Roller derby

 Roller derby is a roller skating contact sport played by two teams of fifteen members. Roller derby is played by approximately 1,250 amateur leagues worldwide, mostly in the United States.[2]Game play consists of a series of short scrimmages (jams) in which both teams designate a jammer (who wears a unique designation on the helmet; currently a star) and four blockers to skate counter-clockwise around a track. The jammer scores points by lapping members of the opposing team. The teams attempt to hinder the opposing jammer while assisting their own jammer—in effect, playing both offense and defense simultaneously.
