Studies related to Power Output and Theaflavins

The Effects Of Theaflavin-enriched Black Tea Extract On Muscle Soreness, Oxidative Stress, Inflammation, And Endocrine Responses To Acute Anaerobic Interval Training: A Randomized, Double-blind, Crossover Study

As assessed by a Wingate cycling test, 1760mg of Black Tea (40% Theaflavins) over 9 days prior to testing was associated with increased peak power output and reduced cortisol and soreness.
