Earlier this year, several football players in Lillestrøm and Vålerenga tested positive for the banned central stimulant DMBA after a match on the artificial turf pitch in LSK-hallen in Lillestrøm.
The elevated levels could be traced to the rubber granules in the artificial turf.
400-meter hurdles star Karsten Warholm trains during autumn and winter in the indoor hall Valhall in Oslo, where the same artificial turf surface is found. But Warholm is not worried about being caught for doping.
The message I have received is that you are only tested for it (DMBA) in competition and the half-life is short, meaning that the substance leaves the system quickly. As long as you are not competing, there should be no problems, says Warholm, whose competition season is over for this year.
I feel calm.
