VO2 Max Calculations - changes each ride???

Hi All, does anybody here make use of the 1030 VO2 Max calculations?  I ride and run; my run VO2 Max is calculated by my watch; and my bike VO2 Max is calculated by my 1030.  Obviously VO2 Max changes reasonably slowly overtime and day to day changes are small.  Changes over a week or two are definitely possible but not really day to day.  I use WKO/TrainingPeaks  to actually monitor VO2 and this week compared it with laboratory data and TrainingPeaks was spot on.

What happens with my 1030 however is quite strange.  My VO2Max number goes up and down significantly based on the last ride activity I log.  I might get 53 on a Monday when I do VO2Max intervals; but it might be as low as 50 on a day when I do a short muscle endurance ride; or even 49 if I do an easy recovery ride - all within the same week.  

While the numbers are in the ballpark with the laboratory result; it appears the 1030 places much more emphasis on the last completed ride, rather than considering a weeks worth of rides etc.  Clearly a recovery ride isn't going to get anything close to VO2 Max and therefore shouldn't be used to generate a new VO2Max score.

My running VO2 Max doesn't show anything like the same level of variation.  Slow recovery runs don't reduce it, hard intervals don't suddenly affect it - the graph shows a much more steady progression.

Is anybody else experiencing the same thing - do people use VO2Max?

TIA

  • my running vo2max (FR945) and cycling vo2max (Edge 830) mostly jump, but only 1 down or up, not so extrem as for you, your hr zones have so big difference between running and cycling?

    wko5 shows vo2max too, what values you got there?

    i tried only a trial of wko5, but it shows me a better vo2max for running as garmin and cycling vo2max was nearly the same as in Garmin

  • My running vo2max (Marq) functions like it should and sounds like you are having the same experience with your 945.  

    WKO5 is excellent and actually modelled my vo2max the same as the lab testing I did yesterday. on that basis alone wko5 is worth exploring but it’s real value is in the power curve and training different energy systems. 

    The 1030 just doesn’t work in the same way. The vo2max numbers are high; and they can change with every ride. It trends in the right direction but the constant changes are really annoying as it is on my watch face. I hate being downgraded when I do a recovery ride :). 

  • I see similar, and suspect the issue is sync / correlation related between devices.

    I go between three Garmin devices: a Vivosmart 4 I wear nearly all the time (unless I'm doing sport when it goes on charge), a fenix 5 Plus for most activities, and an Edge 1030 for cycling. In theory this covers me 24/7 and should give good results especially with the Garmin "Tru-Up" feature.. in practice I don't think it works too well.

    The best I've seen is when I've been on sports-related weeks away and where I've worn/used solely my fenix 5 Plus - all the metrics seem to then track correctly. I've had to disable the auto activity recording on my Vivosmart 4 (walking, ad-hoc town cycling etc) as this severally messed up my VO2 max (so now this devices is basically a step counter / all-day HR monitor / sleep tracker); and like your experience once the Edge 1030 gets involved this too can seemingly confuse things again especially in terms of VO2 max (and despite cycling VO2 max being recorded separately).

    While seemingly a bigger issue, I'd either like: a) all metrics to be governed centrally on the Garmin Connect platform, or, failing that, b) to be able to nominate which device takes charge for different things (eg. Edge 1030 to take the lead for all things cycling, others to have input only).

    Disappointing, especially as, at the time at least, these three devices were the flagship Garmin offerings for each category.

  • Ok, so lots of us with the same issues; does anybody have a cycling vo2max from a 1030 which does not go up and down based on the intensity of their last ride??

  • i am not 100% sure if it is worth 200 EUR, on my Windows PC it's a little bit slow, but i have a good machine, think on mac it runs more liquid.
    Hope there will come a discount some day, black friday or so, then i think i will buy it 

  • Good plan.  If you like data you will definitely like WKO.  Just be prepared to do some learning because it is a rabbit hole - in a good way Slight smile
