Question: 1 / 445

Which energy system predominates in a 200-400 m sprint?

ATP-CP (phosphagen) system

Anaerobic (glycolytic) system

The anaerobic (glycolytic) system predominates in a 200-400m sprint because it provides a high rate of ATP production, allowing the muscles to keep contracting at a high intensity for a short period of time. The ATP-CP system (choice A) only provides energy for about 10 seconds, so it would not be efficient for a longer sprint. The aerobic (glycolytic) system (choice C) relies on oxygen and is more suited for long distance endurance activities. The fatty acid oxidation system (choice D) is also more suited for endurance activities and does not produce ATP quickly enough for a sprint.
