Supplementation with a Polyphenol-Rich Extract, PerfLoad^®, Improves Physical Performance during High-Intensity...

Area of Science:

• Exercise Physiology
• Nutritional Biochemistry

Background:

• Peak exercise performance relies on anaerobic metabolism, which can negatively impact muscle function.
• High-intensity exercise under anaerobic conditions induces metabolic imbalance and oxidative stress.

Purpose of the Study:

• To evaluate the efficacy of a polyphenol-based supplement, PerfLoad®, in improving metabolic homeostasis and physical performance during anaerobic exercise.
• To assess the impact of PerfLoad® on exercise-induced oxidative stress.

Main Methods:

• A randomized, double-blind, crossover study involving fifteen recreationally-active male athletes.
• The Wingate test on a cycle ergometer was used to assess maximum anaerobic power.
• Measurements included total power output, peak power output, average power, fatigue levels, and heart rate.

Main Results:

• Supplementation with PerfLoad® significantly increased total power output (5%), maximal peak power output (3.7%), and average power developed (5%).
• No significant increase in fatigue or heart rate was observed in supplemented subjects.
• Oxidative homeostasis was stabilized in athletes supplemented with PerfLoad®.

Conclusions:

• PerfLoad® is a natural and effective supplement for improving athletic physical performance during high-intensity anaerobic exercise.
• The supplement helps balance metabolism and reduce exercise-induced oxidative stress, similar to training adaptations.
• PerfLoad® offers a viable solution for athletes seeking to enhance performance while managing metabolic stress.
