Performance enhancing drugs used by athletes
Though glamorous, athletics is also controversial with athletes often being accused of using performance enhancing drugs and steroids. The regulatory body will carry out drug tests on athletes especially the winners at the Olympics and other sports meets.
While the banning of a large number of Russian athletes from the Rio Olympics is the latest in the long history of authorities tried to prevent drug usage, there are many famous athletes who allegedly used performance enhancing drugs to boost their performance.
Only recently in 2017, the Russian tennis star Maria Sharapova resumed playing professional tennis, after she was banned for taking a prohibited substance.
