Isabela de Padua Accepts Sanction for Violation of UFC Anti-Doping Policy

ufc gloves laying on matUSADA announced today that Isabela de Padua, of Sao Paulo, Brazil, has accepted a two-year sanction for a violation of the UFC® Anti-Doping Policy after testing positive for a prohibited substance.

De Padua, 28, tested positive for 19-norandrosterone (19-NA), the main urinary metabolite of nandrolone (19-nortestosterone) and other 19-norsteroids following an in-competition test on November 16, 2019 where she lost by unanimous decision and an out-of-competition urine test conducted on December 19, 2019. In accordance with standard practice, the exogenous, or non-natural, origin of the 19-NA was further confirmed by sophisticated carbon isotope-ratio mass spectrometry (GC/C/IRMS) analysis, which can reveal the presence of anabolic agents. In this case, the GC/C/IRMS analysis result was consistent with the exogenous origin of 19-NA. 19-norsteroids, including nandrolone and its precursors, are non-Specified Substances in the class of Anabolic Agents and prohibited at all times under the UFC Anti-Doping Policy and UFC Prohibited List.

Upon being added to the UFC Anti-Doping Program, athletes are required to declare all medications and supplements they have used in the previous 12 months. An athlete who declares the prior use of a prohibited substance will not be deemed to have committed a violation but, depending on the substance, may be required to refrain from competition for a period of at least six months and provide at least two negative samples. De Padua did not declare the use of nandrolone, or any 19-norsteroids, on her onboarding declaration forms.

De Padua’s two-year period of ineligibility began on November 16, 2019, the date her first positive sample was collected. As the regulatory body that sanctioned de Padua’s bout on November 16, 2019, the Comissao Atletica Brasileira de MMA (CABMMA) has recognized USADA’s sanction subject to any additional fines it may impose in accordance with the CABMMA Anti-Doping Policy.

USADA conducts the year-round, independent anti-doping program for all UFC athletes. USADA is an independent, non-profit, non-governmental agency whose sole mission is to preserve the integrity of competition, inspire true sport, and protect the rights of clean athletes. In an effort to aid UFC athletes, as well as their support team members, in understanding the rules applicable to them, USADA provides comprehensive instruction on the UFC Anti-Doping Program website (https://UFC.USADA.org) regarding the testing process and prohibited substances, how to obtain permission to use a necessary medication, and the risks and dangers of taking supplements, as well as performance-enhancing and recreational drugs.

In addition, the agency manages a drug reference hotline, Drug Reference Online (https://UFC.GlobalDRO.com), conducts educational sessions, and proactively distributes a multitude of educational materials, such as the Prohibited List, easy-reference wallet cards, and periodic athlete alerts. Many of the resources available to athletes are provided in multiple languages, including Russian, Spanish, French, Portuguese, Korean, and Japanese.

Along with education and testing, robust anti-doping programs enable investigations stemming from tips and whistleblowers. USADA makes available a number of ways to report the abuse of performance-enhancing drugs in sport in an effort to protect clean athletes and promote clean competition. Any tip can be reported using the USADA Play Clean Tip Center, by email at playclean@usada.org, by phone at 1 877-Play Clean (1-877-752-9253), or by mail.
