On July 17, 2015, the swimmer Yana Martynova (RUS) was tested positive to the prohibited substance Ostarine (Class S.1.2 Other Anabolic Agents) following an out-of-competition doping control test conducted by RUSADA.

RUSADA imposed a sanction of 4 years’ ineligibility on the athlete starting on July 27, 2015, the day of her provisional suspension. The swimmer appealed this decision to the National Appeal Body who ultimately upheld RUSADA’s decision.
