Solae™ soy protein with
minimum guaranteed level of isoflavones reduces exercise
oxidative stress.
Although exercise is generally considered health promoting,
it does create oxidant stress, which can contribute
to muscle soreness, inflammation and eventually fatigue.
For active people, it not only means time away from
the gym but it has been implicated in many diseases
including cancer. Soy protein can consistently produce
antioxidant effects in humans, therefore consumption
of soy protein with its naturally occurring isoflavones
may help in reducing muscle inflammation.
Solae™ soy protein with
minimum guaranteed level of isoflavones Produces Antioxidant
Effects in Athletes and Weekend Warriors; Whey Protein
did not.
Robert DiSilvestro, Ph.D., professor of Human Nutrition
at Ohio State University, recently completed a study
with 20 athletic college men undergoing an exercise
training program who were fed either 40 grams of Solae™
soy protein with its naturally occurring isoflavones
or 40 grams of whey protein as a beverage.
The group consuming Solae™ protein
showed a significant increase in plasma total antioxidants
status (TAS) while the group fed whey did not experience
any increase.
This increase in plasma TAS was associated
with the reduction of muscle enzymes in the blood including
creatine kinase and myloperoxidase. Creatine kinase
is a marker for muscle damage and myloperoxidase is
a marker for inflammation.
"Adding the benefits from the clinically researched
soy protein into your diet is a great option, particularly
for recreational athletes who tend to push themselves
at irregular times" says DiSilvestro.
