Branched-Chain Amino Acids Prevent Muscle Fatigue and Speed Up Recovery After Exercise

Branched-chain amino acid (BCAA) is the collective name given to the three essential amino acids out of the nine, that are key components in the production of proteins -- leucine, isoleucine and valine. They are called branched-chain amino acids because of the unique "branch" found near the main trunk of the amino acid molecule.Leucine, isoleucine and valine account for 35 percent of the protein content found in the human muscles. Some weightlifters believe that taking BCAA supplement increases muscle mass much more than eating foods rich in proteins but less in BCAA.Among the three branched chain amino acids, leucine is most effective in stimulating the secretion of insulin from the pancreas responsible for regulating fat and carbohydrate metabolism in the body. It has the ability to lower blood sugar levels and plays a key role in the production of human growth hormones.Leucine works in harmony with isoleucine and valine to promote the healing of damaged or injured bones, skin and muscle tissues, thus often recommended especially for patients recovering from surgery. However, excessive dose of leucine may cause pellagra, a disease caused by a deficiency in niacin or vitamin B3 in the diet, and may also increase ammonia levels in the body.You can be assured of speedy recovery from damaged and injured muscle tissues, skin and bones by eating foods rich in leucine such as pork, beef, chicken, brown rice, nuts, soy, beans, and food items made of whole wheat and flour.Isoleucine's unique role is to regulate the body's blood sugar and energy levels. It is also an important component in the production of hemoglobin, the component of blood that contains iron and is responsible for transporting oxygen from the lungs to the different parts of the body.When taken in combination with leucine and valine, isoleucine is reinforced to improve the body's energy levels, increase endurance and stamina and aid in the healing and repair of muscle tissues after extreme physical exertion making it a valuable nutrition supplement for high-performing athletes and bodybuilders.Many mental and physical disorders have been found to be associated with isoleucine deficiency, which can lead to symptoms similar to those of hypoglycemia, a condition where blood sugar levels are lower than normal.You can improve and maintain sound mental health and increase physical strength and stamina by eating foods rich in isoleucine such as meat, fish, chicken, eggs, rye, cashew nuts, chickpeas, lentils, soy protein and most seeds.Valine is the third member of the branched chain amino acids. Like leucine and isoleucine it also aids in muscle metabolism and the repair of damaged and injured tissues of the body.Valine's unique characteristic is its ability to aid in the maintenance of the body's proper nitrogen balance. It is also considered a good option for treating certain liver and gallbladder diseases, and certain types of amino acid deficiencies caused by drug addiction.However, an overdose of valine can lead to symptoms of a crawling sensation in the skin and may even cause hallucinations.Deficiency of these three amino acids is believed to cause Maple Syrup Urine Disease. When the body lacks the alpha-keto hydrogenase complex, leucine, isoleucine and valine and their toxic by products start to accumulate in the blood and urine giving the urine a sweet taste and a distinct smell similar to that of maple syrup, thus the term Maple Syrup Urine Disease.
