Lance Armstrong's doping confession to Oprah Winfrey was "too little, too late" and failed to provide any new information that will help clean up the sport he tarnished through years of cheating, the vice president of the International Olympic Committee said Friday.

A day after stripping Armstrong of his bronze medal from the 2000 Sydney Olympics, the IOC urged the disgraced former Tour de France champion to supply details to anti-doping authorities in order to "bring an end to this dark episode."

In an interview with The Associated Press, IOC vice president Thomas Bach said Armstrong's admission to Winfrey that he used performance-enhancing drugs — after years of vehement denials — was not enough.

Conspiracy Theories

Former UCI resident Hein Verbruggen says allegations he helped cover up Lance Armstrong's doping were shown as "conspiracy theories" by the rider's interview with Oprah Winfrey.

Verbruggen says in a statement he is "pleased that after years of accusations being made against me, the conspiracy theories have been shown to be nothing more than that."

The Dutch official, who led the UCI from 1991-2005, has "no doubt that the peddlers of such accusations and conspiracies will be disappointed by this outcome."

Armstrong told Winfrey that former teammates' testimony about the UCI making a positive test at the 2001 Tour of Switzerland "go away" was untrue.

Armstrong said money he gave the UCI was "not in exchange for help."

Verbruggen says he's "not surprised that Lance Armstrong confirmed this."

"If he thinks this interview would help him get credibility back, I think this is too little, too late," said Bach, a German lawyer who leads the IOC's anti-doping investigations.

"It's a first step in the right direction, but no more. If he really loves his sport and wants to regain at least some credibility, then he should tell the whole truth and cooperate with the relevant sports bodies."

Armstrong is under pressure to come clean to the World Anti-Doping Agency, the U.S. Anti-Doping Agency and the independent commission set up the International Cycling Union.

"We have three sports bodies he can address," Bach said by telephone. "He needs to give testimony under oath.

"After lying for more than a dozen years, he needs to be questioned by experts and not just in a well-orchestrated interview."

In a statement from Lausanne, Switzerland, the IOC said: "We now urge Armstrong to present all the evidence he has to the appropriate anti-doping authorities, so that we can bring an end to this dark episode and move forward stronger and cleaner."

In the interview with Winfrey, Armstrong acknowledged that he used EPO, testosterone, human growth hormone and blood transfusions in order to win the Tour de France seven times.

"This is not enough," said Bach, who is a leading contender to succeed Jacques Rogge as IOC president in elections in September.

"I hoped he would be more precise, that you would get an idea of who were the people behind him. He's even protected the famous Dr. Ferrari."

Bach was referring to Italian doctor Michele Ferrari, who worked closely with Armstrong and has been accused of being a mastermind of the cyclist's doping program.

"In some parts of the interview, he was pretty evasive, in some parts contradicting himself," Bach said.

Bach said the interview offered no information beyond the USADA report that detailed widespread doping by Armstrong and his teammates and led to the stripping of his Tour titles and a lifetime ban from Olympic sports.

"We have no new facts — not a single new fact going beyond the USADA report," Bach said.

'Still hope for a full inquiry'

Armstrong denied in the interview that cycling body UCI covered up positive tests or helped him avoid detection.

Bach said the interview provided no allegations that would put cycling's Olympic status in jeopardy. Senior Canadian IOC member Dick Pound, a former head of WADA, suggested this week that cycling could be kicked out of the Olympics if there was proof of UCI collusion with Armstrong.

"I still hope for a full inquiry, but, in general, you have to consider the anti-doping system since then has changed very much for the better," Bach said. "The UCI has introduced the blood passport.

"There is more target testing and out-of-competition testing and better methods for detecting EPO. You cannot draw conclusions from 10 years ago."

In Lausanne, the IOC said it "unreservedly condemns" the actions of Armstrong and all drug cheats.

"This is, indeed, a very sad day for sport, but there is a positive side if these revelations can begin to draw a line under previous practices," the statement said. "It is the IOC's firm expectation that all parties involved will draw the necessary lessons from this case and continue to take all measures to ensure a level playing field for all athletes."

'A big first step'

Armstrong's former teammate, Tyler Hamilton, calls the cyclist's confession a "big first step" but says Armstrong must follow it up by telling authorities everything he knows about the doping programs he used to win his Tour de France titles.

Hamilton's testimony was key to the case against Armstrong. He described the doping program on Armstrong's team and the power Armstrong wielded in pressuring teammates to go along with the doping.

About 12 hours after watching Armstrong's interview with Oprah Winfrey, Hamilton told The Associated Press: "He's broken. He's broken." 

Hamilton insisted he'd never seen Armstrong act the way he acted in the interview.

Hamilton rode with Armstrong on the U.S. Postal Service team from 1998 to 2001.
