V2 Max is probably a remarkable integrator of work so it is not a biomarker that changes quickly and easily to the magnitudes required to do this right

The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
It's that measures like V2 max, just like strength, they're actually integrators of work done. So, um, if a person has a V2 max that is low and their aspiration is to have a very high V2 max, they can, but it will take potentially years and countless hours of work done. And that work will be done at the level of their cardiovascular system, their pulmonary system, their hematologic system, muscular system, metabolic system. All of those things will have to work and work and work for hundreds of hours to get a desired outcome.
