Environmental contamination: How is that the source of inadvertent doping in sport

Unintentional doping occurs when an athlete unknowingly violates an antidoping rule, often because of using contaminated supplements, food, or medication, or due to a lack of awareness about antidoping rules.

Despite some efforts to regulate the production of food and supplements, contamination remains a concern for the athletes in the context of antidoping, because of a potential inadvertent exposure to prohibited substances.

Moreover, technological advancements in the equipment and laboratories used by antidoping bodies means that minute levels of prohibited substances can be detected in an athlete's body fluids. This had led to an increase in athletes testing positive for prohibited substances where the quantity of that substance in the athlete's sample is very low.

The purpose of the session is to show that environmental contamination (mainly of sports supplements) together with the advances in analytical technologies from the antidoping laboratories increase the number of doping cases.

After a short introduction, 3 speakers cover presentations of 20 min each, finished by a round table discussion covering questions of the audience. 

Speakers:

  • Prof Martial Saugy, UNIL
  • Dr Neil Robinson, International Testing Agency
  • Dr Tiia Kuuranne
  • Prof Franco Taroni
