Namibian teenager Christine Mboma – who broke the 30-year-old world 400m Under-20s record on Wednesday – is out of the event at the Olympics after being found to have naturally-occurring testosterone levels beyond those specified by World Athletics.
The time set by 18-year-old Namibian teenager Mboma on Wednesday in Poland was the seventh-fastest 400m run by a woman of all time – and suggested she was a prime candidate for gold in the event at Tokyo.
But Namibia’s national Olympic committee has now confirmed both sprinters are unable to run the distance in Tokyo because of World Athletics rules on “Athletes with Differences of Sexual Development”, or DSD, following testing conducted by the global body.
