Three capsules of Grape Seed Extract protect muscles during extreme strength training
Study
The researchers used capsules with MegaNatural-BP from the American company Polyphenolics. [polyphenolics.com] That application, which you can find in quite a few supplements, is standardized on procyanidins.
On the first day of the experiment, the students, who were not used to strength training, trained their biceps on a preacher curl machine. The subjects did 2 eccentric sets of 25 reps each. That's a recipe for major muscle damage.
24, 48, 72 and 96 hours after biceps training, the researchers determined how much muscle pain the subjects had on the basis of a questionnaire. They also determined the maximum strength that the students could develop with a bicep curl, and how much creatine kinase was in their blood.
The concentration of creatine kinase in blood is a marker for muscle damage. The higher the concentration, the greater the muscle damage.
Results
The effect of supplementation on the concentration of creatine kinase after the workout was statistically significant. Grape Seed Extract reduced the increase in the blood levels of the test subjects.
Mechanism
"The anti-oxidation and anti-inflammatory effect of Grape Seed Extract are well known, and experimental studies have reported significantly decreased levels of oxidative stress and inflammatory factors with Grape Seed Extract."
"Thus, there is a possibility that supplementation with phenol content-rich Grape Seed Extract would decrease creatine kinase levels by decreasing oxidative stress or the inflammatory response."
