BBC Show Says Steroid Effect May Be Mental

LONDON — Anabolic steroids may have a greater effect on the minds than the bodies of athletes trying to improve their performances, a British television documentary says.

“QED: The Steroid Myth” presents evidence from the United States, Britain and Italy challenging the view that the physical effects alone of steroids can turn good athletes into world champions.

“The idea that steroids enhance performance may be another damaging myth,” the program, scheduled for airing Wednesday, concludes.

At a press briefing today, the program’s producer, Chris Thau, said the muscle-building powers attributed to steroids can help certain athletes at certain times.
