WebbThe amount of force needed to be produced determines the activation of muscle fibers: slow twitch fibers are recruited by the nervous system first till they are overwhelmed. WebbSlow-twitch fibers are also smaller in diameter than fast-twitch fibers and have increased capillary blood flow around them. Because they have a smaller diameter and an increased blood flow, the slow-twitch fibers are able to deliver more oxygen and remove more waste products from the muscle fibers (which decreases their "fatigability"). list of submarine pitchersWebb10 sep. 2024 · fast-twitch muscle fibers, which help you move faster, but for shorter periods “Twitch” refers to the contraction, or how quickly and often the muscle moves.
