Ronda Rousey leads UFC roster as most-tested fighter to date by USADA

The United States Anti-Doping Agency, or USADA, has completed what they're calling the first round of testing of UFC fighters and posted the results on a new athlete test history website. The agency made the news official Thursday on their website.

According to USADA, the first round of testing, which took three months, has "primarily focused on ensuring UFC athletes have received the necessary education to understand their rights and responsibilities under the new anti-doping program." While testing both in and out-of-competition did occur, USADA says an education initiative - "including prohibited substances and methods, whereabouts requirements, the sample collection process, dietary supplement awareness, therapeutic use exemption rules, as well as the general rules and guidelines of competing clean" - was a concurrent priority.

USADA has posted the results of the first wave of tests, which is available for the public to see and use. The information is arranged by search criteria sorted by names, year, quarter and more.

According to the test results website, USADA has conducted 81 tests of 50 UFC fighters to date. UFC women's bantamweight champion Ronda Rousey has been screened the most with five tests. Thiago Alves, Bethe Correia and Antonio Silva have been tested four times. Anthony Johnson and Jimi Manuwa were tested three times.

UFC featherweight champion Jose Aldo, Andrei Arlovski, Daniel Cormier, Todd Duffee, Cezar Ferreia, Claudia Gadelha, Alexander Gustafsson, Michael Johnson, Cris Justino, Conor McGregor, Dustin Poirier and others were tested twice. Notable names like Vitor Belfort, Erick Silva, Ryan Bader, Josh Barnett, John Dodson, Dan Henderson, Johny Hendricks UFC flyweight champion Demetrious Johnson, Roy Nelson and Tyron Woodley were only tested once.

In the second and now current phase, fighters are required to have completed their whereabouts file, so fighters can be contacted and tested more easily during out-of-competition windows.

"We have had the opportunity to speak with many athletes during this initial program phase, and we have appreciated their passion for protecting clean sport and their dedication to participating in a comprehensive anti-doping program," said USADA CEO Travis T. Tygart on USADA's website. "The first three months have been right on track with the program launch plan, which necessarily included a large emphasis on the vitally important athlete education efforts. Now, with the whereabouts filing process complete, we begin the rollout of the full strategic out-of-competition testing plan."

UFC hired USADA in June of 2015 to conduct and control their anti-doping programs.
