What is BCAA?
Proteins are made up of amino acids. These are divided into different groups based on their chemical structure. The proteinogenic amino acids leucine, isoleucine and valine have a branched side chain, which is why they are grouped together as branched-chain amino acids. Instead of this somewhat unwieldy name, the English abbreviation BCAA (branched chain amino acids) is often used. BCAA are among the essential amino acids that your body cannot produce itself. You therefore have to get them through food.

Where are BCAAs found in the body?
The largest reservoir of branched-chain amino acids is skeletal muscle. There they are mainly found as a component of muscle proteins. BCAA are found in animal protein in a ratio of 2:1:1 (leucine: isoleucine: valine). The BCAA concentration in blood plasma is also quite high compared to other amino acids (with the exception of glutamine). Since they can cross the blood-brain barrier with the help of a transport system, the branched-chain amino acids can also be found in the brain.

How do BCAAs get into the muscles?
BCAAs are absorbed in the intestines through the intestinal mucosa. They reach their target tissues directly through the blood as free amino acids, without being broken down or converted in the liver like other amino acids. About 70 percent of the increase in free amino acids in the blood plasma after a meal is due to BCAA. Once in the target tissues, they take on important metabolic functions.

BCAA in sports
The results of numerous scientific studies indicate that BCAAs both stimulate muscle growth and inhibit muscle breakdown. This makes BCAA very popular in weight training and bodybuilding. According to studies, BCAAs stimulate muscle building by increasing the amount of glutamine in the muscle, which the body takes as a signal to build more muscle. The inhibition of muscle breakdown occurs via branched-chain keto acids (amino acid metabolism products), which are created by the breakdown of BCAA.

BCAA are also useful in endurance sports. They apparently lead to a reduction in fatigue during muscle work. The brain messenger serotonin is responsible for the exhaustion processes that occur during physical exertion. Serotonin is made from tryptophan in the brain. Tryptophan competes with branched-chain amino acids for the same transport mechanism into the brain. If there are many BCAAs in the blood after consumption, these are primarily absorbed into the brain instead of tryptophan, which inhibits serotonin production. According to this theory, less serotonin also means less fatigue.

What else do BCAAs do?

If you train intensively, this can lead to overloading of bones, tendons and joints, especially at the beginning if your muscles are weak. Fortunately, the muscle protection provided by BCAAs does not seem to be limited to inhibiting muscle breakdown. BCAAs also appear to be able to prevent muscle soreness and muscle damage, as shown in a study of untrained young men who completed 90 minutes of endurance exercise.
