The answer is <u>"B. type II B fast-twitch muscle fibers that respond quickly and provide her with speed and strength".</u>
Fast-twitch muscles separate into two classes: moderate fast-twitch (type IIa) and fast-twitch (type IIb or IIx). Moderate fast-twitch muscles are thicker, faster to contract, and destroy more quickly than slow-twitch. Fast-twitch, the most ground-breaking and least in continuance, are initiated when the body nears greatest effort.
Here's the means by which it works: During aerobic activities, for example, running or swimming, slow-twitch fibers are the first to contract. At the point when the slow-twitch fibers wind up drained, fast-twitch fibers start to assume control.
