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. Webb20 jan. 2024 · Slow-twitch fibers are fatigue-resistant, long-haul muscles that are aerobic (oxygen-reliant). Fast-twitch fibers reach exhaustion more quickly but are also the …
