Slow-twitch (Type I) muscle fibers exhibit 5-6 times less power than Type IIa fast-twitch fibers, and Type IIx fast-twitch fibers exhibit up to 20 times less power than Type I fibers when normalized for size.

“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 2 a so that's a fast twitch muscle fiber um you're going to see something like 5 to 6X power between these two so it's not when you normalize for size you normalize for cross if you go if you go to the two x fibers which is a special class of fast switch fibers now you're talking 20x that power curve”
