A muscle's slow release of a contraction. -Contract -Eccentric Contraction -Nerve -Microtear -Progressive Resistance

The correct option is;

-Eccentric Contraction

Explanation:

The releasing of the muscles slowly to become longer under the effect of a load is known as eccentric contraction

An example of eccentric contraction is the elongation of the curl biceps as the load of the dumbbell is lowered down after lifting, such that while in the process of lowering rather than dropping the dumbbell down the biceps remain in contraction so as to maintain control of the descent

Along with eccentric contraction, isometric contraction and concentric contraction make up the three  phases of muscles and tendon movement.
