What is a "block" in roller derby?

In roller derby, a "block" refers to an action taken by a player to impede the movement of an opponent. This is a fundamental aspect of the game, as blocking is essential for both offensive and defensive strategies. By using their body, skaters can create physical barriers that disrupt an opponent’s speed and trajectory, making it challenging for them to navigate the track or score points. Effective blocking can involve shoulder checks, hip checks, or simply positioning oneself strategically to limit an opponent’s options.

This skill is crucial for maintaining control of the game and can significantly influence the outcome of plays as teams work together to protect their scoring players (the jammers) while also trying to hinder the opposing team's jammer. Understanding and executing blocks effectively is a key component of roller derby tactics.
