Disciplined

McLaren’s first report, published last July, detailed how major events in Russia – including the 2013 World Athletics Championships in Moscow and the Sochi Winter Olympics a year later – had been corrupted by the Russian government, the ministry of sport and the FSB – the state security service and the successor to the KGB – who ensured those athletes who were taking banned substances did not test positive in tests.

“We are increasing the number of athletes involved, as well as the scope and conspiracy and cover-up,” he added. “A cover-up that dates back to at least 2011 and continued after the Sochi Winter Games. A cover-up that evolved over the years from uncontrolled chaos to an institutionalised and disciplined medal-winning and conspiracy. A cover-up that operated on an unprecedented scale.” (The Guardian.)

Does "disciplined" refer to the sport disciplines or to a sort of bringing the "medal-winning" under Russia state control in the paragraph above?
