French Oak Wood Extract May Boost Exercise Performance
Anyone who works out regularly wants to make their workout more effective. A recent study suggests that Robuvit, a patented natural extract from French oak wood that contains roburins and other flavonoids, may help improve performance in high-intensity training.
Participants in the study included 54 people who were given 100 mg of Robuvit three times a day with a meal or no intervention at all over the course of two weeks. During the supplementation period, all of the participants underwent the same training program in order to complete a triathlon that was designed specifically for the study. The triathlon included a swim in open seawater of 0.47 miles, a 12 mile cycle, and a 3.1 mile run, starting at 2 PM in the early summer beachside in Pescara, Italy. All of the participants completed the triathlon eight times over the course of 14 days.
At the conclusion of the study, the researchers noted an improvement in the Robuvit group in every stage of the triathlon, for a total 10.56% improvement in triathlon performance. They also noted 19.98% more plasma free radicals in the placebo group. Higher levels of plasma free radicals are a sign of delayed recovery from fatigue.
Researchers from Università degli Studi di L’Aquila and Irvine-Labs, both in Italy, conducted the study. It was published in October 2015 but just released to the US audience in August of this year.
Compounds called roburins and other flavonoids unique to oak wood are the mechanism behind the health benefits of French oak wood. Previous studies have found that French oak wood extract may help with tiredness and fatigue.
