5 Athletes Test Positive For Doping

ATHENS, Greece -- The World Championships began and ended with a recurring theme: doping.

Ukrainian shot putter Aleksandr Bagach was an opening-day winner who had his title taken away for testing positive for a stimulant. On the 10th and final day, Russian silver medalist Olimpiada Ivanova had her medal stripped for allegedly taking steroids.

A total of five athletes had tested positive for drugs by Sunday's close of the 10-day championships, with about 50 more controls still to be analyzed.

In the latest cases, two Russian women -- including 10,000 meters walk silver medalist Ivanova -- had their results annulled and were given two-year bans because of positive tests for the steroid stanozolol.

That announcement Sunday came three days after Bagach lost his gold medal for testing positive for a stimulant, ephedrine.

Ivanova, 27, won her silver medal Thursday, finishing behind Italy's Annarita Sidoti in the 10,000 meters, but now will have to return her $30,000 prize money.

The other Russian handed a two-year ban Sunday was 800 meters runner Liubov Tysoma, who failed to finish her semifinal heat.

Along with Bagach -- whose disqualification gave John Godina of the United States a second straight world shot put title -- the others who tested positive for ephedrine were French hurdler Pascal Maran and Kazakstan triple jumper Oksana Zelinskaya, neither of whom made the finals of their events.
