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.
