Oftentimes the nervous system, not the muscular apparatus is the limiting factor in force
production. Tsatsouline stated that “Your muscles already have the strength to lift a car,
they just don’t know it yet” (Tsatsouline, 2000). I agree with that statement and feel that
it’s a good image to help understand the potential improvement in force production by
developing the nervous system.

Let us use Tsatsouline’s example. Feats of strength by apparent weaklings are common.
Just think of the frail middle-aged women who suddenly possess superhuman strength
when her child gets trapped under an automobile or another heavy apparatus. There are
many documented cases in which the woman was actually able to lift the car off the
ground to free her child. A feat that she could not repeat in a million years under normal
circumstances. Sure her strength was potentiated by adrenaline and other hormones, but
the muscles that lifted the car were the same she already had, new muscles didn’t
blossom out of nowhere to help her lift the car! The stress and extreme stimulation from
the situation simply improved her capacity to produce force with the muscles she already
had! Neurotransmission was improved, protective mechanisms were shutdown, sensory
feedback was ignored … All of this made her able to work to her full potential,
something that we don’t come remotely close to doing under regular circumstances.

By now it should be clear to you that the limit in force production lies in the nervous
system. The greater the proportion of his strength potential an athlete can use is, the
better he’ll be. The difference between absolute strength (the full potential for strength
production) and limit strength (the actual maximum strength that an individual can
voluntarily produce) is termed the strength deficit.
