Paris: The sensation of 400 meters 18-year-old Christine Mboma will be banned from the event at the Tokyo Olympics because of the elevated testosterone level, the Namibia Olympic Committee said on Friday.
Mboma runs one round of the seventh fastest woman in history when she recorded 48.54SEC in the city of Poland bydgoszcz on Wednesday.
Namibian NOC said Mboma and compatriot Beatrice Masilingi, also 18, had been tested at a training camp in Italy.
“The results of the test center show that the two athletes have a natural high testosterone level,” the Committee said in a statement.
“It is important to understand that our athletes are not aware of this condition” and their families or their coaches.
World athletics prohibit women who have high-level testosterone, which gives them additional strength, from competing in races between 400 m and one mile unless they undergo treatment to reduce the level.
Under the same rule, the South African Olympic champion champions will be banned from defending his 800m title in Tokyo.
Mboma and Masiilingi will still be able to compete at 200 m in the Olympics, although their best time in the event does not put them in a dispute for medals.
