Detailed explanation-1: -Extraocular muscles are among the fastest and most fatigue-resistant skeletal muscles. Their highly specialized function, to move a sensory organ, the eyeball, is reflected in their specific MHC content and the multiplicity of fiber types.
Detailed explanation-2: -Fast-twitch muscles are a large proportion of the small muscles in hands and eyes for rapid movement. There are two subcategories of fast-twitch muscle fibers: Type IIA and Type IIB or Type IIX.
Detailed explanation-3: -The chest muscles, triceps/biceps, and hamstrings are more fast-twitch. Shoulders, forearms, and calves, however, are more slow-twitch, while quads and back muscles tend to be a mix. To train fast-twitch muscles, weight lift with lower reps (5-7) and more weight.
Detailed explanation-4: -Fast-twitch muscle fibers give short but powerful bursts of energy, which makes them essential for activities like sprinting and jumping. Slow-twitch muscle fibers are used for endurance activities, such as long-distance running or cycling.
