Branched Chain Amino Acids On Sports Performance

1197 Words3 Pages

With sportsmen seeking alternatives to illegal and unsafe performance enhancing drugs, “ergogenic aids” have come to their rescue. Ergogenic aids are supplements that enhance the performance of athletes by improving their speed, strength and agility. A number of natural products are marketed as ergogenic aids, which have found a ready market among sportspersons. Their biggest advantage is that they are legal, apart from being safe and effective. Examples of such aids include branched chain amino acids, creatine, medium chain triglycerides, pyruvates and vitamins.

I. What are Branched chain amino acids?

Branched chain amino acids (BCAA) are amino acids whose molecular structure is made up of branched aliphatic side chains. Three amino acids occurring in humans, viz. valine, leucine and isoleucine, are essential BCAAs. They are essential because they are not synthesized by the body and have to be supplied through diet. Amino acids are the building blocks of proteins, which in turn, are the building blocks of the body. A high proportion of muscle tissue is built of BCAAs. Therefore, these are of high utility in increasing muscle mass, especially for those who undertake strength training.

II. Sources of BCAAs

Since BCAAs are essential amino acids, they have to be supplied either through diet or through dietary supplements. All food sources that are rich in proteins have sufficient amounts of BCAAs. Commonly available food sources that are rich in BCAAs include dairy products, eggs, whey, chicken an...
