Fenix 7 for over a year now.
I'm 34 years old, regularly strength train (I used to run, but had to stop for a long time due to injuries), and my Fenix 7 said I had a vo2 max of 35. Then I started heart rate zone 2 training for a couple weeks now, and it said my vo2 max decreased to 34 lol. I guess I'll keep training though because I can't do a light jog without my heart rate increasing to like 184bpm even though I can sustain it for several minutes without issue. That shouldn't be possible since that's a max effort heart rate zone, but it's like that every single time I try to jog. I've just been doing treadmill incline walking to keep my HR in the correct zone, and hopefully it'll improve things over time. I suspect this is the result of covid because, not that I ever tracked it, but I never had aerobic fitness issues pre-covid, but who knows?
@@someguyusa The short version of the story is that you went through a period of detraining and now you need to follow "base building" doctrines like keeping your HR in the conservatives zones so that you can do the hours at low intensity first and watch your HR data start to improve without stressing yourself too much. It seems like you're doing that anyway but you should follow "coming out of off season" (or illness) style base training. These patterns are totally normal. And viruses do stress athletes in this way especially if you're forced to reduce your activity levels for more than a few days.
Thanks for this great video again. The interesting part of this vo2 max is, my vo2 max is 47, and I used to do sports 3-5 times in a week, but my gfriend`s vo2 max is 50, but she does not used to do sport so often as me. So I don`t really get it. BUT, when we are hiking she is more durable with a higher pulse. Maybe the vo2 max is the main key of her durability. Thanks for all!
Thumbs up. I am in the 40-49 bracket and my vo2 max, according to Garmin, is 56 and my physical age is 20! Never had the curiosity to check that metric until now, thanks for your interesting explanations.
Mine is only 35.. I'm25
Just switched to a Garmin 965 from a Polar Grit and I find the HR readings very similar on both. I’ve been using the Garmin for 16 days and it gives me a VO2 max of 50. Polar gives me only 36 Vo2 max but on Polar running index on my daily running Polar give’s around 60-65. I’m 68 and first used the Polar HRM over 30 years ago and would say HR varies a lot from person to person so Vo2 max is the same. You can’t really judge yourself against other runners using this data. The quicker runners generally have lower HR but it’s not always the case.
Hi, may i know how long to get the vo2max data with garmin?
I think it's great how you pointed out fuel points to zones. I think a few of the next adventures I'll be getting a pro Vo2max
Excellent review. Love it!
I would say what matters more than the vo2max absolute value is the vo2max changes through training. Even if it’s incorrect, it may be useful to see how it changes when training. Last year i was running every day for a month, my vo2max did a +4, which was great 😊
Agreed, even if the value isn't accurate it's nice to see improvements!
I am 57 and started a 6 month intensive cycling training program back in October 2021. At the end of the training program, I reached a TSS of about 980/week. According to Garmin, my VO2Max increased from 48 at the beginning of the training program to 53 at the end. What I also find interesting is that the baseline of 48 was stable for several years when I was typically cycling 3-4 times a week throughout the year. However, this spring it took me about 6 weeks of intense training to get my VO2Max back up from 48 to 52.
Yes. The number just has to be repeatable. Like using a power meter on my bike. I dont care if it is 2% non accurrate. Meaningless. And my scale too. Hopefully it isnt accurate either!
I was waiting for this for so long!! Great vid!!! So curious to know what is happening with this metric… have been stuck to 50 for months at my garmin and my AWU at the same time gives me 43!!! Weird right??😅
This is a very interesting test and thanks for the explanation. I only have a Garmin 55 since almost 3 weeks and it says that my VO2 Max level is "good" (Green 44), I cannot remember if at the beginning of July was worst than this. I use to walk and slow run 3 times per week, almost 10km in total (I'm a beginner). I will keep it in sight
Very nice video, thank you! I only own a Fenix 7 so I can only speak for Garmin, but there are actually two different VO2Max scores, one for running and one for biking. I believe you compared the one for running (since the running icon was shown above) to a biking activity at the test lab. Would be interested if your biking VO2Max is 51 as well on Garmin Connect. Being a runner primarily I know that those values can differ vastly .
Fenix 5s, yes 2 scores at least. my cycling vo2 max is 5 higher than running. Big difference especially cause I'm old.
My Garmin running and cycling VO2max are consistently within 2 counts. I do both regularly.
Thanks for the videos. Always useful. I need to maintain a certain VO2MAX level for my job, so always interested in ways to measure it.
I've had a lab test and I've used the 'resting fitness test' with a Polar watch, which was slightly lower than the lab test but consistent. The best, free 'non-lab test' I've used is to do a 20m bleep test with an app that calculates a VO2MAX level. The reason I like this is that a bleep test is the same every time on level ground. Same distance, and same time increments, and you have to work to exhaustion on the test.
Obtaining a max heart rate gives a more accurate reference point when setting heart rate training zones too, which you talked about in the video.
Thanks again.
Thanks for doing this.
Great video. A few comments/observations based on where I am at personally. First, wish I knew more on where Fitbit fell into all of this. I also I have recently gone onto a beta blocker and am trying to figure out my new HR targets. From what I have learned here, I suspect that any smart watch will not help me it getting a reasonable number for my VO2 Max. I am more sure I would want t to do this actual test (I am in the Boston area) out of concerns that it I would push myself too much. I am still trying to figure this out as I am still early into being on the beta blocker. Zone 2 training interests my the most, primarily because of what I have been watching on online content of Peter Attia.
Excellent review!
Great video. I'm surprised at how well the watches estimated the number. I run with a Garmin Forerunner 245 and have identified some weaknesses it its algorithm. The effects of altitude and steepness of terrain cause a variance in its estimation. I do most of my running on steep hills at an altitude of 1500 meters and the V02 max is usually 45. If I go up into the higher mountains and do similar run at 3000 meters elevation, the next day my watch will say the V02 max is 43. Or, if stay at 1500 meters and run faster on a smooth, flat trail, the V02 max will go up to 47 or 48
Good point, I estimate people can find between 10 to 15 variables that can affect accuracy. Next question is: does lab test have similar weaknesses?
great vid, but for the rest of us, the important thing to understand is whatever your score, and whatever it's consistency with lab testing might be, all you have to do is ensure it's maintained/improved over fairly long time scales
My Garmin Fenix number also matches the real VO2 max test I had. The real interesting detail however is the fat burning percentage that came from the real test. In my youth I ran 5 marathons within 5 years the same way. I had no clou on fat burning versus carb burning. So I ran straight all out for 2 hours and something, and ran straight into "the wall". From there the last 17-20 km of the marathon were 100 meters of walking followed by 500 meters of slow jogging and then down to walking again.
Now 26 years later I'll be running a marathon again next sunday planning/hoping/praying to beat my old personal record because of the knowledge of 1) my fat burning at lowever intensities, 2) my inability of taking in carbs whilst running. I have to stretch my blood sugar reserves to last for the whole marathon. Wish me luck :-)
Good luck! If you are in ketosis you don't need glucose in the blood stream. So perhaps go for that?
I use a Polar rest test, Garmin 530 computer bike ride results, Strava and Zwift ride results. They are all within 3.5 points on their estimated VO2 for me.
Very good presentation. Also I am biased and use a Garmin watch. I had a lab test, but I confess, being claustrophobic, I had a very difficult time completing it and my results were not conclusive. (A pity, because yes, one does suffer with this horribly strangulating mask on one's face and my suffering was not rewarded). Garmin results did seem to be accurate given my age and training regimen. VO2 max remains static, so I imagine I must have to crank up my effort to raise it a point or two.
Good video. Thank you.
Cool to see that some of these different watch brands are consistent with that of an actual VO2max test
Not really. Some individuals will get an accurate number, some not. Max heart rate will differ +-20 beats in a age group. That and what data you put in will affect the result.
I use my coros metrics in combination with runalyze and they are pretty similar (52 for coros, 53 for runalyze). I use them for race prediction times and more or less they are right. I also have the huawei gt runner and its vo2max estimation is way off (62)
This video helped a lot with knowing how accurate my Garmin was. It says I get 59 which is great to know!
What I suspect is even if the SmartWatch is off a little in absolute value, I bet relative changes are tracked pretty well. If the watch says you’re getting better (or worse) I bet that is probably pretty true. Will be interesting to see your follow up.
For sure, I think that’s more valuable than absolute accuracy. It’s nice to see things trending up when you’re working hard!
Thanks for the informative video. My Polar fitness result comes in consistently at 5 points over my Apple Watch VO2Max. Looks like based on your findings, I stick with the Apple numbers. Another way, according to some top level coaches, is to use RPE which might be a more accurate way to estimate your training zone as it takes into account all the daily variables and influences.
Whats RPE?
@@seekdiscomfort4746 Rate of Perceived Exertion
@w ss oh yes, then I applaud you, you're spot on! My old running coach would call using RPE, common sense training amd it is actually logical and makes complete sense. It's kind of like why at the beginning of hitting your heart rate sone that you're training, in you're RPE is naturally not going to be as high as compared towards the end where your RPE will be extremely high, yet in the same heart rate zone. And of course like you said also includes other factors of the day affecting you're perceived excertion, i.e heat, humidity, elevation, even nutrition, hydration and state of muscle soreness!👍 👍
I only done VO2 on my Garmin and it’s a 68 as a upcoming college runner for a njcaa D1 school.
Just a thought. With the Polar the important thing is the average value it keeps, not that for a specific activity, or even a day's activity. I think its a rolloing average of some sort using the last months data. So if you've been using a polar devices regularly you'd expect a good VO2 max value, if you haven't you shouldn't so much. If you have used any Garmin, Coros, Suunto devices regurlarly recently you could probably expect more accurate results. And that's not the specific devices, any device from the manufacturer as the data is held centrally. As I remember using garmin & Coros what you saw was effectively a rolling result? Though maybe that's changed. Having said all that, Suunto & garmin are also using the same FirstBeat algorithms? I'm not sure what the other manufacturers use (obviously Polar have their own).
hi Dave, my Garmin 6 pro gives me VO2 max 51 same as yours , i also got ' old watch"' polar grit x Vo2 estimate 63 polar is way off. great review by the way.
My Garmin has me at Excellent and my apple watch Series 6 had me only at "Above Average"! I have been using a Polar HR strap consistently for my runs/trail runs. I'm curious enough to consider getting a lab test to nail down those heart rate zones (might be humbling.) I suspect the Apple watch is more accurate, but who knows! It's all for fun.
Very interesting video. I made same test 5 y ago. I got on my Garmin F5 same Vo2Max value as measured in lab (55 vs 55.4). HR zones +-3 bpm calculated in lab vs Garmin auto detected. I always use HR belt. With optical sensor i got really higher HR values, mby becouse my hand is too hairi :D
The HR Band is the key for a more accurate VO2max. It changes all the metrics!
Really interesting 6 I've always wondered re my Vo2max using my Garmin Fenix 7, which is currently sitting at 65 - for context I'm 40 and run.
Dave, for Polar you should have looked at its moving average in Polar Flow, not only a VO2max from a single run.
VO2max estimates can substantially deviate between runs.
I see that in Runalzye, where my VO2max estimates range between 49 and 53 betwen runs, depending if I have a good day, I do tempo runs or if it is too warm
For sure, the point I was trying to make is that most of the values I have in Polar Flow are wildly different and none of them are close to the lab test. VO2 Max is an absolute number so I’m not sure why Polar has like 5 different numbers and tests. Thanks for watching.
@@ChaseTheSummit it mght be worth trying the running test, if it's available on the Polar watch you have.
Always been keen to get a proper test, im currently floating around 64 and wonder how accurate it is
I'd be curious to see what the HRV4 Training app showed. I use that and COROS and they are quite different, even tho HRV gets the data from Strava and therefore the COROS watch.
Thanks buddy!
Great info!
Hi, great review & comparison. But here I would recommend to try also one interesting tool - runalyze. There present algorithms to estimate VO2max even for each run. Also nice graphs to see how it changed with time.
I read that to have accurate vo2max estimations you need to input an accurate max heart rate - which you can find doing field tests. And also measure your resting heart rate in the mornings once in a while.
I remember when the Microsoft fitness tracker came out with the Vo2 max estimate and it was a big deal
Interesting vid as I have been wondering about this. My fénix 6 has been showing I have a declining VO2 max which doesn’t make sense as I am getting more fit. Wondering if they had changed the algorithm recently.
My friend did a study for his masters, for exactly this question. He had 8 guys that run with Garmins, had them lab tested and the results were pretty much the same. I think the more popular companies (garmin, chronos, apple) are more acurrate, because they have bigger datasets from their users. But as it was already said, VO2Max is just a number, it depends how well can you put your fitness in use.
Turns out, to estimate your VO2 Max you really don't need a smartwatch. You'd do just as well with VO2 max formulas those watching are using and without the expense to acquire those gadgets. Now, my point is not to dismiss them, as they're quite useful to measure something they actually have built-in sensors for.
Main thing is.....keep running. Don't ever stop.
@@MrAstygmatyk I stopped 35 years ago :(
Thank you!
Thank you dude
Which Garmin do you have and can you please recommend a good fitness watch that won’t break the bank? I currently have a Apple Watch 7 and I’m looking for something different. By the way, awesome video! I’ve been trying to find out what v02max is.
When I switched from a fitbit to a garmen Venu 2 I became extremely interested in Vo2 max. I still want to go get it measured professionally. I'm a male at 29 years old and started with an awful 32 if memory serves. It has been a year and I've been able to raise it all the way to 59! Your video is among the most clear explanations I've seen and I love the test data you showed. Thanks a bunch! (Edit: typo)
I have done VO2 max lab test with score of 49, but my Garmin woefully overestimated it at 57! Stick to a lab for accuracy.
Good to know how close our watches can be
I made a VO2max test. Result 57.6, Garmin said 52.4.
I think Garmin might struggle with trail runners. Either that or it is due to me improving quickly in recent month and Garmin being only able to track slower changes.
Epix 2 Titan Sapph is a - must watch!
I had Amazfit in the past, right now i have Garmin, both were almost at the same level of 51-52. I didn't test myself in the lab.
Thank you,thank Garmin👍
My Garmin Forerunner 935 says my VO2 max is 45 to 48. I was just tested at a lab at a 53.7 VO2 max. I ignore alot of what my watch tells me. It often says I'm unproductive because of VO2 max drops. I run ultras, so I run zone 2 most of the time. My VO2 max goes up after my hill/speed workout day and drops after several easy runs. I work a crazy schedule, so I often have to move workouts forward or back a day or two and swap runs. I still get my miles, but Garmin is guessing metrics based off a 70 mile week and a 30 mile week.
good channel, man
Good to see you testing this! I had my VO2 Max tested back in Februari (it was part of a complete sport medical test, done because I'm training for a full distance triathlon and wanted to know where I stand in terms of fitness/heart rate zones/etc). My Garmin Fenix 6 was at 53, but the test results returned 59 (42 year old male). Quite a gap between these two numbers. I have often heard that the results are sometimes further apart. Also interesting to see the table with what kind of fuel your body needs in different zones. This wasn't part of the tests I did, but really want to know now :D
Tested often myself with Suunto Sports software, and the fat expenditure rises with sets when HR stays on the level possible to continue the activity, from 20% fat in the beginning to 80% after 1.5 -2 hours of outdoor hockey games with many (20) sets. The body burns all the carbs and then recovers and uses mostly fat. That's why low HR is preferable for long-range runners, the body burns fat with low HR./ 65% of MAX HR in my case.
Your V02 max is exercise specific as the type/amount of muscle mass utilisation differs. Something to keep in mind when trying to validate your v02 max measurements
This...
VO2 (Max) is a way to estimate the efficiency of the Oxygen delivery chain in the body, from Gas inhaled to oxygen delivered at the muscles for exertion. Ofc it will vary depending on which muscle groups are being involved.
I did ask about this at the lab and was told they use the Assault Bike as a way to mitigate the differences between Running and Cycling VO2 Max since both hands and arm muscles are used for the exercise. But yeah, I agree there's probably a difference and I would certainly be more comfortable on a treadmill... Next time!
The watches are pretty close if you have a normal size and leaner build and run/bike a variety of paces/zones.
Hi 👋🏻 Great video. Love the channel. Can you run the Cooper Test as well for a future blog? It’s the oldest of old school, but it would be interesting to compare all three results together.
Stay tuned, That's coming in a future video!
@@ChaseTheSummit Awesome. Can’t wait 💪🏼👍🏻
Hi Dave, Neat job! I wish you had included the difference in VO2 measured by the device itself and the addition of heart rate straps or any other optical sensors. Also, I want to know how devices like Amazfit Falcon, and T Rex Pro are accurate with or without external sensors. Thank you very much for all your efforts!
In this video almost all the measurements were done with the on-board optical sensors. However, I do run with chest sensors from time to time so that will be a factor in the Garmin/COROS numbers. In my testing so far I haven't had great luck with the heart rate sensors on the Amazfit devices including T-Rex and Falcon.
Great video man, VERY interesting and useful.
I'm in great shape but my Apple Watch gives me a pretty below average VO2max level for some reason. I train almost every day and I go at it pretty intensely, both in cardio and in strength training. I was starting to doubt the accuracy of the Apple Watch in the VO2max estimation but this video points towards the direction that maybe my knee injury or something else is the actual culprit of my low VO2max estimation.
I will keep on searching for the cause and for ways to improve this number, including specific training. Thank you for this information and, if you have any tips or pointers for me in my VO2max journey they would be VERY welcome.
My Apple Watch does the same and it says I have a below average vo2 max. I’ve now also got a garmin and that says I’m very fit and in the top 20% for people in my age group
Maybe the new apple ultra watch is better
I have the normal iwatch model that came before it
@@steveh8758which one do you have? I have a series 6 and it’s way off
Interesting topic.
Great video! Did the training zones from the lab and the ones from Garmin also match?
Greetings from Germany, struggeling to improve my 43 😀
They were close but a little off
I got the same results when I was tested, very close to what my Garmin showed. There's a company in San Diego called Body Comp, they do V02max testing and also DEXA scans, and not too expensive. And while the V02max was pretty accurate, the Garmin Index S2 smart scale is nowhere near accurate, in fact every bio impedance scale is going to be off by a mile, but they're useful directionally relative to you.
I have noticed one flaw in the software algorithm type V02 estimates. In the "off season" when I'm training in Zone 2 and focusing more on building a base, my V02 score will plummet because pace is an important metric in the calculation. I think Garmin and others could easily fix this by creating a V02 workout widget that takes us through a V02 test and overrides the current setting.
Another thing I wish Garmin would do is to allow us to save/record recovery after a hard training session. Why give us this option post workout but not save it to the workout as a measurement, or perhaps even factor it into the V02max formula. For example, I might do an interval workout where I'm doing 1000 meter max efforts with 90 seconds of burpees x 8, this will max out my HR for almost an hour, I always hit the recovery afterwards, before saving, but the recovery score doesn't get recorded....why?
It annoys me that Garmin doesn’t utilize the recovery time, considering all the metrics they throw at the wall to sell as “useful” and yet…no saved recovery time. It is actually saved in the data file (for example I can see it in my linked Apple Health). But really, I’d rather have that 2min recovery HR in Connect, and on a graph over time, etc. In garmin forums people have asked for it going back 7+ years, but garmin is crickets for what ever reason.
@@staticpurge Just create a "recovery lap" at the end of your recorded activity session and that is available to you and the algorithms. Once the "activity" session ends there is less data to record and it becomes less reliable. The algorithms factor in all fluctuations. The part that is weighted the least is warm up phase and you know how it tracks that by tracking the "performance condition" rating.
I got a VO2Max test last year and scored 69 - I was chuffed to say the least, especially since my Garmin had me at 56-58! I've never been into sport, and only started training more seriously in my early 30s, about 8 years ago. I guess was what is called a slow guy with a high vo2max, but after learning this I've made an effort to train to better utilise this and the gains are coming in thick and fast :D
Holy crap, 69 is really good
maybe you are skinny. The real VO2max is in liter by minutes, that is your real cardiovascular ability, but the number people focus on is the liter by minutes by kilogram, as it is not your cardiovacular ability but a predicator of your performance. If you lose weight the first does not move a lot, whereas the second one does.
@jean martin you nailed it it, spot on! I wish more people understood exactly this! Kuddos 😉
@@jeanmartin963 I'm 5'11 and was 161lbs when tested so pretty average, and measured 5.0 l/min
@@aeriegrove Hi, it depends where you live, with a BMI of 22 in most of the countries in the world you are not average. en.wikipedia.org/wiki/List_of_sovereign_states_by_body_mass_index
And this is the data of 2015, 8 years ago.
excellent video
The VO2 max calculations seem to have issues if you're riding in Stop/Go traffic though. It puts things like commutes and grocery runs into the same bucket.
Just to add that for endurance sports (more than 5k) lactate threshold can be a better performance predictor than vo2 max ;)
VO2 of Kilian Jornet? 🚀🚀🚀🛸🛸excellent video. Very educational, thank you, David
He’s certainly up there last report I’ve seen was between 85 and 92ml/kg/min!
@@ChaseTheSummit 😮😳 OMG!!! This is a very high value!
Good hands on video ! You might want to clarify that the KEY value for watches to offer a good estimate is setting the MaxHR. Set it too high and your VO2Max estimate will be too high and if it's too low well...
It would be interesting if you could also compare the results of Samsung's Galaxy Watch since it is one of the best sellers on the android platform. It would be very nice if you have this possibility to perform this test with this device.
Great video, nice channel. A few additional remarks on VO2max: 1. Body weight is a parameter that influences VO2max (mL / kg / min). 2. The way VO2max is measured (e.g. running cycling) may also have a (significant) effect on the result depending on which of these sports you exercise more. 3. As you get older it will slowly get worse... so just enjoy the ride/run, and forget about performance!
Thanks! I do mention body weight in this video being a factor.
@@ChaseTheSummit Yes you did, but it might be good to emphasize this as you have to enter your correct weight in the watch (manually or with a linked weighing scale). People like me forget to keep it updated regularly (my weight has varied 20 kg over the last 15 years...) , thus getting an incorrect VO2max measurement from the watch, which is not related to the algorithm of the watch, but due to erroneous weight input. I don't know the exact mathematics on VO2max, but a deviation of one or 2 kg in weight might actually cause a deviation in VO2max of several points. Or like in my case I went from a VO2max of 67 (lab measurement, weight 75kg) to 47 (garmin watch, weight 95kg). I would say that for any watch, given the variance in the input, deviation of plus or minus 3 points is very acceptable.
Had a few lab tests over last few years . Vo2 from lab test about 3 points lower each time than Garmin on both bike and run but that’s ok .
I don't have the money for a lab test but yesterday did Cooper test (run as far as you can for 12 minutes then get a v02max estimate based off that)
Got 48.08 which is basically dead on what my Garmin says. I do think I could have done better in the Cooper test but went off way too fast. Very interesting though
Greetings from Greece! My Garmin Fenix 6 rates my VO2max at 62 while my Ergometrics showed 69. I think a chest strap would make it more accurate
My Apple Watch consistently has me high 50s. Did a lab test last year and it was 45 🙃
