Central Nervous System

Central Nervous System While muscle growth is the endless target of fad products and men magazines, the central nervous system is often neglected, even though it plays an equally important role in strength and performance. Remember the science lesson we had earlier? The motor neurons are what give the signal and stimulate the muscle cells to contract. Contrary to popular belief, the nervous system plays an extremely important role in strength

and performance, on par with the actual muscles themselves. The central nervous system is heavily taxed whenever large loads are moved or near-maximal exertion is achieved. It's important to allow a day or two of rest between days when the CNS is heavily taxed to allow it to recover. It doesn't grow in the same sense that muscles do but rather gets stronger. Motor patterns are also ingrained in your nervous system. The maxim (perfect) practice makes perfect is true!
If you repeatedly do a specific movement, the neurons responsible for that movement will strengthen and that path will be remembered; this is the phenomenon known as muscle memory. For example, if you deadlift a lot your brain will have a neuron path dedicated to the muscle movements associated with deadlifts, then when you pick up a heavy box off the floor that neuron path will be remembered and you'll automatically assume a deadlift position. This can be highly beneficial in most sports,
when a specific movement has to be repeated multiple times accurately.
