German athletics supremo Clemens Prokop on Monday said it was natural that Usain Bolt's achievements at the Beijing Olympics were met with suspicion and voiced general concern about the fight against doping.
Bolt bettered the 100 and 200 metres world records and also got his third gold in world record time as part of the Jamaican 4x100m relay team.
The DLV president Prokop, in an interview with Deutsche Presse-Agentur dpa, referred not only to Bolt's 100m time of 9.69 seconds, but the way he ran it - by shutting down before the finish line.
"A barrier was cracked which generations of sprinters had failed to break, sprinters who were revealed to be doped. It is only natural that there is suspicion," Prokop said.
Prokop named doping "an intrinsic problem in high-performance sport." He said he was not surprised about the recent announcement from the World Anti-Doping Agency that 102 of 205 Olympic Committees did not give details about athletes' whereabouts and that the results of 300 Olympic doping tests were not available yet.
"You know that there is no equal opportunity if you know that not even 30 countries have a national anti-doping agency and many federations don't conduct out-of-competition tests," Prokop said.
