Question

muscular strength exercises such as sprinting and power lifting use which type of muscle fibers?
endurance
slow twitch
involuntary
fast twitch

Explanation:

Muscular strength exercises like sprinting and power lifting rely on fast - twitch muscle fibers. Fast - twitch fibers are better at producing quick, powerful contractions, which are needed in these high - intensity, short - duration activities. Slow - twitch fibers are for endurance, involuntary muscles are not related to this type of voluntary, strength - based muscle action, and “endurance” is not a type of muscle fiber.

Answer:

D. fast twitch (assuming the options are labeled A: endurance, B: slow twitch, C: involuntary, D: fast twitch. If the original options don't have labels, then the correct option is the one with "fast twitch")
