Sin City Rollers Geraldton Roller Derby

Roller derby is a full contact sport played by two teams of five skaters moving anti-clockwise around an oval track. Game play consists of a series of short match-ups ("jams") in which both teams designate 1 scoring player each (the "jammers") who scores points by lapping the other 4 members of the opposing team (the "blockers"). The teams attempt to assist their own jammer while hindering the opposing jammer — in effect playing both offense and defense simultaneously. Roller derby is played by more than 1,200 amateur leagues on every inhabited continent. While the sport has its origins in the banked-track roller skating marathons of the 1930s, Leo Seltzer and Damon Runyon are credited with the basic evolution of the sport to its initial competitive form. Professional roller derby quickly became popular; in 1940 more than 5 million spectators watched bouts in 50 US cities. Modern roller derby is an international sport dominated by all-female amateur teams, in addition to a growing number of male, co-ed, and junior roller derby teams, and is (as a roller sport) under consideration for the 2020 Olympics. Most modern leagues share a strong D.I.Y. ethic which uniquely combines athleticism and alternative elements and third-wave feminist aesthetics.
