Researchers reported on the eve of the 2006 Tour de France, which gets under way in Strasbourg on July 1, that cyclists may be able to increase their athletic performance by taking Viagra, a drug most commonly used to treat male impotence.
Certain cyclists have more trouble than others in sustaining high levels of exertion at mountainous elevations, but the study, to be published in the Journal of Applied Physiology, found that Viagra could boost a rider's athletic performance by 45 per cent.
The cyclists were tested on an exercise bike both under normal conditions and while breathing air low in oxygen. Some were given Viagra while others were given a sugar pill placebo.
"The participants told us that while they were riding the bike they didn't know whether they were on the drug or not," Dr Friedlander said.
"However, what they did say was that in the showers afterwards they pretty much knew which pill they had been given." Viagra was originally launched as a medication for pulmonary hypertension, which occurs when blood vessels in the lungs constrict, decreasing the amoViagra counteracts these effects because it dilates blood vessels, thus relieving constrictions in the vessels and allowing blood to flow more freely through some organs in the body.
Viagra is not listed as a banned drug by the World Anti-Doping Agency, but Sean Petty, chief of staff for USA Cycling, the organisation that oversees competitive bike racing in the US, said "if it's determined at some point to be a performance-enhancing drug, I'm sure it will be on the banned list".
Dr Friedlander, however, has a hunch that some athletes are already taking Viagra for competition, possibly including cyclists competiting in Le Tour next month.
"Cyclists are always looking for that competitive edge," she said.
"They are scanning for anything, and it's conceivable that they might be taking it already."

This should be very interesting news to the World Anti-Doping Agency who’s president is named- and I’m not kidding here- Dick Pound.
Classic.
