What is an "all-out" sprint in practice drills?

An "all-out" sprint in practice drills refers specifically to a maximum effort speed drill designed to increase stamina. This type of sprint requires players to exert themselves at their highest capacity for a certain distance or duration, pushing their limits to improve both speed and endurance on the track. Incorporating such high-intensity sprints into practice helps roller derby athletes condition their bodies to sustain peak performance throughout a game, which often features quick bursts of energy and intense physical exertion.

This method of training contributes to the development of cardiovascular fitness and muscle adaptation, which are essential for the demands of roller derby. In contrast, the other options represent different aspects of training: warming up, focusing on agility, or cooling down, which are all important but serve different purposes in a training regimen. An all-out sprint specifically targets speed and stamina enhancement.
