These Vintage Photos Prove That Roller Derby Has Always Been Cool

Roller Derby Positions

There are three positions in roller derby: jammer, blocker, and pivot. The jammer laps the opposing team members while the blockers create a wall to protect the jammer. The pivot is a blocker who can be designated as a jam during a jam as long as their helmets are transferred properly. Pivots, who wear a stripe on their helmets, can also act as a temporary captain for the team.

Strategies

The three main strategies of roller derby are ending the jam, passing the star, and penalty-killing. Ending the jam means that the lead jammer can call off the jam at any time, which controls the opposing team’s ability to score points.
