What is Arginine
Arginine is one of the building blocks of proteins in your body, including your muscles. There are 22 types of amino acids, each with a specific biochemical profile and action. However, arginine is specifically important to athletes who are seeking strength gains and bodybuilders who want to build mass in the muscles. This amino acid has several properties that directly influence the metabolism of your muscles and their gradual growth.
Arginine is a Potent Stimulant of HGH Release
After an intense session of physical exercise, you are tired, your muscles need recovery and repair, and some of the muscle proteins are damaged. The pituitary gland responds to the exercise stimulus by releasing large amounts of Human Growth Hormone (HGH), which has the mission to increase the protein synthesis after physical work. The HGH hormone response to strength training is aimed at replacing the “damaged” proteins in muscle fibers and build new ones, which usually results in muscle recovery, but also muscle growth. Several studies concluded that the amino acid arginine is one of the most powerful stimulants for HGH release. Additional arginine supplementation appears to enhance the HGH response, which normally results in a faster muscle recovery and increased strength due to a more rapid growth of muscle fibers.
Although the main benefit of arginine when it comes to strength gains is related to its HGH stimulation abilities, arginine supplementation may benefit your strength in other ways. This amino acid can stimulate the blood circulation in the muscles through an increased production of nitric oxide (NO), which translates into more muscular strength. Arginine is also implicated in the removal of excessive nitrogen residue from the muscles and liver. Nitrogen is a byproduct of protein breakdown, and it requires a quick elimination from the muscles in order to sustain their functionality during training sessions. Arginine speeds up the elimination of nitrogen-related toxins from your muscles, which allows you to work more effectively during your training.
