Strength of muscle work

To raise the strength of muscle work is the muscle contraction intensely raised?

E

Expert

Verified

A raise in the strength of muscle work is not attained by rise in the intensity of stimulation of each muscle fiber. The muscle fiber follows an all-or-nothing rule, that is, its contraction strength is just one and can’t be increased.

Whenever the body requires increasing the strength of the muscle work a phenomenon termed as spatial summation takes place: new muscle fibers are recruited in addition to fibers already in action. Therefore the strength of muscle contraction rises only whenever the number of active muscle cells rises.
