"We have to have girls who, when the whistle blows, they don't run, they don't swim. They stand up on the block and they don't go," said Gaines.
"It's unfortunate, of course, to ask women to make that sacrifice because these are their sports, they should be entitled to playing," she added. "They shouldn't have to give up anything to get changes."
