Bodybuilders undergo 'lie' tests

Version 0 of 1.

Bodybuilders at a national championship event have undergone mandatory lie detector tests in a bid to restore the sport's tarnished reputation.

The federation which runs the sport is determined to eliminate the use of steroids and other banned substances.

Each competitor in the British Natural Bodybuilding Championships in Edinburgh has taken a lie detector test.

The winners of the contest will still have to take conventional drug tests and there will also be random sampling.

Organisers and competitors said the lie detector tests proved that the issue of drug abuse and cheating was being taken seriously.
