Abstract: A long-acting improver of muscular fatigue characterized by comprising 4 kinds of amino acids made up of 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), ?-lactoglobulin, and ?-lactalbumin is used as the whey protein. Novel food or drink, and pharmaceuticals which exhibit sustained recovery effects on muscular fatigue are provided.

Abstract: An amino acid composition is provided that can promote fat burning, improve endurance, and reduce fatigue during, for example, marathons, and that can lessen obesity and increase stress resistance. The amino acid composition comprises 3.0 to 10.0 mass parts of aspartic acid, 2.5 to 9.0 mass parts of threonine, 2.0 to 9.5 mass parts of serine, 12.0 to 40.0 mass parts of glutamic acid, 7.0 to 20.0 mass parts of proline, 0.5 to 4.5 mass parts of glycine, 1.0 to 4.5 mass parts of alanine, 3.0 to 12.0 mass parts of valine, 0.1 to 0.8 mass part of cystine, 1.5 to 5.0 mass parts of methionine, 2.0 to 8.0 mass parts of isoleucine, 5.0 to 15.0 mass parts of leucine, 3.0 to 10.0 mass parts of tyrosine, 3.0 to 10.0 mass parts of phenylalanine, 4.0 to 15.0 mass parts of lysine, 0.8 to 4.0 mass parts of tryptophan, 1.5 to 5.0 mass parts of histidine, and 2.0 to 6.0 mass parts of arginine, wherein the total amount of these amino acids is 100 mass parts.

Abstract: An amino acid composition or an amino acid solution for improving central functions which contains threonine, proline, glycine, valine, isoleucine, leucine, tyrosine, phenylalanine, lysine, aspartic acid, serine, glutamic acid, alanine, methionine, tryptophan, histidine and arginine; and an amino acid composition or an amino acid solution derived from the above composition by removing tryptophan. These amino acid compositions have effects of improving central functions such as healing fatigue, originate from natural materials and have substantially no side effect.

Abstract: The present invention forms a mixture basically consisting of threonine, proline, glycine, valine, isoleucine, leucine, tyrosine, phenylalanine, lysine, aspartic acid, serine, glutamic acid, alanine, methionine, histidine and arginine as a unit, by which a body temperature raising effect was observed. The similar body temperature raising effect was observed when carnitine and/or tryptophan is added to the unit. These groups were found to be amino acid mixture-containing agents capable of raising body temperature for food or drink use or medical use. The agents have excellent body temperature raising effect, thereby having the functions of reduction of accumulated body fat, alleviation of excess sensitivity to cold, warming of a cold body, and the like.

Abstract: An amino acid-trehalose composition comprising an amino acid composition which comprises proline, alanine, glycine, valine, threonine, leucine, histidine, lysine, isoleucine, arginine, phenylalanine, and tyrosine; and trehalose. The amino acid-trehalose composition has effects of compensating the reduction of the blood level of amino acids associated with severe exercise, of improving the exercise, of reducing the degree of fatigue after exercise and of recovering from fatigue. In addition, the administration of the composition permits the inhibition of the consumption of amino acids associated with exercise and any induction of fatigue accompanied by exercise.

Abstract: An amino acid composition comprising the following amino acids at the following molar ratio: proline (12.6 to 23.4), alanine (8.4 to 15.6), glycine (13.3 to 24.9), valine (8.2 to 15.4), threonine (5.0 to 9.4), eucine (4.3 to 8.1), histidine (1.8 to 11.9), serine (1.7 to 3.3), lysine (6.0 to 11.2), isoleucine (3.1 to 5.9), glutamic acid (2.2 to 10.4), arginine (2.4 to 4.6), phenylalanine (2.6 to 5.0), tyrosine (4.2 to 7.8) and trypsin (1.5 to 2.9). The composition supplements blood amino acids reduced during hard exercise and shows effects to improve motor function, to reduce fatigue after exercise and to help recovery from the fatigue.
