Researchers investigating whether Viagra may give athletes an unfair advantage.
In a front-page story, the New York Times (11/23, A1, Longman) reported that a study being conducted at Marywood University and financed by the World Anti-Doping Agency is investigating whether Viagra (sildenafil citrate) creates "an unfair competitive advantage in dilating an athlete's blood vessels and unduly increasing oxygen-carrying capacity." Earlier studies have found that the drug may enhance physical performance. A study "published in 2006 in The Journal of Applied Physiology" found "that some participants taking Viagra improved their performances by nearly 40 percent in 10-kilometer cycling time trials conducted at a simulated altitude of 12,700 feet -- a height far above general elite athletic competition." In addition, "a 2004 German study of climbers at 17,200 feet at a Mount Everest base camp, published in The Annals of Internal Medicine, found that Viagra relieved constriction of blood vessels in the lungs and increased maximum exercise capacity." from DIA
