While sports organizations of the USA have supported Gatlin’s return to professional sports, the BOA has decided to prevent participation of Dwain Chambers in the Olympics

2 sprinters that have served suspensions want to manifest that they can compete successfully without usage of steroids. They want to take part in the 2012 London Olympics. Justin Gatlin, an American sprinter, and Dwain Chambers, a British sprinter, desire to display that they can win, competing clean.
They have already demonstrated that they are worthy to be called “Olympic champions”. While Justin Gatlin has won the gold medal, Dwain Chambers has received the bronze medal in the 60 meter sprint a1t the 2012 World Indoor Athletics Championship in Turkey.
The USA Track and Field and the US Olympic Committee invited Justin Gatlin to professional sports. These 2 organizations noticed about their attitude to this sprinter, supporting him.
As for Dwain Chambers, it is unclear yet whether he will be permitted to take part in the Olympics. This runner wasn’t so supported, as Justin Gatlin was. Chambers received cold response from the British Olympic Association (BOA). This athlete’s comeback to sports prompted the decision of the BOA to suspend athletes that have been caught using steroids from the Olympics forever.
The World Anti-Doping Agency has warned the BOA that this rule violated the WADA laws linked with forbidden products. The BOA decided to fight against WADA and to prevent participation of Dwain Chambers for the United Kingdom in the Olympics. The BOA has taken the case to the Court of Arbitration for Sports (CAS).
Thus, while Gatlin was supported by the US Olympic Committee, Chambers’ case was not pleasant.
Justin Gatlin has never admitted that he had used steroids knowingly. But Chambers took the full responsibility for intake of steroids.
Gatlin tested positive for testosterone in April 2006. This athlete’s world record was annulled after the results of testing had been pronounced. At the beginning this sprinter was banned for eight years. Later his ban was reduced to 4 years because of cooperation with the USADA.
Gatlin didn’t acknowledge that he had utilized steroids intentionally. He blamed his masseuse for application of a testosterone cream during a massage.
On the contrary, Dwain Chambers admitted that he had administered steroids and taken the whole responsibility for the violation of steroid rules. He was banned for 2 years. This runner lost all medals he won since 2002.
Different attitudes to these runners have demonstrated the difference between perceptions of athletes who have used steroids by anti-doping officials in the USA and in the UK.
