As stated in this press release, Swimming South Africa has been informed that during the FINA Swimming World Cup in Belo Horizonte (BRA), swimmer Keri-Leigh Shaw tested positive for the substances Clenbuterol and Ephedrine.
Clenbuterol and Ephedrine are decongestants and bronchodilators used by for instance people with astma. Clenbuterol is also a non-steroidal anabolic and metabolism accelerator, and Ephedrine an amphetamine-like stimulant, which is probably why they are classified as doping.
Ms. Keri-Leigh Shaw is now provisionally suspended until a hearing before the FINA Doping Panel can be made, following the analysis of the B-sample.
