2. Brief Description of the Background Art
This section describes background subject matter related to the disclosed embodiments of the present invention. There is no intention, either express or implied, that the background art discussed in this section legally constitutes prior art.
Fatigue is an important factor that influences physical performance. It has two components, central fatigue and peripheral fatigue. Central fatigue has been described in the art as relating to neuronal inputs to muscle and the brain circuitry that drives them. Peripheral fatigue relates to nutritional, hormonal, and mechanical aspects of metabolism and physiology that directly affect muscle tissue. Dietary amino acids and protein have been examined for their affect on peripheral and central fatigue, particularly from the metabolic and neurochemical perspectives. Fernstrom and Wolfe, Introduction to symposium on branched-chain amino acids in exercise, J. of Nutrition 136: 524S (2006).
It is alleged in the art that (1) branched chain amino acids (BCAAs) can become depleted in muscle and plasma during exercise, producing a negative impact on muscle energy economy and promoting muscle fatigue, and (2) plasma BCAA depletion can indirectly increase tryptophan uptake into the brain, stimulate neuronal serotonin synthesis and release, causing central fatigue. Supplying BCAAs during training and competition has been described in the art as beneficial to both muscle function and mental focus by preventing BCAA depletion. Fernstrom, Branched-chain amino acids and brain function, J. of Nutrition 135: 1539S-1546S (2005) (please see page 1541S).
The BCAAs leucine, isoleucine, and valine account for 35-40% of the dietary essential amino acids in body protein and 14-18% of the total amino acids in muscle proteins. Shimomura et al., Nutraceutical effects of branched-chain amino acids on skeletal muscle, Journal of Nutrition 136: 529S-532S (2006) (please see page 529S).
BCAAs have been portrayed in the art as having anabolic effects on protein metabolism by increasing the rate of protein synthesis and decreasing the rate of protein degradation in resting human muscle. Also, during recovery from endurance exercise, BCAAs have been alleged to have anabolic effects in human muscle. Bloomstrand et al., Branched-chain amino acids activate key enzymes in protein synthesis after physical exercise, Journal of Nutrition 136: 269-273 (2006) (please see Abstract).
PCT Patent Publication Number WO 2004/049830, published Jun. 17, 2004 by applicant Tsuchita et al., describes an improver of muscular fatigue comprising 4 kinds of amino acids (leucine, isoleucine, valine and glutamine), and a whey protein component (whey protein and/or decomposition product of whey protein). At least one of a whey protein isolate (WPI), a whey protein concentrate (WPC), β-lactoglobulin, and α-lactalbumin is used as the whey protein.” (Please see the Abstract).
Citrulline malate is another anti-fatigue substance that has been described in the art. It has been suggested to have a protective effect against acidosis and ammonia poisoning, which may explain its anti-fatigue properties. Activity of citrullline malate on acid-base balance and blood ammonia and amino acid levels, Arzneimittelforschung 41: 660-663 (1991) (please see Abstract).
Citrulline malate is usually prescribed as an antiasthenic treatment. It is also known in the art by the trade name Stimol™ or the CAS registry number 5490-97-5, and it is a mixture of citrulline, which is involved in the urea cycle, and malate, a tricarboxylic acid cycle (TCA) intermediate. Bendahan et al., Citrulline/malate promotes aerobic energy production in human exercising muscle, British Journal of Sports Medicine 36: 282-289 (2002) (please see Introduction).
In a study by Bendahan et al., ingestion of 6 grams per day of citrulline malate for 15 days was alleged to result in a significant reduction in the sensation of fatigue. Citrulline/malate promotes aerobic energy production in human exercising muscle, British Journal of Sports Medicine 36: 282-289 (2002) (please see Abstract).
Japanese Patent Application Number JP1988000281672, published May 17, 1990 by Hiroko et al., describes an amino acid-containing food composition without the bitter taste stemmed from the amino acids. The composition described contains (A) amino acids(s) (pref. isoleucine, leucine, lysine, methionine, phenylalanine, tryptophan, valine, arginine, histidine, citrulline, omithine or proline) and/or peptide, and (B) tea and/or the flavoring component(s) thereof. The disclosure teaches that it is preferable that the amino acid concentration be 0.1 to 60 wt. % and the concentration of the tea and/or the flavoring component(s) thereof be 0.1 to 50wt. % in the final product.

As a preface to the detailed description presented below, it should be noted that, as used in this specification and the appended claims, the singular forms “a”, “an”, and “the” include plural referents, unless the context clearly dictates otherwise.
In instances where the word “about” is used in this document, this indicates that the precision of a value is within about ±10%.
Disclosed herein is a powdered compound which can be mixed into various liquids and soft foods to provide improved muscle growth while simultaneously reducing fatigue. The powdered compound comprises a relatively high concentration of edible nutritional protein, citrulline malate, and branched chain amino acids (BCAAs). Despite the bitter and unpalatable taste of the citrulline malate and BCAAs individually, the powdered compound of the invention imparts an overall pleasing taste.
The nutritional protein is an edible nutritional whey protein. The concentration of whey protein present in the composition ranges from about 10% by weight to about 96% by weight, and may be about 20% by weight to about 90% by weight. The whey protein may be present as two ingredients, where a first ingredient is a whey protein isolate in which the whey protein concentration is at least 90% by weight. The second ingredient may be a whey protein concentrate in which the whey protein concentration ranges from about 25% by weight to about 89% by weight, and may be about 80% by weight.
The BCAAs include L-isoleucine, L-leucine, and L-valine. However, these BCAAs may be present individually or in various combinations. Each may be present at a concentration of about 0.01% by weight to 5.0% by weight. In one embodiment they are each present at a concentration of about 0.01% by weight to 0.50% by weight. In another embodiment they are each present at concentration of about 1.0% by weight to 2.0% by weight.
The citrulline malate ranges from about 1% by weight to about 15% by weight. In one embodiment the citrulline malate is present at about 10% by weight.
Polypeptides and amino acids of the kind which are related to muscle and nerve tissue development may be added optionally, for particular end use applications. Examples of polypeptides which may be added to the composition include glutamine peptides and hydrolyzed whey protein peptides having a molecular weight of less than about 10,000 Daltons (typically having a molecular weight ranging from about 1,000 to about 10,000 Daltons). Amino acids and their analogs and derivatives which may be added to the composition include phosphatidylcholine, Taurine, L-Glutamine, L-Arginine, L-Phenylalanine, L-Tyrosine, L-Citrulline, and N-acetylcysteine, by way of example and not by way of limitation. The concentration of amino acids and their analogs and derivatives in the composition ranges from about 0.01% by weight to about 15.0% by weight, more typically the concentration is in the range of about 0.11% by weight to about 11% by weight.
Antioxidants which provide antioxidant potentiating properties in the body may also be included in the composition. Examples of such antioxidants include lecithin, lactoperoxidase, and lactoferrin, not by way of limitation. Typically the concentration of antioxidants ranges from about 0.01% by weight to about 5.0% by weight in the composition, more typically the concentration is in the range of about 0.1 1% by weight to about 0.15% by weight.
A hyper-immune milk protein concentrate may be added to help protect joints. The concentration of this hyper-immune milk protein concentrate ranges about 1% by weight to about 20% by weight. In one embodiment the hyper-immune milk protein is present at about 7% by weight.
A preservative of the kind known in the food industry may be added to provide freshness. A preferred preservative is tocopherol (vitamin E). The concentration of preservative ranges from about 0.01% by weight to about 1.0% by weight. In one embodiment the concentration of preservative is in the range of about 0.01% by weight to about 0.015% by weight.
Various flavorings and sweeteners (preferably artificial sweeteners to reduce the amount of carbohydrates in the compound) may be added to provide palatability. For example, vanilla flavorings may be present at a concentration ranging from about 1% by weight to about 5% by weight. Artificial sweeteners may be present at a concentration ranging from about 0.1% by weight to about 1.0% by weight. In one embodiment artificial sweetener is present at about 0.11% by weight.
One skilled in the art of food and dietary supplements will recognize that there are a number of different flavorings and antioxidants which may be used in combination with the edible nutritional whey protein, branched chain amino acids, and citrulline malate. In addition, there are a variety of polypeptides and amino acids which are known to be beneficial to the body and which may be added to the composition as well, for particular remedial health benefits. It is not intended that the scope of the invention be limited to the exemplary compositions described herein.
