Polyphenol Supplement May Boost Workout Performance
Workout capacity relies more on anaerobic metabolism, which can have a limiting impact on muscle function and performance. A recent study suggests that taking a supplement containing polyphenols from grape, pomegranate, and green tea extract may improve power and performance during high-intensity exercise.
Participants in the study included 15 recreationally-active people who were given either 900 mg of the polyphenol supplement or a placebo before participating in high-intensity anaerobic exercise.
At the conclusion of the study, the researchers noted a 5% increase in total anaerobic work capacity in the supplement group. They also noted a 3.7% increase in maximal peak power output and a 5% increase in the average power developed. The supplement group also had significantly lower blood pressure after exercise, when compared with the placebo, as well as improvements in antioxidant enzyme SOD activity.
Researchers from UCAM Universidad Católica de Murcia in Spain and Université de Montpellier in France conducted the study. It was published on April 24, 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.
