Polyphenol Formulation May Improve Performance During High-Intensity Exercise


Fytexia’s PerfLoad is a flavonoid-rich ingredient formulated from grape, pomegranate, and green tea extracts.

France-based Fytexia, which recently launched a new range of sports nutrition ingredients supported by clinical research, said a new clinical study published in the journal Nutrients demonstrates the benefits of PerfLoad, a flavonoid-rich ingredient formulated from grape, pomegranate, and green tea extracts.
The natural composition has been designed to target heavier performance using polyphenol strength to improve peak power and total anaerobic work capacity.
A randomized, placebo-controlled, crossover study, was conducted in the Research Center of High Performance Sport of the University of Murcia (Spain) to evaluate whether PerfLoad could improve physical performance during high-intensity exercise, in anaerobic condition, while sustaining physiological and biochemical processes of 15 recreationally-active sportsmen.
The Wingate test was used to assess maximum anaerobic power during a high intensity exercise on a cycle ergometer.
Supplementation with PerfLoad was correlated with a significant increase in the total anaerobic work capacity by 5%, which represents an increase of 876 joules developed in 30 seconds. 900 mg of PerfLoad, taken pre-workout, was shown to provide explosive power from the very start of the exercise and the maximal peak power output was significantly increased by 3.7% without inducing higher fatigue or higher heart rate at V02max. Blood markers showed that oxidative homeostasis was stabilized in supplemented subjects.
As pre-workout supplementation has become a significant nutritional approach in recent years, such results demonstrated that the water-soluble ingredient PerfLoad can be a natural and efficient solution helping athletes to improve their physical performance while balancing their metabolism and reducing exercise-induced oxidative stress, the company said.
