Notes about this video:

1. My last VO2 Max test was 1.5 years ago, where I got a result of 35.5. Watch that video here: https://youtu.be/n2AfUpYyynE?si=1sqWN-ca-bCBFUY_
I'm surprised I got a higher score compared to 1.5 years ago as I considered myself much 'fitter' then. I did lots more running than I do now.
However, I am  more specific and focused with my training now, and much healthier.

2. None of the devices are sponsored. I bought them all, which cost a few bob 😅
I got so intrigued about each one so just went for it.
It's interesting comparing the data and the advice they give.
Let me know if you'd like to see a video about certain devices.

3. This is how long I've been wearing each device:
- Garmin, almost 10 years.
- Apple Watch, 5 months
- Whoop, 4 months
- Ultrahuman ring, 2 years

4. I’ve been wearing a Garmin for almost 10 years, which is why I think it's over estimating my VO2 Max - I think it’s taking into account all the running I did over the years when I was much faster. But cantle be sure that's the case.

5. I've set myself a target of getting my VO2 Max to 41-42 in the next 6 months with the training programme that was given to me as a result of doing this test. I will go back in November and retest and see what improve I can make.

At last a proper scientific test with actual data. Thank you.

Thank you for doing this test and sharing the result with the community! It's good to know that smartwatches got to the point of providing measurements close to the actual lab results. Gives a peace of mind.

I never regret it when I watch one of your videos.

My VO2 test was in 1988, like you did & got a 69 but now i am interested in the good cardio fitness at 78 old . So i restarted my running 2 years ago with Park Runs , shuffling along . Thanks for all your videos , always informative and honest. Greetings from Sydney.

Great video.  Thanks for producing.  Very helpful as I prepare to have my first VO2 Max test.

I’m a 83 year old male and recently had a treadmill based VO2 max measured of 23.2 - which agreed quite well with my Apple Watch indication of 23. I was surprised because my Apple Watch “workout” recordings are based on daily walks with the dog which are with many stops/starts for her to investigate. The Apple Watch tells me I’m “below average” but the categories don’t represent my age cohort. Any others here 80+ with VO2. Ax measurements?

In my 60's and recently had the V02 max test done and my result was 45. My Garmin device says 43 so pretty close. Nice video thank you for it.

I took a VO2Max test on June 3. Age 57... I run 4,5 years, my PB in marathon is 03:14:15". My Coros Pace 2 watch read 46 and the final test was 50.6. I am super happy with these results!!!🙂

Stumbled across this vid and was hooked. Feeling like I need to book a lab test now lol. Great vid!

Wow, an absolute banger of a video! Thank you so much for documenting your lab test experience. As an Apple Watch owner, I have been wondering about the accuracy of my device.

Good onya Laura, you delve into all things fitness-wise with such enthusissm and the ability to explain stuff even my 80 year old brain can comprehend. Thanks for all your hard work.

Thank you for such an excellent video. It's not just about the devices, but I learnt so much about lab measurements. Your tip on getting accurate VO2 max from the device is useful. Subscribed and liked. Following for more interesting content. 🙏🙏🙏

Good to see you running again, it gives you the best of both worlds/ health. My Garmin tells me that my VO2 max is 45, it’s on the upwards trend with all of the speedwork my Runna program is giving me

I had my VO2 max tested in the lab twice; once on a bike, once on the treadmill. The results were 56.8 and 56.9 so pretty much the same. Garmin gives me 55 so it's pretty close to the actual value. For a 43 yo woman, that's pretty good, Garmin says top 1% for my age group and gender. It does track in local races where I place on the podium on my age group more often than not.
The lactate threshold estimate of Garmin is pretty close to field tests as well, usually within 5-10 seconds per mile and +/- 1 or 2 bpm.

That was a really interesting video with a lot to take in. I’ve just recently got a Garmin and my VO2 is at 42; top end of green zone, with blue & purple still to go. I’m 58 yrs, so fairly happy.
Thanks for posting such a helpful video.

My second Garmin device died around a month ago, never going back, just purchased the Amazfit t rex pro . Absolutely loving the information I'm getting and it seems very accurate when I'm comparing it to other devices

I recently got a Garmin FR165 and based on your video, I'll be quite fine and confident with Garmin's VO2max estimates. Thanks! Cheers from the Philippines! 😇

Great explainer Laura! thank you for telling us complicated stuff in such a simple manner :)

Great video...great effort on the treadmill and the Lab Tech is brilliant...well done, both of you, well done indeed.
