Polyphenols May Help Athletes Work Out Longer
A recent study suggests that taking a combination of grape and apple polyphenols may increase the time to exhaustion for athletes by almost 10%. This means they are able to work out longer and therefore get increased benefits from an exercise session.
Participants in the study included 48 physically active men with an average age of 31. In two separate testing sessions, the men were given either 500 mg of the polyphenol blend the evening before and one hour before testing or a placebo. Participants completed an endurance test at a high percentage of their maximal aerobic power, and time to exhaustion was measured.
The researchers found that that the supplement increased time to exhaustion of 9.7%, when compared with the placebo. They also found that the time to reach maximal perceived exertion was delayed by 12.8%.
Researchers from Université de Bourgogne-Franche-Comté in France led the study. It was published on August 22, 2017, in Nutrients.
Polyphenol intake has been linked with a variety of health benefits, including helping with weight management and reducing inflammation. Polyphenols can be found naturally in many foods, including honey, a variety of fruits and vegetables, red wine, chocolate, tea, certain oils and many types of grain.
