Juan Antonio Samaranch, the IOC's president, said the 11 days of talks in the French capital had strengthened the feeling that athletes should have a greater role in the Olympic movement.
Samaranch defended the IOC against criticism that the new members were all men and that only five women have seats on the committee. He said no women had been proposed for admission, but he expected more to join.
One surprise exclusion from the new members was the veteran anti-apartheid campaigner Sam Ramsamy, the man who brought South Africa back into the Olympic fold. But Samaranch said he would probably nominate a new member for South Africa - widely expected to be Ramsamy - after visiting the country later this year.
