D)the ATP-CP system exclusively.

Question

Quizplus · Accepted Answer

The high intensity of a maximal 400-meter race demands energy from a combination of both aerobic and anaerobic metabolism. While aerobic metabolism provides sustained energy over a longer duration, it cannot generate ATP quickly enough to meet the demands of a high-intensity sprint. Therefore, anaerobic metabolism provides the majority of the energy needed for the race, with the ATP coming from anaerobic sources such as the breakdown of creatine phosphate (ATP-CP system) and glycolysis.
