Hormones, definition and description

Hormones are substances produced by certain glands in the body. They are transported through the body by internal liquids, in order to regulate the function of cells and the organs. They perform specific biological functions and enable communication between organs and tissues. With this they regulate bodily functions such as: digestion, breathing, sensory perception, sleep, secretion, formation and development, movement, reproduction, etc. 

The word hormone comes from the Greek word hormon which means “that which sets in motion“.

Hormones regulate everything that happens inside your body. They are the most powerful agents known to science. The whole hormonal system in the body is interrelated. That’s why a change in one hormone means change in all the rest.

It is hormones that direct the body toward building muscle mass, burning fat, strengthening bone density, but also some of them do the opposite. Thus, weight training or exercising can be very precisely defined:

Weight training is a method of regulating and directing the hormones in a desired direction.

That is, increasing those which positively influence the body composition, and lessening those that inhibit the increase of muscle mass, that activate storing excess fat, that “spend” or “eat away” the muscles.

The hormones included here are not described with all of their functions. Described are only some of the positive and negative functions that are of greatest interest to us in regard to building muscle mass and burning off the excess fat. And when we say “a negative characteristic”, it doesn’t mean that those hormones are not necessary for other purposes in the body.

Hormones have a direct and central influence on your physique, structure, body composition (muscle/fat ratio) and aging.

The human body has around 50 hormones. Here we will describe those that are of greatest importance to us in regard to weight training, building muscle mass and losing the excess body fat.

Insulin, definition and role

Insulin is a hormone that is secreted when carbohydrates, i.e sugars are present in the blood.

Testosterone, definition and role
