WebApr 6, 2024 · 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 much oxygen.
