My VO2 MAX hasn’t updated since June 16th, I think which was around the time of the last update on iOS mobile. I walk 3 to 4 times a week and it usually updates almost every time I walk.
Anyone else have that problem?
Check out the document My Recorded Activity Did Not Update My VO2 Max Estimate
It tells about the walking VO₂max:
Walking VO2 Max Estimate
The Walk activity must be 10 minutes or longer.
- On a vivosport, it must be 15 minutes or longer.
The activity must be recorded outdoors with a GPS signal.
Heart rate data must be recorded (from either a built-in optical heart rate sensor or from a chest strap).
Your heart rate must be elevated to at least 70% of your maximum heart rate for at least 10 minutes continuously.
On a vivosport, it must be 15 minutes continuously or longer.
From that document -
The Bike activity must be 20 minutes or longer without stopping.
Heart rate data must be recorded (from either a built-in optical heart rate sensor or from a chest strap).
Your heart rate must be elevated to at least 70% of your maximum heart rate for at least 20 minutes continuously.
A power meter is required.
I do not have a Power meter and it updates my VO2 Max
