Explanation:
Detailed explanation-1: -Type IIa fibers, or fast oxidative glycolytic (FOG) fibers, present higher twitch speeds than type I fibers but are less fatigue resistant. Type IIx fibers, or fast glycolytic fibers, possess the fastest twitch speeds but are highly fatigable [1].
Detailed explanation-2: -Fast-twitch fibers are called “white fibers” because do not contain much blood, which gives them a lighter appearance than slow-twitch fibers.
Detailed explanation-3: -Type II muscle fiber is also known as fast twitch muscle fiber.
