Well, when you come back the next time to do that run, you've built endurance largely because you've built these capillary beds. You've expanded these little streams in which blood can deliver oxygen to the muscles.

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.

And the type of long duration effort that I was talking about before to 12 minutes or more of steady effort is very useful for doing that, and is very useful for increasing the mitochondria, the energy producing elements of the cells, the actual muscle cells.
The type of long-duration effort that I was talking about before, 12 minutes or more of steady effort, is very useful for doing that, and is very useful for increasing the mitochondria, the energy-producing elements of the cells, the actual muscle cells. The reason is when blood arrives to muscles, it has oxygen, the muscles are going to use some of that oxygen, and then some of the deoxygenated blood is going to be sent back to the heart and to the lungs. Now, the more capillaries that you build into those muscles, the more oxygen available to those muscles.
