Question

When one is performing a box-to-box plyometric drop jump, in order to generate sufficient force in a limited amount of time (< 200 ms), which muscle fibers are bypassed through the principle of selective recruitment?

Answer 1

Answer:

Muscle Fibers Type I

Explanation:

Muscle fibers in the body are classified based on how they produce energy or generate force. The  Muscle Fibers type I, type I C, type IIC, type IIAC, type IIA, type IIA and type IIX are generally classified as being either slow-twitch or fast-twitch.

Muscle Fibers Type I is generally a slow twitch fiber. They can provide their own source of energy and can sustain force for an extended period of time, but they are not able to generate a significant amount of force.

However, the activation threshold is quite low, this means that while they get recruited first when a muscle contracts, they are unable to generate the amount of force necessary for the specific activity. They are, therefore, bypassed through the principle of selective recruitment and the fast-twitch muscle fibers are engaged.
