Question

Performing Olympic style lifting causing a maximum contraction against a sub-maximal resistance, and forcing the recruitment of fast twitch fibers, is ___________ type of motor unit recruitment.

Answer 1

Answer:

Type IIA- Fast twitch, fatigue resistant unit

Explanation:

During intense activities such as exercises where there is an increase in the  contractile muscle strength, there is an activation of additional muscles to accomplish the task.

This is referred as motor unit recruitment.

It can be type I where it involves slow twitch fatigue resistant units with small twitch tension and slowest contraction

Or Type II A- where fast twitch, fatigue resistant fibers are activated to enable a larger force and faster contraction.
