USADA announced today that Jonathan Nguyen of Chandler, Arizona, an athlete in the sport of Taekwondo, has tested positive for a prohibited substance and accepted a suspension for his doping offense.
Nguyen, 25, tested positive for methylhexaneamine, a stimulant, as a result of a urine sample collected at the US Open International competition, on February 20, 2011, in Austin, Texas. Stimulants are prohibited under the USADA Protocol for Olympic Movement Testing and the rules of the World Taekwondo Federation, both of which have adopted the World Anti-Doping Code and the World Anti-Doping Agency Prohibited List. Methylhexaneamine is classified as a Specified Substance, and therefore the presence of that substance in an athlete’s sample can result in a reduced sanction.
Nguyen accepted a six-month period of ineligibility, which began on March 29, 2011, the day he accepted a provisional suspension. As a result of the sanction, Nguyen is also disqualified from all competitive results obtained on and subsequent to February 20, 2011, the day his urine sample was collected, including forfeiture of any medals, points, and prizes.
In an effort to aid athletes, as well as all support team members such as parents and coaches, in understanding the rules applicable to them, USADA provides comprehensive instruction on its website on 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 (www.GlobalDRO.com), conducts educational sessions with National Governing Bodies and their athletes, and proactively distributes a multitude of educational materials, such as the Prohibited List, easy-reference wallet cards, periodic newsletters, and protocol and policy reference documentation.
USADA is responsible for the testing and results management process for athletes in the U.S. Olympic and Paralympic Movement, and is equally dedicated to preserving the integrity of sport through research initiatives and educational programs.
