What type of muscule tires quickly during exercise?
A doctor has provided 1 answer
Muscle 101: We have three types of muscles: skeletal, cardiac, and smooth. We have no conscious control of the latter two muscle types. Skeletal muscle is considered voluntary muscle. It is composed of slow twitch and fast twitch fibers. Slow twitch fibers contract for long periods with little force while fast twitch fibers contract quickly with power and fatigue quickly. Your answer: fast twitch skeletal.
