VO2 max on treadmill

over 2 years ago

I believe  VO2 max is calculated only with GPS data.

However, I have  "RUNN" smart sensor (https://npe-inc.com/runn-smart-treadmill-sensor-2/) attached to the treadmill to show accurate pace and distance data. This, along with HR data, should be enough for VO2max

Is there an option (or can it be implemented) to use smart sensor to  calculate VO2MAX data?

Thanks

    I noticed with " Lactate Threshold Measurement" the watch requires GPS and HR belt to work.

    However..if I switched the GPS on (RUN activity) the watch entered the test while the speed was still coming from the smart sensor (the RUNN)

    I'm just wondering...if the VO2max could be calculated with the same setup. I will test this later...

    Yes it should be an option to calculate VO2 on treadmill after the user confirms the distance and inclination. 

    If fact, laboratory tests are made on treadmills.

    I can confirm VO2 max result can be calculated on treadmill.
    I set the activity to RUN and chose from "Sensors& Accessories" the FP sensor (FP as Foot Pod??) and changed the speed and Distance from Indoor to  Always  

    Previously it was set to "Indoor". My fist attempt on " Lactate Threshold Measurement" failed since...after the GPS signal was detected..the watch started to count distance based on weak GPS singal (indoors) and the reading was abviously way off

    However, once I changed to "Always" I started to get consistent speed and distance readings. On 3k test run I got a new VO2max value...althoug it dropped a bit. But next time I can run flat out to get it back were it belongs...to 54-56:)

    Nice workaround! 

    But did the distance calculate correct matching the treadmill distance? 

    Did you find an option to correct / calibrate it if not?

    Calibration is possible if you have set to „indoor”, with settings to „always”, callibration is switched off.
    Than first you should do calibration to be sure distance is calculated correctly and than you could do the switch.
    Otherwise, you will never know, was it calculated correctly.

    To clarify, you turned on GPS *and* set the foot pod to "always" distance *and* pace?

    It should not be necessary, since the watch uses the accelerometer estimation, or the external sensor, whenever the GNSS (GPS) accuracy is not sufficient. That happens also during normal outdoor runs, whenever the GPS signal drops out (underpasses, dense vegetation, urban jungle, ... and in other similar conditions). Even if the HRM-Pro is set to provide the pace and distance data only indoors, it should be fully sufficient. The watch switches to the indoors mode instantly when the GPS signal is insufficient.

    I think the idea is that Garmin won't use indoor runs as a source of VO2 Max, regardless of the fact that speed is still available from the accelerometer or footpod. That's why the workaround is turn on GPS even though you're running indoors.

    Running VO2 Max Estimates

    For most Running and Outdoor watches , the activity must be recorded using the Run activity profile.

    • Running activity must be 10 minutes or longer.

    • Activity must be recorded outdoors with a GPS signal.

    • Heart rate data from a built-in optical heart rate sensor or from a chest strap.

    • Heart rate must be elevated to at least 70% of your maximum heart rate for at least 10 minutes continuously.

    ...

    VO2 Max Estimates Without GPS

    This method only applies to compatible watches that do not feature an internal GPS receiver.

    ...

    VO2 Max Estimates From All-Day Heart Rate

    Watches announced after April 2017 that feature an optical heart rate monitor are capable of generating VO2 max from all-day heart rate data. VO2 max generated from all-day heart rate will only show if you have not generated VO2 max from another source above, unless the all-day heart rate VO2 max is better than VO2 max generated from other sources.
