How Much Protein Do Athletes Need?

WHAT IS PROTEIN?

Protein is made up of essential and non - essential amino acids. A chain of amino acids is called a polypeptide. The human body can make the non - essential amino acids, whereas the essential amino acids must be ingested through food. Protein is found in food, and is most highly concentrated in animal sources than other sources. It is digested by the human body, and broken down into its amino acid components, beginning in the stomach. An enzyme disassembles the protein polypeptide chains into smaller components, which are broken down again and again in order to facilitate the digestion process. Once the protein has been broken down sufficiently, it can be absorbed and stored for

The fact is that gargantuan amounts of protein intake is not going make a world class athlete; training builds endurance and muscle, not protein alone. The average sedentary adult needs to consume only 30 to 60 grams of dietary protein per day to replace amino acids used by the body (4.) It is true that as an athlete exercises, more amino acids and protein are used by the body than a sedentary person, thus the need for dietary protein may increase. However, one must keep in mind that protein contains calories, and any excess calories that are not burned are stored as fat, and protein is an inefficient source of energy for the body to use.

PROTEIN AND ATHLETES

What evidence is there to support or disprove claims that high intake levels of protein help build muscle mass and better athletes? Muscles are made mostly of protein, so logically one would think that the more protein in the diet, the more muscle one should have. Certain types of exercise, weight lifting for example, do stimulate muscle growth. So, a combination of weight training and large amounts (the more, the better) should be beneficial, right? Not exactly. The most recent indications are that dietary protein in excess of the current recommended dietary allowance (0.8 grams of protein per kilogram of body weight per day) is likely needed for optimal muscle growth (5.) "The current recommended dietary allowance doesn't seem to be
