Athletic Federation of Serbia within the framework of its program of activities organized “Days of athletics” in Zrenjanin on 12 and 13 November 2016. Representatives of ADAS gave a lecture on the first day of the seminar entitled “Athlete Biological Passport”. Coaches have heard about hematological and steroid passport who are the future of the fight against doping. Proof that the issue was more than the atractive is the fact that the discussion lasted almost as long as lecture. ADAS continues good cooperation with the Athletic Federation of Serbia.
