A new study published online in the Journal of Applied Physiology shows additional benefits of consuming a blend of soy and dairy proteins after resistance exercise for building muscle mass. Researchers from the University of Texas Medical Branch found that using a protein blend of soy, casein and whey post-workout prolongs the delivery of select amino acids to the muscle for an hour longer than using whey alone. It also shows a prolonged increase in amino acid net balance across the leg muscle during early post-exercise recovery, suggesting prolonged muscle building.
The study was conducted by researchers from UTMB in collaboration with DuPont Nutrition and Health. “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 Blake B. Rasmussen, chairman of UTMB’s Department of Nutrition and Metabolism and lead researcher of the study.
This new research, using state-of-the-art methodology, builds on an earlier publication reporting that a soy-dairy blend extends muscle protein synthesis when compared to whey alone, as only the blended protein kept synthesis rates elevated three to five hours after exercise. Together, these studies indicate that the use of soy-dairy blends can be an effective strategy for active individuals seeking products to support muscle health.
“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 for DuPont Nutrition and 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.”
The double-blind, randomized clinical trial included 16 healthy subjects, ages 19 to 30, to assess if consumption of a blend of proteins with different digestion rates would prolong amino acid availability and lead to increases in muscle protein synthesis after exercise. The protein beverages provided to study subjects consisted of a soy-dairy blend (25 percent isolated DuPont Danisco SUPRO soy protein, 50 percent caseinate, 25 percent whey protein isolate) or a single protein source (whey protein isolate). Muscle biopsies were taken at baseline and up to five hours after resistance exercise. The protein sources were ingested one hour after exercise in both groups.
The study demonstrates that consuming a soy-dairy blend leads to a steady rise in amino acids, the building blocks of muscle. The data showed that the soy-dairy blend yields an increase in select amino acid delivery for about an hour longer than the use of whey protein alone. The blend also sustained a greater positive net amino acid balance than whey, suggesting there is less muscle protein breakdown during the time period shortly after consumption of a blended protein product.

Watched my first Khan Academy video!
Genial: http://www.khanacademy.org
i m new at khan academy….
This is fantastic software. And it’s free. Instead of wasting money of
stupid iPads, schools should be integrating this into their curriculum.
http://www.khanacademy.org
Love the #KhanAcademy stuff. I wish we could use this kind of thing as a
layer close to the base of the #gamification of the collegiate curriculum
project
I think this is the first time I wished I had more free time, so that I
could do *math*.
You guys should check out Khan Academy ….its awesome!!!
Learning.Evolved.
Everyone, you must take a look at this!
I cant describe how excited I am about finding Khanacademy.org. It’s such a
beautiful idea coming together, and the possibilities are endless with this
tool around.Now go and LEARN!
Data Analytics meets achievements for real learning, count me in.
do you there would be this kind of software for chem/biology?? it would be
nice 🙂
The public schools are insistent on well roundedness at the sacrifice of
denying that the basics are down pat first. Yes “enrichment” is important
but IMO not at the sacrifice of losing the child from the basics. There are
private schools but the best ones that ensure that the basics will be down
pat, you lose the enrichment of the arts. So do you want an educated dry
kid or an “explorative” young adult that has to spend the first 2-4 years
in college to struggle in math, reading and writing?
Fantastic. All carrot, no stick.
