IMMAF world championships return zero drug positives


The International Mixed Martial Arts Federation is proud to announce that anti-doping testing at its 2021 World Championships in January returned zero positives.

In- and out-of-competition testing saw 34 samples collected from 22 males and 12 females across nine countries and resulted in 34 negative sets of test results.

IMMAF has been WADA Code-compliant since 2015, earning signatory status to the World Anti-Doping Agency at the end of last year, making it the sole amateur MMA authority to be recognized by the organization.

The World Championships saw many athletes return to competition after a prolonged hiatus and disruptions to training due to the pandemic and showcase outstanding grit and sportsmanship in their performances.

“It is fantastic to see this level of compliance," IMMAF President Kerrith Brown said. "It serves as a testament to the commitment of our Anti-Doping consultant Michele Verroken, the IMMAF team and our National Federations in implementing comprehensive, anti-doping education, and the dedication of our athletes to a clean, drug-free, honorable sport. We are proud of our recognition status under WADA and remain dedicated to the highest levels of good governance in compliance with the values of the Olympic movement – respect, friendship and real excellence."
