Protein is an important component to any athlete's workout routine. Protein, according to research, provides the body with the amino acids necessary to build muscle tissue. Whey protein is considered to be the highest quality form of protein, making it the best protein choice for any athlete.

Amino acids are important for everyone, but they are particularly important to athletes. This is because branched chain amino acids are used up by muscles during exercise, rather than being metabolized by the liver. This can cause feelings of fatigue. Therefore, people who exercise regularly need an increased amount of amino acids to maintain energy levels. These necessary amino acids are provided by whey protein.

Since whey protein is soluble, it is an easy to digest protein. This helps it be absorbed more efficiently into the body. For this reason, it is able to quickly provide necessary nourishment to the muscles. Since athletes break down their muscles when they exercise, this is especially important. Whey protein helps repair these broken down muscles, and then it helps rebuild them. In this way, whey protein not only helps muscles recover from exercise, by it helps them grow faster, as well.

Whey protein also makes carbohydrates more effective in muscle building. In fact, research has shown that the uptake of the amino acid L-phenylalanine is increased by three times or higher when a post-workout shake includes both carbohydrates and whey protein.
