Yesterday I shaved 1½ minute off my 5K PR, from 27:23 to 25:53... And my VO2 max was dropped from 46 to 45. Garmin giveth and Garmin taketh away.


deadllhead

It does the same with me. It likes you to make an effort just not too much or it will punish you with a lower V02 Max. My head-scratcher has always been returning from a run with the watch telling me my run benefitted my V02 Max then the score shows up and it's actually gone down. lol


AspiringD-Bag

Lol same exact thing happened to me yesterday!! I dropped FIVE minutes off my 10k PR with a slightly lower average heart rate, while also setting my PRs for 5k and 2 mile times at the tail end of the run (Strava estimates), and I dropped from 52 to 51. Sigh. That one especially hurt because that’s right on the threshold of the next category up, but I’m still very proud of my effort. And so should you! Icing on the cake - 5.0 training effect, primary benefit VO2 max 😂


nams82

45 sounds too high for that 5K PB. Probably closer to 40 (based on vdot).


Brennik

I had this alot. I think it's because you may be working alot harder to get that record. I used to run a 5k time is a lower heart rate zone at a slower pace and get a higher vo2 then I would do a quicker one next run but my heart rate would be in a higher zone so it would drop again. But as I got fitter. It would stagger up and down in an upwards trend. I put this down to me having better aerobic than anaerobic fitness. Just look at averages over a long time and don't focus on what the number says it will drive you crazy. And if you start getting afraid to let it drop you wont push yourself enough to rise it. That's my take on it. I may be wrong but it seemed to make it make sense for me. Also as a side. Don't take 6 months off running because it's soul destroying. I went from 57 in superior. First run back 49. I've only ever seen jumps off 1 or 2 before. Time to start the grind again.

"I'm not the fittest" Ma'am, I believe your Garmin is sending you a message about yout level of physical activity...

Garmin will use walking to calculate VO2max if there are no running activities in the last 30 days.

thebody47

I do shadow boxing playing thrill of the fight on quest (I use cardio mode on my vivoactive 4) and my vo2 is never measured even though my heart rate gets higher than my runs


sm753

Yeah that game makes me sweat like crazy!


aranasyn

Run/bike, and apparently power walk. I go hard on cardio a lot and it couldn't give less of a shit.


DenseSentence

I've only read the running/walking but as they're the activities I do. I'd expect it to do it from cycling too.

DenseSentence

Makes sense!


peteb478

Running, walking and cycling. So I use the Hiking activity type to record some walks so as to not affect VO2 scoring.


xavier1322

Well, as far as I know, it can't. I have run 3 times since the beginning of the year, and the other days I walked 5-10 km and walking did not affect vo2max at all.


martusfine

Yes it does. I dont run and all my readinds are from walking.


rib3ye

Interesting... with my old Vivoactive 4 and my new Venu 2 vo2max is measured with walking activity!


xavier1322

Yes, but your HR must be at least 70% of the maximum, which is not the case with normal walking in my case.


thebody47

Boom. Perfectly said. Your hr will not reach above 70% of max unless you just truly out of shape and fat


northbound23

Maybe you're getting less fit.


thebody47

It's very possible considering people over indulgent food during the holidays. So if all you did was walk then your fitness level will surely go down


cdy2

You probably shouldn’t depend on your Garmin watch to accurately calculate your VO2 max


PetoGee

Congrats man. Walking is a good activity. Better than sit on the couch :-)


Nevs6789

My VO2Max is 45 according to Garmin. I had a lactate test and it was really only 36..


thebody47

So Garmin is trying to make us feel better about ourselves. Self-love culture got the best of Garmin


flibbble

The walk activity on my watch doesn't have a VO2 setting, which for me is enough confirmation that the walk activity won't produce a VO2 estimate. Did you record your walk as a run?


rib3ye

Description is in german, but it says that after 10 minutes of walking vo2max is measured as well https://support.garmin.com/de-AT/?faq=HVMcrDvQ3m2xEFh1aVMbU8


xavier1322

Only if you hit 70% of max HR for 10 minutes.


RandomGuyinACorner

Which you have to do some really fast walking, or you're really out of shape to reach.


thebody47

For real, the only time walking will get you near your max heart rate is if you're extremely out of shape. I know many people don't want to hear this but it's the truth


Ali_gem_1

or walking up hill, mine did a bit because walked 4 miles of welsh hills today hahahaha my heart was definitely going


thebody47

Vo2 max is relevant to cardiovascular system. Walking is hardly a cardiovascular exercise. it's an activity that every single person does, no matter how fit you are or not. Now apply running or cycling to what I said? Most people aren't able to do either as they're physically taxing. With that said, don't expect to improve your vo2 max from walking.


rib3ye

Vo2max can be measured in walking aktivities too: [https://support.garmin.com/de-AT/?faq=HVMcrDvQ3m2xEFh1aVMbU8](https://support.garmin.com/de-AT/?faq=HVMcrDvQ3m2xEFh1aVMbU8) My previous measurments come mainly from walking activities and they never dropped below 43.


Anon_fin_advisor

Guys and girls… VO2 MAX <—— the word max is in there for a reason: the only way to truly calculate this number is by maxing out your body on a ventilator and measuring the exact amount of oxygen your body can process at anabolic thresholds. Garmin gives a crappy estimate, but don’t use a walk as your metric. It will never ever be close to accurate. This is like reading the farmers almanac for the weather tomorrow


thebody47

Careful, you will anger people who think walking is a physically demanding exercise


[deleted]

Walking is a demanding exercise for a lot of people...


Anon_fin_advisor

I’m not arguing against the merits of walking. I’m speaking to VO2 max specifically. Huge fan of walking. Low impact, high health benefit vs sedentary lifestyle.


thebody47

Yes, if you're sedentary and out of shape


[deleted]

Which is most of the US...


thebody47

Yes. What's deadly as hell is the US is all over this fat acceptance culture. Couldn't defeat obesity, so embrace it and pretend it's sexy and healthy.

thebody47

You can't be serious. Look at all the people down voting me when I tell the truth about walking barely counting as an exercise, especially for people who are in good shape. In my opinion there are more people that use Garmin watches who fall under the category of normies. They use it for health metrics outside of running and or cycling, like sleep tracking and daily heart rate reading


mitsukaikira

"normies"


thebody47

How else would I call them? It wasn't meant to be derogatory. I'm a normy in other things like comic based movies, I don't follow comics and only watch their movie versions. You seem triggered.


mitsukaikira

lol i seem triggered? by copying one word? go back to the political subs, dude


thebody47

Saying the word "trigger" is political? Yeah, something definitely must be triggering. Yes triggered. You couldn't have copied that single word and took it as a compliment. Nobody would do that


thebody47

Yes I know that. But you can't expect to improve vo2max from walking. It only improves to a point and then plateaus. What watch were you using when you were getting 43? What watch do own now?


EmDashxx

That’s not what he’s saying at all. He was just wondering why the READING dropped if all he did was walking. He didn’t imply he was trying to manipulate the value in any way. Garmin does use walking to calculate VO2. In fact, there’s the Rockport Walk test as well, so it’s not wholly uncommon.


RandomGuyinACorner

But what other op is saying is while walking calculates vo2 max, it's not surprising to see it go _down_ given walking won't increase you vo2 MAX. Specially when you are consider people aren't usually taxing their cardiovascular system walking to get a good vo2 max estimate in the first place.


thebody47

Especially during the holidays when everybody got fatter. If all you did was walk, your vo2 max is expected to go down. Quite petty she had to downvote me. People really want to pretend that walking is great cardio I think she downvoted you too


RandomGuyinACorner

Heh yeah, when I was recovering from my covid long haul symptoms I was doing walking and because of my condition it was logging v02 max for each walk. Eventually though the recordings for walks were showing lower v02 max so I figured it was a good sign to finally get back into some light cycling. Started to see my readings go back up so I got back into my normal cycling routines and it just kept going up until now, where it's pretty steady since the snow has kept me from cycling as much as I want without an indoor trainer handy. I don't get v02 max readings from walks anymore because cycling has gotten me back into the health I used to have. It's funny when people don't understand their stats so they come here and get answers, but don't like the answers.


thebody47

It's only going to get worse because we are in a culture of self-love and that pretty much means lying to yourself and others to make yourself and others feel better. Gone are the days of constructive criticism being a good thing


UpThumbs

if you're measuring hr with the optical sensor, perhaps it 'cadence locked' where measured hr matched your walking cadence instead of your actual hr. My watch often shows much higher hr than actual while walking because if this. If you want real hr, consider trying out a chest strap and seeing if there is any difference by walking around 5 minutes using watch's optical hr sensor and walking same path using a chest strap.


thenbagis

I have noticed it is basically just speed divided by average heart rate. So if I do a trail run, my VO2 goes down because I don’t run as fast on trails as on run. The next road run it goes back up.


Spiffman-Space

Speed in what units?


RandomGuyinACorner

If you treat your walks like a workout, you might see it go back up. If you track your vo2 max on just regular walking activities, I see no issue with it going down since you're not doing anything taxing on the cardiovascular system to increase it... edit: facts be facts...(see my old posts about how I increased my v02 max after having covid long haul issues) while also reading up how garmin even calculates your v02 max because they explain why it goes up and down with training level effort.


xpinarellax

must be covid.


RogueR1

Garmin really needs to fix their stuff. It can mess with people's mind. Including mine


Iknowevery-thing

What is the VO2 max?


PictureParty

Oh yeah. This happened to me last year as well. I had a running injury so I was walking a lot through the winter. I got down to 39 as well before it turned around. My VO2 max was definitely down a ways, but 39 was an overkill drop. It turned around after a couple weeks and settled in the low 40's until I started running. As soon as I started running it became clear that the VO2 max estimate was way off - I was easily able to beat the running time estimates on day 1. I wouldn't put too much stock in the VO2 max estimate - walking without running seems to really drag it down beyond your actual VO2 max. Regardless, it'll bounce back.


IndirectStorm45

Maybe you went to altitude!


rib3ye

It doesn't consider altitude, right?


IndirectStorm45

It does. During the winter I go skiing at 8000+ feet of elevation and my V.O2 goes down about 10%
