Soy protein plays critical role in building muscle mass


Soy and Sports Nutrition

Sports nutrition is broadly defined as the discipline of nutrition supplementation to promote human performance, recovery or body composition.  Soy is a critical ingredient in sports nutrition products because it is a complete, high-quality protein that is widely available. Optimizing the blend of proteins in post-exercise food intake is the key to achieving maximum benefits of an exercise program.  

Building muscle mass

Amino acids, the building blocks of protein, are necessary for adding muscle mass following exercise. Blood flow to muscles is elevated in the hours after exercise, accelerating the delivery of amino acids. The three-hour period following a workout is referred to as the "anabolic window" — where amino acids stimulate additional muscle synthesis. Research shows weight training and protein intake during the anabolic window improve muscle gain. More importantly, failure to feed exercised muscles during this recovery window can actually lead to muscle loss.Click here for full story. 

Soy protein benefits

Amino acids and antioxidants help promote post-exercise muscle recovery.  Glutamine and arginine are essential amino acids that help regulate muscle protein balance. They both are natural signals for growth hormone release and play an important role in building muscle. Glutamine plays a role in the immune system and is a precursor of glutathione, an antioxidant that protects cells from free radical damage. Glutamine concentrations are lower in over-trained or chronically fatigued athletes as compared to healthy, trained athletes and non-athletes. Arginine, by increasing muscle blood flow, helps bring available nutrients to muscles to speed recovery and may play a role in immune response. Soy protein has about 30 percent more glutamine and three times more arginine, as compared to whey. Click here for full story. 

Protein diversification is optimal

Isolated soy protein, whey and casein are three proteins widely used in sports nutrition. Their differing digestion rates and amino acid ratios give them unique functionality for inclusion in sports nutrition products.  Any combination of isolated soy protein, casein and whey protein will be a nutritionally “complete protein,” because each has a PDCAAS (Protein Digestibility Corrected Amino Acid Score) of 1.00. PDCAAS is the preferred measure of protein quality by the World Health Organization and the U.S. Food & Drug Administration. The optimal formulation for a blend of isolated soy protein, casein and whey protein should provide enough whey protein to jump-start muscle development and enough soy and casein to maintain nutrient delivery to muscles.

The truth about soy

Most sports nutrition products use isolated soy proteins, which are easily digestible and unlikely to cause indigestion or gas, as is sometimes thought to be the case.  Moreover, multiple research studies dismiss the myth that high intake of soy in male athletes lowers testosterone levels and increases the level of estrogen. Hormone levels and fertility rates also were unaffected. Similar studies were conducted with female gymnasts, male and female rowers and world-class swimmers. No negative effects were seen, and blood hormone levels were normal, yet subjects gained lean body mass and athletic performance.  Click here for full story.
