The “V” in VO2 max stands for volume. It is measured in liters in step with minute (L/min): the quantity of oxygen you breathe in a minute. But Apple uses a barely greater complicated metric: mL/(kg·min). In that manner, milliliters of oxygen in line with kilogram of body mass according to minute. Taking your frame weight into consideration makes the stat more comparable between different human beings because a bigger man or woman is more likely to consume extra oxygen than a smaller man or woman.
The “max” in the VO2 max way the measurement needs to be taken while you are running out at your maximum level of exertion when you are giving it the whole lot you’ve got.
Why is VO2 max exciting?
The key to being right at patience sports is the potential to preserve a high depth of attempt for a long period. Running fast for a few yards is all very well, but that isn’t always going to be enough if you are training for a marathon.
The purpose you may’t preserve your quickest tempo for terribly long is due to the fact tbecauseuse of exceptional strength structures to gas exceptional degrees of workout intensity.

To us, it should be, degree your VO2 max; you must wear a face mask. This is the simplest way to understand for positive how lots of oxygen is going in and out of your lungs.
Since Apple Watch is worn on your wrist, not your face, that is out of the question. So instead, Apple Watch affords a “predicted VO2 max” metric. This is an estimate based on changes to your heart rate at some stage in a workout.
Are VO2 max predictions accurate?
The relationship between coronary heart rate and VO2 max isn’t precise, and it varies from one character to another. So Apple’s predicted VO2 max might not be very accurate. The estimate is also structured upon your Apple Watch’s coronary heart rate sensor. And at the same time, as that’s pretty suitable, it is not infallible.
