A LITTLE PHYSIOLOGY IN YOUR HEADS
Many exercisers wonder why someone looks like a “bull” and someone looks like a “skinny deer”.
Even though they both work out equally hard at the gym?
In order to influence the process of muscle growth, you have to know the physiology, to organize your training and rest properly.
So, remember, gentlemen:
Our muscles are made up of slowly contracting and rapidly contracting fibers.
We already know (from the last post) that muscles do not grow when a workout takes place, but after it.
During a workout, muscles get injured, strained and partially torn. After exercise there is a recovery process -> and it is in the recovery process that muscle growth occurs.
It is simple: healthy cells replace the damaged ones in higher numbers.
When you work out at the gym, you are training the muscles of the skeleton, which are made up of myofibrils. They form the muscle fiber.
A person has 650 skeletal muscles. They contract when there is a command from motor neurons.
Through nerve impulses, motor neurons “tell” the muscles to contract.
As a result, the better this connection is established, the more active the contraction of the muscle fibers is.
Here’s an interesting fact:
A person’s physical strength does not depend on muscle volume and mass, but on the body’s ability to stimulate motor neurons and to better contract muscle fibers.
