Vo2 max from garmin

[grwoolf]

I’ve had vo2max lab testing a couple times and the garmin is reasonably close for me. I can’t remember how close it was for my first test, but it was about 2 ml/kg/min high for me compared to my latest lab test. I assume the garmin algorithms are done based on correlating factors across a chosen population, so it makes sense that they might get pretty close when comparing results in aggregate across a similar population. I couldn’t find the .3 accuracy reference in that linked article, but I didn’t look too hard. I can’t believe they would be only .3 off for many individuals, so I’m assume is aggregate.
