THE HAGUE, Netherlands (AP) -- An independent commission that investigated doping by Dutch cyclists and their teams recommended Monday that the responsibility for testing and sanctioning riders be taken away from the International Cycling Union to prevent the appearance of a conflict of interest.

The commission's report concluded that doping was endemic among Dutch cyclists for years and was only reduced by the introduction of measures such as biological passports and out-of-competition testing.

Doping has overshadowed Dutch cycling for years. Rabobank last year announced it was pulling out of its long-term sponsorship of the country's highest-profile men's professional team and in March former rider Michael Boogerd admitted doping during his career.

The Anti-Doping Approach Commission established by the Dutch Olympic committee and cycling union conducted anonymous interviews with dozens of riders and team staff.
