The aim of this investigation was to describe the outcomes of the adverse analytical findings in different Olympic sports. The data included were gathered from the World Anti-Doping Agency Anti-doping Rule Violations Reports (2013-2017). Weightlifting (78.1±9.4%) wrestling (73.2±18.5%) and volleyball (68.3±18.7%) were the sports with the highest proportion of cases that ended in an antidoping sanction. Gymnastics (45.1±10.1%), triathlon (32.6±11.9%) and shooting (29.9±14.1%) were the sports with a higher frequency of cases that were not sanctioned due to medical reasons. Gymnastics (22.4±18.4%), boxing (23.2±16.0%) and taekwondo (17.3.1±16.4%) presented the highest proportion of cases that are still pending resolution. The proportion of cases that ended in no sanction was higher in fencing (26.2±22.7%), skating (23.6±35.1%) and tennis (18.6±26.5%). These results indicate that the sanctions derived from antidoping rule violations were not uniform in all sports disciplines.
