4,027 is the number of Russian athletes included on the list of those banned from international competition, published on the official website of the International Association of Athletics Federation (IAAF) on Feb. 8 .
The list is based on data obtained from the World Anti-Doping Agency (WADA) and has no exemptions: Among those excluded from competition are world-famous Olympians such as two-time Olympic gold medalist and three-time world champion Yelena Isinbayeva, who is seen as the greatest female pole-vaulter in history.
Background:
On Nov. 9, WADA's independent commission presented a report in which it accused the Russian authorities of covering up positive doping tests of athletes.
On Nov. 13, following a recommendation from WADA, the Council of the International Association of Athletics Federations (IAAF) decided to suspend Russia from the competitions under its auspices, including the Olympic Games in Rio de Janeiro in 2016.
