Sprinters that have served bans for intake of steroids desire to manifest that they can win without steroid use

2 runners that have served suspensions want to display that they can win without application of steroids. They are going to take part in the 2012 London Olympics. Justin Gatlin, an American sprinter, and Dwain Chambers, a British sprinter, want to show that they may win, competing clean.
They have already manifested that they are worthy to be called “Olympic champions”. While Justin Gatlin has obtained the gold medal, Dwain Chambers has obtained the bronze medal in the 60 meter sprint a1t the 2012 World Indoor Athletics Championship in Turkey.
Justin Gatlin was invited to professional sports again by the USA Track and Field and the US Olympic Committee. These two agencies noted about their attitude to this runner, supporting him.
When it comes to Dwain Chambers, it is not clear yet whether he will be allowed to participate in the Olympics. This sportsperson wasn’t so supported, as Justin Gatlin was. Chambers received cold response from the British Olympic Association (BOA). Chamber’s return to sports induced the decision of the BOA to suspend sportspersons that have been caught using steroids from the Olympics forever.
The World Anti-Doping Agency has informed the BOA that this rule violated the WADA laws connected with forbidden drugs. 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).
so, while Justin Gatlin was supported by the US Olympic Committee, Chambers’ case wasn’t pleasant.
Justin Gatlin has never admitted that he had taken steroids intentionally. But Chambers took the whole responsibility for application of steroids.
The American sprinter tested positive for testosterone in April 2006. This athlete’s world record was annulled after the results of testing had been reported. At the beginning this athlete was banned for 8 years. Later his suspension was reduced to 4 years due to cooperation with the USADA.
Justin Gatlin didn’t admit that he had utilized steroids intentionally. He blamed his masseuse for application of a testosterone cream during a massage.
On the contrary, Chambers acknowledged that he had utilized steroids and taken the complete responsibility for the violation of steroid rules. He was sentenced to 2-year ban. This runner lost all medals he obtained since 2002.
Different attitudes to these sprinters have displayed the difference between perceptions of athletes who have applied steroids by anti-doping officials in the USA and in the UK.
