How accurate is the V02 max on a GPS watch? I have a Garmin Vivoactive 3 that displays V02 max. The V02 max number tends to go down when I have a super easy day or low mileage week, and it goes up when I have a more intense week of training. Should I ignore this stat or pay attention to it?
I found a loophole, namely that if you wear two Vivoactives simultaneously, you can nearly double your VO2Max. I call it my Vivo2Max.
I wonder if anyone can tell me if they think V02 Max is an accurate measure in a lab? I struggled running in a treadmill to max effort as i was worried about slipping on the treadmill and hurting myself. Also it was inside so i was hotter than i would ever be on the track. So while i agree the Garmin is not accurate i would also question my own personal Lab V02 Max scores accuracy

I would say that this is the dumbest thing I've read on this board - but I'd be lying. There are quite a few that are worse. This one is high on that list.
... especially because of the strong relationship between VO2 max and longevity among the elderly.
Can you provide some more details on this?
I'm not sure which studies and researchers are the most reliable sources, but if you simply google the words VO2 max longevity, you will get many articles on this subject, including some that have concluded that VO2 max is the best predictor of longevity available. VO2 max in the elderly typically decreases to extremely low levels, to the point that oxygen uptake is insufficient to deliver oxygen to vital organs and insufficient to deliver oxygen that can handle even modest changes in metabolism, as might be required for walking or anything else much more metabolically intense than lying in bed. There's something of a snowball effect, in which decreased VO2 max limits metabolically more intense activities, which in turn results in muscle atrophy, bone loss, poorer heart and circulatory health, and ultimately an inability to sustain basal metabolic rates needed to sustain life. These changes are likely inevitable if you live long enough, but you can start from a relatively high VO2 max and slow down the rate of decrease. thereafter.
