What does a 'star pass' involve in roller derby?

A 'star pass' in roller derby specifically refers to the maneuver in which the jammer transfers the star helmet cover to the pivot. This action is critical in the dynamics of gameplay because it allows the pivot, who is usually a strong blocker, to become the new jammer. This can occur when the original jammer is unable to continue scoring for various reasons, such as being unable to break through the pack or being assessed a penalty.

By performing a star pass, the team can retain the ability to score points and leverage the pivot’s skills in navigating through the opposing team's blockers. This strategic move can help maintain scoring momentum and adapt to the changing dynamics of the game.

The other choices involve aspects of play that do not accurately define the specific action of a star pass. Blocking techniques and strategies for increasing endurance are important in the game but do not relate to the direct action of transferring the star cover. Scoring points through the actions of blockers also doesn’t pertain to the core concept of a star pass.
