WebbAboutTranscript. Type 1 and type 2 muscle fibers differ in a few key ways. Type 1 (“slow twitch”) fibers contain more mitochondria, which means they can produce more energy and are better for long, aerobic activities. Type 2 (“fast twitch”) fibers, on the other hand, are suited for short, fast bursts of activity that don't require as ... Webb11 nov. 2011 · Weightlifters and powerlifters have muscle fiber areas composed of roughly 2/3 type II fibers and 1/3 type I fibers. In bodybuilders it's the other way around: 2/3 of their muscles' cross-sectional area comprises slow twitch and only 1/3 of it is fast twitch.
