BEIJING, (Pakistan Point News - APP - 12th Augst,2016) - Chinese swimmer Chen Xinyi has failed a doping test at the Rio Olympics, the official Xinhua news agency reported Friday, citing the Chinese Swimming Association (CSA). She tested positive for hydrochlorothiazide, a diuretic, on Sunday, it said. On that day the 18-year-old came fourth in the women's 100m butterfly final -- just 0.09 seconds away from a place on the podium. Chen has applied to the International Olympic Committee for her B sample to be tested and for a hearing, it added.
Diuretics increase urination rates and can be used as "masking agents" to hide the presence of performance-enhancing substances that are screened for in doping tests. The CSA "resolutely opposes use of banned substances", Xinhua cited it as saying in a statement. "The CSA has taken this matter seriously and demanded full cooperation from Chen in the investigation," it added. "We will cooperate with the Court of Arbitration of Sport during its investigation and will respect the final ruling by the CAS."
