"This study sheds new light on how unique combinations of proteins, as opposed to single protein sources, are important for muscle recovery following exercise and help extend amino acid availability, further promoting muscle growth," said lead researcher Blake B. Rasmussen, Ph.D., Chair, Dept. of Nutrition & Metabolism at the University of Texas Medical Branch.
The double-blind, randomized clinical trial included 16 healthy subjects ages 19–30 who consumed either a soy-dairy blend or a single protein beverage consisting of whey one hour after completing resistance exercise. This study, which was conducted by researchers from the University of Texas Medical Branch in collaboration with DuPont Nutrition & Health, affirms previously published research that found that blended protein sources can extend muscle protein synthesis when compared to whey alone.
"Because of the increased demand for high-quality protein, this study provides critical insight for the food industry as a whole, and the sports nutrition market in particular," said Greg Paul, Global Marketing Director, DuPont Nutrition & Health. "With more and more consumers recognizing the importance of protein for their overall health and well-being, the results of this study have particular relevance to a large segment of the population, from the serious sports and fitness enthusiast to the mainstream consumer."
