Rice protein supplement and methods of use thereof

Abstract

Some embodiments relate to nutritional supplements comprising rice protein isolate. Some embodiments of the nutritional supplement comprise less than about 90 mg of leucine per gram of rice protein isolate and less than about 50 mg of lysine per gram of rice protein isolate. Some embodiments pertain to methods of using the nutritional supplements described herein to achieve one or more of weight gain, weight maintenance, growth, muscle growth, muscle maintenance, decreased muscle loss, or improved exercise training results.

What is claimed is: 
     
         1 . A nutritional supplement, comprising:
 a protein comprising:
 about 80 mg of leucine per gram of protein; and 
 about 31 mg of lysine per gram of protein; 
   wherein the protein of the nutritional supplement consists only of protein from rice.   
     
     
         2 . The nutritional supplement of  claim 1 , wherein the nutritional supplement further comprises about 41 mg of isoleucine per gram of protein. 
     
     
         3 . The nutritional supplement of  claim 1 , wherein the nutritional supplement further comprises about 58 mg of valine per gram of protein. 
     
     
         4 . The nutritional supplement of  claim 1 , wherein the protein comprises about 54 mg alanine, about 77 mg arginine, about 87 mg aspartic acid, about 21 mg cysteine, about 174 mg glutamic acid, about 43 mg glycine, about 22 mg histidine, about 41 mg isoleucine, about 80 mg leucine, about 31 mg lysine, about 28 mg methionine, about 53 mg phenylalanine, about 45 mg proline, about 49 mg serine, about 35 mg threonine, about 14 mg tryptophan, about 47 mg tyrosine, and about 58 mg valine per gram of protein. 
     
     
         5 . The nutritional supplement of  claim 1 , wherein the protein is a brown rice protein. 
     
     
         6 . A method of improving a result of exercise training, comprising:
 administering the nutritional supplement of  claim 1  to a subject, wherein ingestion of an effective amount of the nutritional supplement by the subject results in at least one of decreased fat-mass, increased lean body mass, and increased skeletal muscle hypertrophy.   
     
     
         7 . The method of  claim 6 , wherein the administering comprises administering a 48 gram dose of the nutritional supplement to the subject following each session of an 8-week periodized training protocol. 
     
     
         8 . The method of  claim 6 , wherein the rice protein is a brown rice protein. 
     
     
         9 . A method of improving a result of exercise training, comprising:
 administering the nutritional supplement of  claim 1  to a subject, wherein ingestion of an effective amount of the nutritional supplement by the subject results in at least one of increased power and increased strength.   
     
     
         10 . The method of  claim 9 , wherein the administering comprises administering a 48 gram dose of the nutritional supplement to the subject following each session of an 8-week periodized training protocol. 
     
     
         11 . The method of  claim 9 , wherein the rice protein is a brown rice protein. 
     
     
         12 . A method for improving a result of exercise training in a subject, the method comprising:
 administering to the subject a nutritional supplement comprising a protein, the protein of the nutritional supplement consisting of rice protein;   the rice protein comprising:
 about 80 mg of leucine per gram of protein in the rice protein isolate; 
 about 31 mg of lysine per gram of protein in the rice protein isolate; 
 about 41 mg of isoleucine per gram of protein in the rice protein isolate; and 
 about 58 mg of valine per gram of protein in the rice protein isolate; and 
   wherein ingestion of an effective amount of the nutritional supplement by the subject results in at least one of increased power and increased strength.   
     
     
         13 . The method of  claim 12 , wherein the administering comprises administering a 48 gram dose of the nutritional supplement to the subject following each session of an 8-week periodized training protocol. 
     
     
         14 . A method of supplementing the diet of a subject, comprising:
 administering a nutritional supplement comprising protein to a subject;   wherein the protein of the nutritional supplement consists only of rice protein; and   wherein ingestion of an effective amount of the nutritional supplement by the subject results in at least one of decreased fat-mass, increased lean body mass, increased skeletal muscle hypertrophy, increased power, and increased strength.
