"Webb16 okt. 2024 · They naturally produce less force, so they are slower to produce maximum tension. Because they don’t explode up front, they can remain stable for a long time and don’t fatigue as quickly. Slow-twitch fibers are also smaller in size. That’s why marathon runners or endurance athletes have longer, leaner muscles compared to weight lifters. " - Slow muscle fibers vs fast muscle fibers
