Mary Decker - Doping Controversy

Doping Controversy

In 1996, at the age of 37, as she qualified for the 5000 meters at the Atlanta Olympics, Decker became involved in controversy. A urine test taken in June at the Olympic Trials showed a testosterone to epitestosterone (T/E) ratio greater than the allowable maximum of six to one. At the time of the positive test Decker was being coached by Alberto Salazar.

Decker and her lawyers contended that the T/E ratio test is unreliable for women, especially women in their late 30s or older who are taking birth control pills. In the meantime, Decker was eliminated in the heats at the Olympics.

In June 1997, the IAAF banned Decker from competition. In September 1999, a USATF panel reinstated her. The IAAF cleared her to compete but took the case to arbitration. In April, 1999, the arbitration panel ruled against her, after which the IAAF – through a retroactive ban, even though she was cleared to compete – stripped her of a silver medal she had won in the 1500 meters at the 1997 World Indoor Championships.

In April 1999, Decker filed suit against both the IAAF and the U.S. Olympic Committee which administered the test, arguing that the test is flawed and cannot distinguish between androgens caused by the use of banned substances and androgens resulting from the use of birth control pills. The court ruled that it had no jurisdiction, a decision which was upheld on appeal.

Due to its history of false positives, especially among older female athletes, the (T/E) ratio test has since been revised and laboratories now also run a carbon isotope ratio test (CIR) if the ratio is unusually high.
