Recruitment

Explanation:

A motor unit is made up of a motor neurone and all the muscle fibre it supplies nerve to.

Within a muscle, the muscle fibers are functionally organized as MOTOR UNITS within a muscle.

MOTOR RECRUITMENT causes an increase in muscle tension which occurs when there is an increased number of stimulated motor units.

During a muscle contraction, the weakest motor units are recruited to contract first,The more weight (resistance) you add to a muscle, the more motor units you will need to recruit in order to generate movement.Recruitment stops as soon as movement starts, result is a smooth, even muscle contraction. I hope this helps, thanks.
