Type II fibers, also known as fast-twitch muscle fibers, are specialized muscle fibers that are designed for quick bursts of speed and power. These fibers are less efficient at using oxygen compared to Type I fibers, making them more suited for anaerobic activities like sprinting and weightlifting. They fatigue more quickly than their slow-twitch counterparts, which has important implications for muscle metabolism and overall physical performance.
congrats on reading the definition of Type II Fibers. now let's actually learn it.
