A pair of Indonesian swimmers have received three-month suspensions after positive tests at the 2013 Asian Indoor and Martial Arts Games that took place in Incheon, South Korea in late June/early July.
Indra Gunawan will have to forfeit his gold medal from that meet, won in the 50 short course meters breaststroke (27.29). He is currently training in Hungary, according to Indonesian news site Liputan6, and said “Any decision LADI (the Indonesian Anti-Doping Agency) makes, I will appreciate and obey.”
Guntur Pratama, who took a silver medal as part of Indonesia’s men’s 200 free relay and a bronze on the 400 free relay, will receive the same suspension.
Both positive tests have been blamed on methylhexaneamine in the supplement JACK3D. Methylhexaneamine is a vasoconstrictor which can make the blood vessels more narrow. This is seen as a potential advantage in periods of training, as it can force muscles to become more efficient.
The Indonesian swimming federation says that it will begin keeping closer tabs on what supplements its athletes are taking.
The three-month suspensions will leave both swimmers eligible in time for the 27th South East Asian Games that begin in December in Myanmar: a major multi-sport event.
