What energy system would primarily be used when performing a pole vault?

Question

Quizplus · Accepted Answer

Pole vaulting is a high-intensity, explosive event that requires a significant amount of energy to be produced in a very short period of time. The primary energy system used during a pole vault is the phosphocreatine system, also known as the ATP-PC system or the immediate energy system. This system provides energy for short-duration, high-intensity activities (usually lasting up to 10 seconds) by using stored phosphocreatine in the muscles to rapidly regenerate ATP (adenosine triphosphate), which is the energy currency of the cell.
The glycolytic system (B) is the next energy system that would contribute, providing energy for activities that last from roughly 10 seconds to 2 minutes. However, it is not the primary system used in pole vaulting due to the short duration of the activity.
The aerobic system (C) is used for prolonged activities that last several minutes to hours, and while it is always functioning to some degree, it is not the primary source of energy for the quick, explosive movements required in pole vaulting.
While all energy systems (D) contribute to overall energy production in the body and are active to some extent at all times, they do not contribute equally during a pole vault. The phosphocreatine system is the most heavily relied upon due to the nature of the activity.
