VO2max not working?

Former Member over 5 years ago

A six weeks ago I got out of the hospital after lung problems (no not this nasty virus). Since then I have been hiking often and now started running. My SpO2 has been improving. However my VO2max has been decreasing. I do not get why this would be happening. My health improves and my VO2max is dropping. During the last two weeks the VO2max has not changed.

How is the VO2max calculated on this device?

VO2max is very buggy. It's not updating when I'm cycling or MTBing for hours. But it's updating if I track short walk to the grocery shop?! Months ago, it was working fine for cycling, MTBing, cardio workouts in the gym...
