ATHENS, Aug 4: International Olympic Committee president Jacques Rogge called on Friday for greater cooperation between governments and sports federations after two high-profile positive drugs tests by US athletes.

Floyd Landis tested positive for the male sex hormone testosterone on his way to victory in the Tour de France last month while Olympic 100 metres champion Justin Gatlin faces a life ban after a positive test for the same drug.

“We must keep up the fight against doping through strengthened concerted efforts between governments and the world of sport,” Rogge said in a statement.

“Not only to test athletes but also to educate young people about the health dangers of doping and the devastating effect it can have on a person's image and career.”

Rogge said “events of recent days are extremely disappointing in many respects”.—Reuters
