New Study Finds a Protein Combination (Soy, Whey, Casein) is Best to Consume Post-Workout for Building Muscle

24.04.2012
Today at Experimental Biology 2012, Dr. Blake Rasmussen and colleagues presented a new and first-of-its-kind clinical study: “Effect of Protein Blend vs. Whey Protein Ingestion on Muscle Protein Synthesis Following Resistance Exercise.”

The results of this study suggest that a protein blend (combination of soy, whey and casein) may be best to consume post-workout for building muscle. Specifically, the blend of proteins in this study showed an increase in a person’s “anabolic window” (the amount of time it takes for building muscle to occur post exercise).

“This study confirms that consuming a blend of proteins (soy, whey and casein) versus whey protein alone provides a prolonged delivery of amino acids to the muscles, making it optimal for consumption following resistance exercise,” said Dr. Rasmussen, professor and interim chair of the Department of Nutrition & Metabolism at the University of Texas Medical Branch and the senior author of this study. “The results of this study are critical for sports nutrition consumers and regularly active individuals.”

The protein in the blend used in this study consisted of 25 percent isolated soy protein, 25 percent isolated whey protein and 50 percent casein. This combination of protein blends was determined in a preclinical study, of which was presented at Experimental Biology 2011.

Soy, whey and casein proteins are all absorbed at different rates during digestion. Whey protein is referred to as a "fast" protein because it is rapidly absorbed whereas casein, a "slow" protein, requires several hours to be digested. The ability of soy protein to deliver amino acids is “intermediate,” meaning concentrations in blood peak somewhat later compared to whey, but its digestion rate is much quicker than casein. Hence, the effect of all three of these proteins combined appears to provide the extended release of amino acid delivery to the muscles.

“Your muscles don’t recover in 30 minutes. It takes at least 24-48 hours for your muscles to recover after a resistance exercise,” said Greg Paul, global marketing director for sports nutrition and weight management, Solae. “This study showed that protein blends can provide amino acid delivery for up to five hours, meaning if you consume a product or protein shake with these blends, the prolonged effect will deliver essential amino acids to feed your muscles until your next meal.”

This was a double-blind, randomized clinical trial in nineteen young adults before and after ingestion of ~19 grams of protein from the blend or ~17.5 grams of whey protein (10 and 9, respectively, per group).

Additional detailed results from this study will be revealed at the upcoming American College of Sports Medicine annual meeting May 29-June 2 in San Francisco, Calif. This study used Solae™ SUPRO® isolated soy protein. For more information on this study, contact Dr. Rasmussen at blrasmus@utmb.edu.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
