FINA explained their decision in a statement
Swimming's governing body has banned seven Russian competitors from the Rio Games due to doping violations.
It follows the International Olympic Committee's ruling to give individual sports the decision whether they allow the country's athletes to compete.
They gave the verdict yesterday after evidence of state-sponsored doping.
FINA, which regulates swimming, diving, water polo, synchronized swimming and open water swimming, published a statement outlining their own decision to ban seven competitors.
They state: "In this context and as a decision made as an emergency in the context of Rio 2016, and in application of art. C 17.14.8, to protect the integrity of sport and the clean athletes, the FINA Bureau has decided that it will subject the eligibility of Russian athletes to specific additional criteria, such criteria being consistent with the IOC’s requirements published on July 24, 2016:
"First, no athlete corresponding to the samples mentioned in the IP Report will be declared eligible.
"Secondly, every Russian athlete’s entry will be analysed in respect of doping tests conducted either by FINA and/or other NADOs and not analysed in Russia. The FINA Doping Control Review Board will conduct a review and issue a recommendation in respect to whether Russian athletes were subject to a reliable anti-doping scrutiny, for a decision to be made by the FINA Executive.
"FINA has noted the requirement that the Russian Olympic Committee (ROC) shall not enter any athlete having been already sanctioned. Accordingly, no such athlete will be declared eligible.
"The above measure applies to the Russian Swimming Federation. As an immediate effect of the above mentioned criteria, seven swimmers are not eligible to compete at the 2016 Rio Olympic Games:
"Athletes withdrawn by the ROC:
- Mikhail Dovgalyuk
- Yulia Efimova
- Natalia Lovtcova
- Anastasia Krapivina (Marathon Swimming)
"Athletes appearing in the WADA IP Report:
- Nikita Lobintsev
- Vladimir Morozov
- Daria Ustinova."
The International Tennis Federation has already said they are happy for Russian players to participate in Brazil.
But the International Association of Athletics Federations (IAAF) had already banned Russian track and field athletes.
