Type ii b fast-twitch muscle fibers are those used in a short sprint true or false.

Type II B fast-twitch muscle fibers are those used in a short sprint. This statement is true.

Further Explanation:

Skeletal muscles are composed of muscle fibers. The muscle fibers are different like muscles are different. There are two kind of skeletal muscle fibers are:

Both the muscle fiber have different role in exercise and movement. Functions of Slow-twitch muscle fibers are

Slow-twitch fibers sometime referred as red fiber or type-I fiber. They called as red fiber because they allow supply of blood. They consists myoglobine and mitochondria. The fast-twitch fiber also called as type-II fiber provides more force than slow twitch fiber. They also have a drawback that they provide more force for only short duration and they fatigue rapidly. They are aerobic as compare to other muscle fiber and supply blood in a very low amount. That’s why they referred as white fiber. They help in supporting powerful quick, movements like weightlifting and sprinting. The fast-twitch fiber also divides into type-IIA and type-IIX. The type-IIX also referred as type-IIB and provides more force. Thus, in sprinting type-IIB muscle fibers are used.
