Slow vs fast muscle fibers
WebbSlow twitch fibers are used for activities that require sustained effort, such as long-distance running or cycling. They use oxidative phosphorylation for obtaining ATP. On the flip side, fast-twitch fibers have a high power output and tire quickly. They contain fewer mitochondria and blood vessels and rely on stored glycogen as a fuel source.
