Protein is the essential building block for muscle, bones, vital organs, and all other tissue in the human body. Protein also has important functional roles in hormone and enzyme control.

While protein itself can be broken down to fuel energy, this process keeps protein from performing more important functions in the body. Protein does however contribute to sustained energy by slowing the absorption of sugars into the bloodstream.

 Protein Type:
 What is it?
 Important Properties 
Whey Protein Isolate
(WPI)
Whey, a by-product of cheese manufacture, is processed to eliminate as much fat and lactose as possible, leaving a very high protein content (90% - 96%) compared to other protein sources.
  • Very fast rate of absorption (ideal for immediate post-exercise window)
  • Very high BCAA content for muscle building
  • Very high impact on satiety (appetite satisfaction)
  • Ultra lean (low in carbs, fat) for weight management & getting lean

Whey Protein Concentrate
(WPC)

As a result of ultra-filtration manufacturing process, WPC is an excellent source of protein, typically with a content greater than 80%. WPC may contain small amounts of fat, although much of the lactose and minerals have been removed.

  • Fast rate of absorption 
  • High BCAA content for muscle building 
  • High impact on satiety (appetite satisfaction)
Hydrolysed Whey Speeds the digestion and absorption rate
by partially breaking down the complex protein into smaller chains of amino acids called peptides.
  • Most rapid rate of absorption 
  • Very high BCAA content for muscle building 
  • Very high impact on satiety (appetite satisfaction) 
  • Ultra lean (low in carbs, fat) for weight management & getting lean
Caseinates (Calcium Caseinate,
Micellar Casein)
Aside from Whey, Casein is the other major protein fraction in cow’s milk.
  • Slow absorbing (micellar casein is the slowest) 
  • High impact on satiety by means of slow digestion rate 
  • An excellent source of Glutamine for muscle preservation and growth hormone
Egg Protein Historically referred to as the ideal protein, egg protein is processed from the egg albumen (egg white) which is rich in quality protein.
  • Slow absorbing 
  • Rich in Arginine, an amino acid believed to aid the release of Human Growth Hormone and Nitric Oxide (NO2) and consequently muscle development
Soy Protein Isolate A high-quality vegetable source of protein. Low in fat and cholesterol free.
  • Moderate rate of absorption 
  • Ideal as a complete protein source for vegetarian athletes and those with dairy allergies

Protein Diet

Foods rich in protein include eggs, meat (chicken, beef, fish), dairy, soy and legumes. Whey protein and casein-based protein powders are derived from dairy, isolating the protein-rich whey fractions and removing most of the lactose, fat and other unwanted content.

Protein & Amino Acids

Proteins consist of approximately 22 smaller units called amino acids. Eight of these are essential amino acids, meaning that, although necessary for survival and optimum functioning, they cannot be made in the body and can only be obtained in the diet.

The essential amino acids are: Valine, Leucine, Isoleucine, Phenylalanine, Tryptophan, Threonine, Methionine and Lysine.

Some of the other amino acids are classified as conditionally essential, meaning that under normal circumstances the body is not reliant upon the diet for their provision, but when certain conditions such as exercise, stress and vegetarian dieting prevail, additional intake through the diet is necessary. These amino acids are Glutamine, Arginine, Histidine and Glycine.

Three of the essential amino acids have significance for the athlete. Valine, Leucine and Isoleucine are known as branched-chain amino acids (BCAAs) and have the most integral roles in muscle development and maintenance. Whey protein is naturally high in all three BCAAs, making it the ideal protein source for athletes.

Protein synthesis, the building of new tissue and muscle growth, depends upon all of the amino acids being present in optimal proportion. The amino acid profile varies per protein food source; not all contain the amino acids required in the optimal balance.

Protein Rate of Absorption

Proteins also differ in their rate of absorption in the body. This has important applications for the athlete in recovery.

A fast absorbing protein is critical immediately after exercise for maximising protein-to-muscle synthesis. Slower absorbing proteins work anti-catabolically, minimising muscle protein losses over a long period.

Longer digestion time also assists appetite control, which is important for the leaning phase and weight management.

Protein Nutritional Requirements

Athletes have greater nutritional requirements for both carbohydrates and protein.

It’s not unreasonable for athletes to obtain as much as 65-70% of their total daily energy intake from carbohydrate food sources, as this is the body’s preferred fuel source. Additionally the need for increased muscle size and strength requires additional protein in the diet.

Protein requirements can vary among different athlete types as shown here:

Activity   Protein requirements g/kg bodyweight/day  
Body builder  2.0
Elite endurance  1.6
Recreation endurance  1.0
Power sports  1.4-1.7
Early resistance training 1.5-1.7
Steady resistance training 1.0-1.2
Sedentary individual 0.8
