Why is propranolol banned in the olympics

It led to China's Zonglian Tan being promoted to the 50m pistol silver, with Vladimir Isakov now taking the bronze. The air pistol bronze now goes to the US's Jason Turner.

I interpret that it was a deliberate intake because of the importance it has in that sport. The consequences are obvious. Kim's positive test was the second of these Games after the Spanish road cyclist Maria Isabel Moreno was stripped of her Olympic accreditation on Tuesday.

A steady hand, free of nervous twitches is crucial for success in shooting. And beta blockers can provide that in pressure situations. But it remains a substance banned for all sports in-competition, but prohibited for out-of-competition use by only archery and shooting — both precision sports. The year-old belongs to a sport that, in the current era of doping scandals, has a remarkably clean record. Till date, shooting has recorded just two doping episodes — North Korean Kim Jong-su and Russian Sergei Alifirenko tested positive in seperate incidences in Kim, incidentally, was banned for the use of propranolol — a beta blocker.

Sports-wise nobody uses anything. The nature of the sport reduces any use of high performance supplements, thereby curtailing the confusion or ambiguity on whether the supplement is safe to have or not. Having such a clean record in the sport means that shooters keep a strict watch on everything they have to consume, be it food or prescribed medicines. Wait a second, I take a beta-blocker for high blood pressure.

Does that mean I can't be an Olympic shooter? Already a subscriber? Sign in. Thanks for reading Scientific American.
