does the apple watch series 2 measure vo2 max and vertical oscillation?

Interesting. Maybe it was an unannounced feature of watchOS 3. I did a little Wikipedia research and it looks like it is an estimate based on workout intensity. Doesn’t kick in until after about 20 minutes of somewhat intense activity in a workout.

I am fairly certain VO2 Max data tracking came with watchOS 4 (even though the heart-rate monitor in the Apple Watch has always been capable).

My understanding is (and I'm no expert) that Sub-Max Exercise Prediction depends on numerous factors, including running surface (hard vs. soft or uneven), hills, wind etc., as these directly affect effort wrt to speed (distance over time).

I haven't seen any papers on how Apple is calculating VO2 Max with the watch and what percent accuracy they may claim, but possibly for more accurate or reliable data, running on a track, with no wind might be the way to go. I hope Apple produces a paper on this so that we can get the best out of this new feature of the watch.

My morning runs are in the woods, on trails, rough terrain, some steep hills and often very slippery surfaces due to a preponderance of rain. When my series 3 arrives, I'm going to do some hard runs on the track to see how much the results vary with those I get in the woods.

Except since I received my Series 3 Apple Watch I’ve had VO2 results in the Health app. So it is either derived from other sources or measured. Very interesting.

My Series 3 won't arrive for another week. But my Series 2 seems to be getting VO2 Max readings and posting them to the Health app.

Hi

The built-in apps do not presently offer any of those features.

Apple has also not announced any those as new features under watchOS 3 / Series 2.
