Which of the following is an important factor in developing endurance for roller derby?

Regular cardiovascular training is a crucial element in developing endurance for roller derby. This type of training strengthens the heart and lungs, enhancing the body's ability to deliver oxygen to the muscles during prolonged physical activity. As roller derby matches are often dynamic and can be physically demanding, having a well-developed cardiovascular system allows players to sustain their energy levels throughout the game, recover faster during rests, and maintain performance even under fatigue.

Incorporating various forms of cardiovascular exercise, such as running, cycling, or interval training, into a training regimen can significantly improve overall fitness, which directly translates to better endurance on the track. This enables skaters to keep up with the fast pace of the game, make quick movements, and execute plays effectively, ultimately making endurance a key factor for success in roller derby.
