New Suspect in Sports Doping Is, No Joke, Viagra

SCRANTON, Pa. — When George Downey volunteered along with other lacrosse players at Marywood University to take Viagra for a study, he received a snickering nickname from his high school coach. His parents jokingly told their friends. Inquiring minds sent messages to his Facebook page.

“They’re making fun of me,” Mr. Downey, 19, said good-naturedly. “Deep down, I think they’re looking for tips.”

Except that the Marywood study does not involve the bedroom, but the playing field. It is being financed by the World Anti-Doping Agency, which is investigating whether the diamond-shaped blue pills create an unfair competitive advantage in dilating an athlete’s blood vessels and unduly increasing oxygen-carrying capacity. If so, the agency will consider banning the drug.

Viagra, or sildenafil citrate, was devised to treat pulmonary hypertension, or high blood pressure in arteries of the lungs. The drug works by suppressing an enzyme that controls blood flow, allowing the vessels to relax and widen. The same mechanism facilitates blood flow into the penis of impotent men. In the case of athletes, increased cardiac output and more efficient transport of oxygenated fuel to the muscles can enhance endurance.
