the big characteristic difference at least in young people is that the size of the fiber is just distinctly different

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

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.
the type two fibers so for example type 2x those typically are bigger they're typically stronger but they fatigue much faster the type 2a it's a little bit more oxidative they're pretty forceful and you can they can sustain it for quite some time
the perhaps the overall just size difference whether or not there are other things whether how how it may interact and and the the speed of it that might be different as well
what you're going to see is a true slow twitch so these are also called type one fibers um if you compare those to a type 2A so that's a fast twitch muscle fiber um you're going to see something like five to 6X power between these two so it's not when you normalize for size Norm for cross if you go if you go to the 2x fibers which is a special class of fast fibers now you're talking 20x that power curve
