Clubs will be briefed on the AFL's plans to more strictly police the use of supplements in the next two weeks, with the AFL Commission expected to soon sign off on a long-planned set of reforms.
The league is planning to broaden its list of prohibited substances, present clubs with a list of permitted substances and suppliers, ban non-necessary injections, and rule that club doctors must sign off on every aspect of a player's treatment.
The AFL will also ensure clubs better scrutinise the qualifications of sports science and conditioning staff and ensure they improve their accountability, after learning that a dozen clubs had conducted programs involving ''medium or high levels'' of supplement use. It will present clubs with a list of prohibited treatments that cannot be used at any time, with the plan for its lists to go significantly beyond the WADA code in an attempt to discourage clubs from looking to supplements in their search for a competitive edge.
A survey of all teams, conducted after the investigation into Essendon's injecting program was launched in February, revealed that many clubs ''lacked a single point of accountability'', that their definition of supplements was not always satisfactory, and the selection process for some support personnel had been flawed.
Most dramatically, the survey revealed that players from nine clubs had independently sourced their own supplement products.
The league website reported that about 200 medical and conditioning staff were briefed on the survey results at a symposium in grand final week.
The revelations came after the Essendon supplements saga, which led to the Bombers being kicked out of the finals and coach James Hird suspended for 12 months, among other sanctions.
The ASADA investigation is ongoing, with Melbourne also to be examined over its link with sports scientist Stephen Dank, who ran Essendon's program in 2011-12.
Commentator Dr Peter Larkins, speaking on 3AW, said he found the survey results concerning. "It showed that 10 per cent of all AFL players were using a supplement, that nearly four per cent of all AFL players were using more than one supplement," he said. "And that more than two per cent of the 15 clubs had players who were using supplements that were considered 'risky or potential health risks'."
