Roller derby rocks!
And makes you look cool 😉
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. Game play consists of a series of short scrimmages
(jams) in which both teams designate a jammer (who uniquely
wears a star on the helmet) 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.
Modern roller derby is an international sport, mostly played by
amateurs. It was under consideration as a roller sport for the 2020
Summer Olympics.
