Vo2 Max is stuck at 39 and doesn’t change at all, i do sufficiently zone 3 and zone 4 training, i have even changed gps settings but there is no capture of vo2 max.

    For running, garmin uses an algorithm that mainly looks at interval training. Do interval traing and make sure you rest enough between the intervals that your heart rate drops significantly and your vo2max will skyrocket. Do a lot of ‘easy’ long runs and your vo2max will plummet.

    For biking the algorithm is just plain wrong. I don’t bike that much and use it mainly for recovery trainings. But garmin thinks my vo2max is a whopping 71.

    Vo2 calculations of garmin (like more of their algorithms) aren’t very good, although garmin marketing suggests they are very scientific.

    Hi ! 

    Please see  My Recorded Activity Did Not Update the VO2 Max Estimate and What Is VO2 Max Estimate and How Does It Work?. If you have any further questions or need further assistance, please reach out to Garmin Product Support directly so one of our agents can take a closer look into your account. Thank you!

    This is not correct. It can be what you are seeing, but this is not the way it works at all. Your case may not be isolated, but it is doesn't apply to others like me. I don't know what skyrocket or plummet really means.

    Check your Max HR, that would make your biking VO2 Max. If your biking VO2 Max is awfully wrong, it could be a sign that your power data is wrong. My biking VO2 Max matches my running VO2 Max better when my Max HR is accurate.

    Firstbeat white paper states that the accuracy is excellent for sport sciences: a few percentage points of standard mean error. Various scientific studies have estimated that the standard mean error could be around 8%.

    Since the method is predictable and reproducible, your trends in VO2 Max are what matters. Everybody can drive a car and run out of gas with notoriously inaccurate gas tank gauges.

    If you need more accuracy for your training for some reason, you should do a test lab.

    Glad you asked. I do regularly tests at a sport medical center.

    Even using coopertests is closer to a test in a sport medical center than garmins calculations.

    Agree! Doing Cooper I'm about 42. Coros have me at 39-40. Runalyze (non-adjusted) Effective VO2max was at 42 before my last break. Garmin... they normally have me at 50 and even up to 51. Has been like that with FR620, FR630, Fenix5X and FR955. FirstBeat running algos simply do NOT work with my body. Period. The End! I'm 64 years old and have been running 11 years. Prior to that I was a couch potato for 35 years - smoker and wet snuff user for all that time. Between 11 years of age and 18 I was a swimmer with sprint speciality - max 100 meters (quite good - region Nr2 in my age category) but at school 'Phys Ed' I was at the back - with the 'fat kid' - whenever we did ANY running activity. My natural VO2Max seems to be low. Which is fine... I run for the running itself.

    great you share your experiences.

    But for some garmin is the goal, everything else you’re not allowed to talk about ;)
