Optical sensor indicates performance enhancing drug use in precision sports athletes
NewsRx.com (September 7, 2006)
Researchers at the University of Granada, directed by professors Alberto Fern & #225;ndez Guti & #233;rrez and Antonio Segura Carretero, have designed an optical sensor that indicates the presence of propanolol (a beta inhibitor used as a performance-enhancing drug in the so-called precision sports, such as motor racing or archery) in urine.
The group has worked in cooperation with the International Olympic Committee (IOC), for which the fight against drugs in the different sport disciplines is one of the main objectives.
The main contribution of their research work lies in the precision of this new system, cheaper, more accurate and, above all, faster that the old ones, as it can detect the presence of propanolol in just a few minutes, with an accuracy of 0.2 micrograms per litre.
Beta inhibitors are medicines that regulate the heart pace, slow down the cardiac frequency and stimulate the attention. They cause a reduction and improvement of pulse (reducing trembling), and they also have an anti-stress effect. Some of its undesirable effects are a sensation of permanent fatigue, a drop in arterial tension, muscular cramps, risk of psychical depression and sexual impotence if habitually and repeatedly consumed. Besides propanolol, other beta inhibitors are acebutonol, alprenolol, atenolol, labetalol, metoprolol, nadolol, oxprenolol and sotalol.
Their consumption has been banned by the IOC in precision sports such as chess, motor racing, billiards, bowling, air sports, winter sports ( & #145;freestyle aerials/half-pipe jumping, & #145;snowboard and & #145;halfpipe/big air), gymnastics, wrestling, motorcycling, p & #233;tanque, modern pentathlon, archery, & #145;curling and sailing.
