OCA medical director Mani Jegathesan has outlined today how they are implementing a "robust" anti-doping programme that has already seen 300 samples taken during the Games.

Working in partnership with National Anti-Doping Organisations from host country Vietnam, as well as South Korea and Japan, makeshift doping stations operating in tents have been set-up at all four venue clusters.

It is based on a "risk-related approach, sport by sport".

Top of this list is bodybuilding, a sport that was briefly dropped from the Asian Beach Games programme after five failed tests at Muscat 2010.

There were no failures upon its return at Phuket 2014 following special additional testing, which is also being undertaken here.

Each participating athlete has to submit a report from a WADA accredited laboratory on a specimen taken one month before the start of the Games. 

Further tests took place four days before competition began.

insidethegames understands that some athletes were barred from attending due to failures incurred in the testing one month beforehand.

It is not yet clear if any positive cases have been submitted in any sport here during the Games.

insidethegames has been told that these Games are considered a "last chance" for bodybuilding, and that the sport will be omitted from future programmes if more positive cases arise.

"In all five multi-sport events organised by the OCA, we are determined to provide a level playing field for all competitors and, in particular, to protect the clean athletes in our athlete-centered programme," said Jegathesan in an article published on the continental body's website.

"There will be no respite in our attempts to achieve doping-free games, and we will continue to work with all the relevant stakeholders at local, regional and international levels to ensure we are part of a systematic and coordinated global process."

"We also have in place a comprehensive medical programme which is being run in cooperation with the local medical services in Danang, including hospitals."

Two hundred medical encounters have been recorded at the Games so far, along with five hospital admissions.

An Ad-Hoc Commission of the Court of Arbitration for Sport is also in operation here.
