The I.H.F. requires that women wear bikini bottoms “with a close fit and cut on an upward angle toward the top of the leg.” The sides of the bikini bottoms must be no more than four inches. Men, on the other hand, can wear shorts as long as four inches above their knees as long as they are “not too baggy.”
Norway’s handball federation last week proposed that the I.H.F. scrap its bikini bottom rule, citing the double standard in attire for male and female athletes. “The players should have two to four options to choose from,” the proposition recommends.
So far, the I.H.F., which is based in Basel, Switzerland, has said it could not make any changes until its international conference in November.
The federation decided to require that female players wear bikini bottoms because those were the rules for beach volleyball, which is played on the same surface, Mr. Moustafa said in a statement.
The I.H.F. also said it was “unfortunate” that the Norwegian players wore shorts, against league rules, during the Olympics.
“Due to the timing of their protest and campaign, the achievements of the athletes were simply overshadowed,” the organization said.
The Danish Handball Federation, in a letter to the I.H.F. in May, wrote that several Danish players had decided not to compete in this year’s tournament because they felt ill at ease in bikinis.
