The World Anti-Doping Agency (WADA) said yesterday it had signed agreements with 19 Olympic international sports federations to conduct out-of-competition tests.
But nine federations, including FIFA and the International Tennis Federation (ITF), are still engaged in negotiating terms with the newly-created agency.
"We hope the remaining federations will follow suit as soon as possible," said WADA chairman and IOC vice-president Dick Pound.
While federations such as the IAAF (International Amateur Athletic Federation), UCI (International Cycling Union) and FINA (International Swimming Federation) have supported WADA, others such as FIFA have been slow to comply.
A recent study commissioned by FIFA showed that, when under stress, higher levels of the banned hormone nandrolone could be produced naturally in the body above the current IOC threshold that would result in sanctions.
The following is a list of federations which have signed agreements with WADA:
AIBA (boxing), FEI (equestrian), FIBA (basketball), FIC (canoeing), FIH (hockey), FILA (wrestling), FINA (swimming), FISA (rowing), FITA (archery), IAAF (athletics), IBF (badminton), IJF (judo), ISAF (sailing), ISF (softball), ISSF (shooting), ITTF (table tennis), ITU (triathlon), UCI (cycling), WTF (taekwondo).
The federations that have not signed contracts with WADA are: FIE (fencing), FIFA (soccer), FIG (gymnastics), FIVB (volleyball), IBAF (baseball), IHF (handball), ITF (tennis), IWF (weightlifting), UIPM (modern pentathlon).
