Answer
For the 400 meters, which takes approximately 45 seconds and is performed at a high intensity, the primary energy system utilized is the Anaerobic Lactic system (or Anaerobic glycolysis). This system provides energy without the need for prolonged oxygen intake, suitable for short bursts of high intensity.

Answer
In the case of the long jump, where the duration is between 3 to 5 seconds and the intensity is high, the main energy system engaged is the Anaerobic ATP-PC system (or anaerobic alactic system). This system produces immediate energy for short, explosive activities.
