Oct. 4, 2009— -- It may not be an Olympic sport -- at least not yet -- but that's not stopping the women of roller derby from raising the stakes in this competitive, and often rough, sport.
Long before Barrymore was cast as a free-spirited Texan who takes up the skates in a quest to find her identity, Hollywood was enamored with roller derby women.
"I love hitting girls on roller skates," said Kristen "Krissy Crash" Adolfi, laughing. "Where can you find this many powerful women in one place who love kicking the crap out of each other."
"You fall in love with it, getting out aggression, being tough but yet sexy at the same time," another roller derby contestant said.
Roller derby began in the 1930s, but it wasn't until the 1970s that it became "theatrical" and really captured the attention of the country, said Rebecca Ninburg, owner of the LA Dolls Roller Derby.
"In the Depression, there was sort of this revival of these relay races on skates," Ninburg said. "They would start fighting and the crowd would go crazy. It remained popular in the '50s and '60s and the '70s, and in the 70's it started becoming really theatrical."
The rules of the game are simple. There are five players from two teams, each with four blockers and one "jammer," who is identified by a star on her helmet. It's the jammer's job to break through the pack and score points, for which she has 60 seconds.
But what sets this sport apart from others is that hitting is allowed, although there are penalties for illegal hits, such as elbowing. The entire game consists of two halves, each of which has two 12-minute periods.
"There's nothing like going and hitting somebody, having them hit the ground," Jennifer Plum, who goes by the name "Hanna Belle Lector" and plays for the Minnesota RollerGirls, told The Associated Press. "Watching people stand up and scream. It's fantastic."
