What is the purpose of agility drills in roller derby practice?

The purpose of agility drills in roller derby practice centers on enhancing quick directional changes and overall nimbleness, which are critical skills for a roller derby athlete. In a fast-paced game where skaters must adjust their movements rapidly to respond to opposing players, the ability to pivot, swerve, and change direction is essential. Agility drills train the body to react swiftly and efficiently, enabling athletes to navigate the track effortlessly, evade blockers, and position themselves effectively during gameplay.

While building physical strength and preparing for endurance could be important aspects of a roller derby athlete's training regimen, they do not directly address the quick movements and responsiveness required on the track in a game. Similarly, a focus solely on offensive maneuvers neglects the equally vital defensive skills that agility drills promote. Overall, agility drills are specifically designed to enhance the quickness and versatility of skaters, making option A the most fitting answer.
