Proteins play a number of very important roles in the body, these include the repair of body cells, reparation and building of collagen tissue (muscle, bone, etc.), energy provision and regulation of many important metabolic processes.
The human body contains approximately 65% water and 25% protein.
Protein is a nutrient made up of chains of usually hundreds of amino acids. The enzyme Pepsin digests the proteins in the stomach. This enzyme splits the proteins into smaller particles, namely polypeptides. These polypeptides are split into even smaller particles, the free amino acids. The amino acids are then taken up by the intestinal wall and delivered into the bloodstream. Through the bloodstream all amino acids are transported to the liver and if necessary transformed. After this each amino acid gets its own destination.
There are twenty-four different amino acids, eight of these are essential amino acids, from these eight the remaining non-essential amino acids can be made. All essential amino acids must be obtained through the daily diet. The body can’t function without these essential amino acids. The balance of the amino acids in the protein of any food determines its quality or usability.
Well-controlled research studies have been done to determine the exact amount of protein needed in athletes and weightlifters to lead to what is called nitrogen balance. Nitrogen balance occurs when the amount of protein that goes into the body (food, supplements) is equal to the protein that leaves the body (sweat, urine, faeces etc.). The results of these studies have demonstrated that endurance and strength athletes often require more than double the amount of protein of the average sedentary person. These research reports are available at our head quarters.
This means that endurance athletes need about 1.2-1.4 g/kg protein a day and strength athletes 1.7-2.0 g/kg a day to achieve nitrogen balance rather than the Recommended Daily Allowance (RDA) of only 0.8 g/kg. . Recommended Daily allowances (RDA’s) were instituted over forty years ago, unfortunately the amounts recommended only give us the bare minimum requirements to prevent deficiency. Preventing a deficiency will not lead to the best performance possible, what we really want is optimal performance and/or muscle mass.
Whey protein is a high quality and nutritious dairy protein. Milk contains two primary proteins: casein and whey. In the production of cheese the liquid whey separates from the casein. The whey proteins are then separated from the liquid whey and purified to obtain a highly concentrated protein.
Whey protein is the highest quality complete protein available, it contains all of the essential amino acids required by the body each and every day. Our Whey protein hydrolysate has the highest biological value of 156. The biological value is a measure of protein quality. It indicates the amount of protein that is retained from the absorbed protein for maintenance and growth.
The reference for biological value is egg protein which has a score of 100.
Unlike meat, vegetable and egg protein, whey protein also contains the same major component found in mother’s milk, alpha-lactabumine.
Protein-depleted individuals have impaired immuno-competence. Part of this impairment can be ascribed to limited availability of amino acids for synthesis of cellular proteins of the immune system and to support the hepatic acute phase protein response. Amino acids are also involved in other aspects of the defence mechanism
Whey proteins help to maintain adequate levels of glutathione (GSH). GSH is a water-soluble anti-oxidant (synthesised from glutamate (glutamine), glycine, and cysteine) that is needed for a healthy immune system. Intensive exercise, stress and pollution deplete GSH levels leaving the body venerable to disease. Numerous studies are now exploring other areas where the use of whey protein may be beneficial. Additional studies are needed but promising areas include: cancer treatment, HIV, stress reduction, hypertension and appetite suppression
Whey Protein Isolate induces a dramatic increase of plasma amino acids this is perfect for the build up of muscle tissue (anabolism) but this increase is short-lived. To prevent muscle protein breakdown (catabolism) we need slow release proteins . That’s why we added Magnesium Caseinate and egg white protein to W Force.
Caseinate creates a prolonged release of amino acids to the body. Caseinates clot in the stomach which delays its gastric emptying. Nowadays much of our daily foods is enhanced with calcium. For the right calcium-magnesium balance it is necessary to obtain enough magnesium through our daily diet. That’s why W Force is the first and only combined protein supplement that uses Magnesium Caseinate. Magnesium also offers several more advantages for the athlete for example it has a crucial role in the production of ATP, muscle contraction and relaxation.
Egg white has the advantages of a high biological value and a slow release of amino acids. The balance of the amino acids is very similar to that found in the human body. That is why this protein combined with the two milk proteins offers a superior balance in all amino acids.
Glutamine is the most abundant amino acid in the body, particularly in the muscles. Glutamine is critical to the athlete because it precedes the synthesis of other amino acids and nucleotides. Next to being one of the most powerful anabolic and anti catabolic nutrients available it also helps to boost the immune system. It appears to play a specific role in maintaining function of rapidly proliferating cells such as lymphocytes and mucosal enterocytes. It is noteworthy that under conditions of infection and trauma muscle concentrations of glutamine fall.
Intensive training over extended periods will deplete muscle and blood glutamine levels. If glutamine stores are not replenished, glutamine is pulled from the muscles themselves. The body will end up in a catabolic stage with depressed protein synthesis and will start to loose muscle mass.
Branch-chained amino acids (BCAA) are 3 essential amino acids namely Isoleucine, Leucine and Valine. BCAA have been proven in studies to help increase strength, boost performance and promote lean body mass while selectively reduce body fat. BCAA can exert anabolic effects by facilitating the release of anabolic hormones such as insulin, growth hormone and insulin-like growth factors (IGF). BCAA also prevent protein breakdown. Studies have shown that BCAA can exert anti-catabolic effects and preserve lean body mass. Unlike other amino acids BCAA can also be oxidised as fuel during prolonged exercise. During such exercise they help to maintain blood sugar levels through the alanine-glucose cycle.
Carbohydrates are the main suppliers of body energy. They also add volume to a meal filling the stomach and giving you a sated feeling. Subsequently during the digestive processes the most important kinds of carbohydrates – better known as starch and sugar – are broken down to form glucose or blood sugar. From blood sugar the important energy required by the nerves and brain is produced. To prevent (muscle tissue building) proteins in your food from being used as energy supply, you add carbohydrates to your diet. Carbohydrates are just as important for your health as fats and proteins. It is recommended to make sure that reasonable percentage of your daily food-intake consists of carbohydrates. Preferably complex carbohydrates. Complex carbohydrates are found in: * pasta * vegetables, dried subtropical fruit * legumes (brown and white beans, marrow-fat peas and common peas) * rye bread, whole meal and brown bread * whole meal products such as oatmeal, muesli, wild rice, maize, whole-wheat macaroni * nuts, peanuts and linseed. Simple carbohydrates are found in: * sugar, sweets * confectionery * biscuits, crackers and toast
It is important to know more about fats. Contrary to what most people think, fats are a very important part of food and are essential for numerous body processes. The most important function of fat is the production of energy and as carrier. Vitamins A, D, E and K can only be dissolved in fat. Fat may be of animal or vegetable origin. It is important to make distinction between ‘good’ and ‘bad’ fats. Saturated fats are the “bad” kind. Your body uses them for the production of energy. If you eat too much of these every day, it causes the increase of cholesterol levels, vascular constriction and of course an increase fat . Unsaturated fats are chemically processed or of plant origin. Examples are: sunflower oil, olive oil and (ground)nuts. Fatty acids (among those the so called tri-glycerids) are used by the body to form cell-membranes, to support the central nervous system, to produce a number of important hormones and for many other essential body processes like the production of energy. Fatty acids are often used for long distance performance. Fish is a great source of Omega 3 & 6 oils. Fish oil has proved to be a healthy source for energy and anti-oxidation, recuperation and health protection. Other good sources of fats are nuts (especially wall nuts, chess nuts) etc. Unsalted nuts are better than salted ones. For the benefit of your digestive system it is good to add some olive oil to the daily food (such as salads). Tuna is a good lunch part of a sandwich (take the water filed). When young (<30 years of age) fats in butter are all right to use sometimes, over 35 years of age margarine is preferred. When taking dairy products of any kind be aware of the fat levels. Dairy products are often a source of great inconvenience for many people due to lactose intolerance, therefore it is strongly advised NOT to take your daily supplements with milk but with fruit juice. If you do have a body that easily creates fat please do avoid the eating of larger amounts of primary sugars, these turn into fat quite easily.
