JOHANNESBURG - Tests for banned substances will be more stringent than ever for the 2014 Winter Olympics, the new International Olympic Committee (IOC) president said Wednesday. Athletes will undergo 1,269 pre-competition tests -- over 400 more than the Vancouver games -- while total tests will increase by almost 300 to 2,453, said the IOC's Thomas Bach. "We shall be smarter and tougher in our fight against doping than at any previous Olympic Winter Games," he told delegates at the World Conference on Doping in Sport in Johannesburg. Bach, who replaced Jacques Rogge as Olympic chief in September, supported more stringent bans for athletes caught doping. "What we need is the greatest possible deterrents. I strongly argued for a lifetime ban, even for a first doping offence," he said.–AFP
