Garmin V02max

[Mauricette Atencio]

I've read that this watch uses local weather data from your phone to get the temperature and then adjusts V02max accordingly during your run any time the temperature is at 72F or above. I also read this is done behind the scenes, meaning we have no data to see exactly how it's doing this. This is fine with me and nice to know if it's compensating for the temperature but I don't run with my phone. When I sync with Garmin connect however at the end of my run, I always see a temperature tagged to the run, which I know is coming from my phone during the synching process. So is this still a valid calculation? I will likely be running above 72F for the next 4 months.

Thanks for the replies, I have seen the Garmin page about the supported watches. I was reading a comprehensive 3rd party review here: www.dcrainmaker.com/.../garmin-forerunner-245-music-gps-watch-in-depth-review.html that states the temperature compensation is supported but I guess it's not so.

HermanB Can you clarify? The support FAQ linked above omits the 245 from the list of compatible devices with heat-adjusted and altitude-adjusted VO2max, while the owner's manual says: "Your device adjusts the VO2 max. values for heat and altitude, such as when you are acclimating to high heat environments or high altitude."

I used to have the same VO2max with last summer with 245 like now with 945, I was also running with them paralel also in hotter conditions without seeing any difference. Therefore thinking it's calculated based on the same manner. But good if somebody confirm this officially. Where is the difference, 945 can measure "heat acclimatization" in addition but this is known.

Hi

With my first training plan I let Garmin recalculate my LTHR and pace settings all the time. Eventually I calibrated myself off the plan.

My suggestion is not to take Garmin suggestions that seriously. If I would listen to Garmin I would sometimes need to rest for 2-3 days after intense run but 80/20 plan says that tomorrow is training day. I do the runs and garmin actually finds me productive although it said I should rest.

Just listen to your body and follow the plan as close as your body lets you. Do some talk tests or 20min tests to reassess LTHR and take care of you muscles and mobility to stay injury free.

The worst drop I ever saw was when I was in New Mexico and decided to track my hike to the top of the mountain. The elevation was much higher than where I live, plus it was a steep incline. I guess Garmin only accounted for pace and heart rate, and consequently must have thought that I was completely out of shape!

No, it is not, but people, especially those who do not run, still want it, although it is practically useless. It is a brutally approximative estimate based on the pace and the extrapolation of the HR. Unless you use to walk in the Z4-Z5 (resp. at +70% of Max HR) during periods exceeding 10 min - then it could have some sense.

Example: You record a Run activity with GPS, which generates a VO2 max estimate. This VO2 max estimate will display in Garmin Connect and will only update over the next 30 days if you record additional Run activities with GPS. Other activity types below in this list will only update the overall VO2 max estimate when the most recent Run activity with GPS is older than 30 days.

Darn it, so if you are doing only 'fitness' in the sense of 'Strength Training' and 'HIIT/Cardio Sessions' .. you basically do not get any VO2Max recordings? They seem to be based on 'All-Day Heart Rate', but I doubt that is any good metric. Not sure how would that work.

I have both cycling v02max and walking v02max entries (separate as you had suggested) but Training Status chooses the walking V02max for some reason. Just an observation. Not sure if this is by design or just another issue that Garmin will hopefully fix eventually.

My apple watch ultra vo2 max reads 29 but my garmin is 45. I'm in good condition and run and exercise daily with intense exercise multiple times a week. i've had my watch for 4 months and have set it up to record vo2. The reading seems pretty useless on apple watch.

I believe that workouts recorded using Garmin do not contribute to Apple Vo2 Max scores which is why my score is dropping even through my fitness has remained stable. This might explain why, if you are using Garmin, Garmin scores your vo 2 max value higher then Apple health because it is using all the data from the Garmin devices.

If I go into the Training Status glance and scroll down to VO2max, I get a graph on which it's possible to visually determine VO2max to about 0.1. However, I can't find anywhere else on the watch or on Garmin Connect that gives this degree of accuracy - everyone else it's just reported to an integer value.

Given that once you hit a certain level of fitness, your VO2max changes become very slight, only reporting them as whole numbers isn't very helpful as that might only change once a year - giving the extra granularity of one decimal place would make it much easier to identify trends and understand the impact of your training regime as well as avoid any nasty surprises when there's an unexpected drop.

My runalyse account v02max does not show the same info as the watch (on training status-v02max). Watch shows 56+ while runalyse show 55.59 Something must have changed on garmin's side. Like calculating values on treadmill.

to the left is data from runalyse from this week. last entry is from a treadmill workout. Previous one track session with GPS. To the right my watch does not show nothing below 56 since 1 week at least..

If only I was a well-trained athlete though. I'm still trying to get my VO2max back to where it was before I had an accident 4 years ago which, adjusted for being 4 years older, should be about 52/53 by my reckoning.

Regarding this question: But that's the issue - how can I tell if it's plateaued if it's only reporting whole numbers?

When you go to Training status > VO2Max you will see graph which is changing from day to day and arrow side to numbe which indicates current VO2Max trend.

Suggestion for the moderators/platform designers, would be great if Strava introduced measurement of VO2 Max. HR is currently measured, this could easily be integrated to work out a user's VO2 Max score, and have this split into 4/5 zones, as they do on Samsung Health. This would help me track my progress a lot more and give me more motivation to improve, especially when it's bloody cold like it was this morning

In the comments below, would you mind giving a brief summary of what VO2 Max is?

In doing so, you could inform those not familiar with the measurement on how this could be beneficial to athlete's if this was added.

VO2 max, or maximal oxygen consumption, refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. This measurement is generally considered the best indicator of cardiovascular fitness and aerobic endurance. The more oxygen a person can use during high level exercise, the more energy a person can produce. This test is the gold standard for determining cardio-respiratory fitness because the muscles need oxygen for prolonged aerobic exercise, and the heart must pump adequate amounts of blood through the circulation to meet the demands of aerobic exercise.

Strave has an option where you can personally adjust your max heart rate. which is nice, but maybe they could allow for more details/data to be inserted onto Strava based on the individual's own score/info after such a test to track more accurate progress.

This is a good idea in general, but most athletes who actually care about VO2 Max are already using a device such as a Garmin with that feature. If Strava adds their own VO2 Max metric then the results for some users will inevitably be different from the Garmin (FirstBeat Analytics) metric, and then they'll complain and argue about the discrepancy.

But would it not be great if you could manually insert your results from your vo2max test into Strava so that their own Vo2max metric is adjusted to your data? i don't have a Garmin or sportwatch, my heart rate monitor chest strap connects directly with Stava. so I have a very accurate heart rate measurement, now I just need to sync my VO2max into Strava and that would be all I need!

This is a nice idea and certainly can be useful as a way to track progress but people should know that the values estimated by other programs (eg Garmin, which I use) are often so inaccurate that they are not representative of VO2 max at all. My experience with the Garmin VO2 max value, derived in my case exclusively from chest strap HRM data, is that it is off by about 50% from the result I get in a lab test. Personally I think the Garmin race time predictors are a much better way to track progress. Though if the implied VO2 max metric could somehow be calibrated by manually inputting lab test VO2 max data as someone suggests above, that would be very interesting.

Some good views on the VO2 Max accuracy from our community. Given that the running watches could really be giving an estimate and not completely accurate. Then syncing your watch to strava could also mean that the results will be inaccurate. For instance, those who have a HR monitor give the same feedback that the results are extremely different. We therefore need to think about this further before any action can be taken.

Letting users add their own lab test VO2max and max heart rate is a good idea, letting Strava guesstimate wildly inaccurate data the way Garmin does is not. That will only push lots of people into running in the wrong training zones just because an app tells 'em to.

@Rogier well said! my thoughts exactly. it's why i don't use a Garmin as a middleman but have a chest strap, which is more accurate, directly linked to Strava. but then Strava still needs to interpret the data correctly. we can already adjust our max heart rate on our Strava account, but if Strava would allow for more relevant data/metrics to be inserted based on our personal Vo2max test results that, would be great.
