CHICAGO — A federal judge ruled the world champion U.S. women’s soccer team does not have the right to strike to seek improved conditions and wages before the Summer Olympics, seeming to end the prospect of an unprecedented disruption by one of the most successful American national teams.

The case pits the U.S. Women’s National Soccer Team Players Association against the U.S. Soccer Federation, which sued in February to clarify the strike issue. U.S. District Judge Sharon Johnson Coleman ruled Friday the team remains bound by a no-strike provision from its 2005-12 collective bargaining agreement.

The federation warned a strike could have forced the women’s team, which is seeking its fourth straight Olympic gold medal in Brazil, to withdraw from the Games and said that would have damaged American soccer as a whole.

The union wanted the option of striking, though it hadn’t said definitively that it would.
