C) oxidative
D) all of the above

Question

Quizplus · Accepted Answer

The 400m sprint is considered a middle-distance race that requires a combination of anaerobic and aerobic energy systems. However, most of the energy needed for the 400m sprint comes from the glycolytic system, which uses stored glycogen to produce energy quickly without oxygen. The phosphogen system also contributes, but only for the first few seconds of the race, while the oxidative system provides energy for the latter half of the race as the body's oxygen supply increases. Therefore, the best choice is B - glycolytic.
