Aliment Sports Nutrition: proteins

Among so many changes, tips and fashions, we often do not know what part of what is read or studied turns out to be the right thing to do. The idea of this post is to guide you about the importance and function of proteins in our body.

To begin with, what are proteins? As it is – no more nor less – of essential molecules necessary for the proper functioning of our body and the basic element of construction of the tissues that make up our body and also regulate numerous vital functions. Proteins are made up of smaller units called amino acids. There are 20 different types of amino acids, eight of which we have to ingest with food, because we are unable to synthesize them, so these eight amino acids are called essential. Depending on the type of amino acids a protein contains, they can be classified into:
Proteins of high biological value: Contain the 8 essential amino acids. We can find these proteins in foods of animal origin like meat, fish, eggs and dairy.

Proteins of low biological value: Do not contain all the essential amino acids. They are found in foods of plant origin such as cereals, legumes, vegetables and fruits.

Here are your main functions:

Enzymatic function: regulate all chemical reactions of the organism, there are about a thousand.

Structural function: they are components of different parts of the body. They are part of cell membranes, collagen fibers, elastic fibers, keratin of the skin, hair and nails etc.

Transport function: transport vital substances through the body like hemoglobin, which carries oxygen in the blood.

Regulatory function: They act like hormones that regulate diverse physiological processes; Control growth and development (growth hormone, insulin, etc.); As neurotransmitters mediating responses of the nervous system.

Contractile Function: Actin and myosin are proteins found in muscle cells forming fibrils that allow muscle contraction and relaxation.

Defense function: The most important are immunoglobulins (antibodies).

Finally, what are the famous hyperproteic diets for athletes? Usually the same question arises, do proteins increase at the expense of carbohydrates or fats?

Many times the percentage of proteins is increased at the expense of carbohydrates, but in athletes who are active this tactic is not the most opportune. An energy restriction (diet) affects carbohydrate stores, and this should be avoided to maintain tolerance to training, particularly in sports with high physical demands. Proteins should be balanced with both hydrates and fats or with fats only.
