Detailed explanation-1: -Type IIb (fast-twitch glycolytic) fibres use anaerobic metabolism to generate energy and therefore do not require oxygen as an energy fuel. They are predominantly used in fast and powerful bursts during sports such as a 100m sprint.
Detailed explanation-2: -Type IIx are best known as fast-twitch muscle fibers. These are the muscle fibers primarily responsible for fast, explosive movements like sprinting.
Detailed explanation-3: -Activities like sprinting and weightlifting rely on fast twitch muscle fibers due to high levels of intensity and shorter work periods. These fibers contract faster, allowing them to produce greater amounts of force, power, and strength, but they fatigue faster.
Detailed explanation-4: -FG fibers are used to produce rapid, forceful contractions to make quick, powerful movements. These fibers fatigue quickly, permitting them to only be used for short periods.
Detailed explanation-5: -sprinting. powerlifting. jumping. strength training. agility training. high-intensity cycling. high-intensity interval training (HIIT) 14-Jan-2020
