The correct answer highlights that ATP (adenosine triphosphate) is the predominant source of energy during short-duration, high-intensity activities such as the vertical jump. This activity relies heavily on the immediate energy systems of the body, which include the ATP-CP (adenosine triphosphate-creatine phosphate) system.

In explosive movements like jumping, the body utilizes stored ATP for instant energy. The availability and breakdown of these ATP molecules enable muscle contractions necessary for the jump. While glycogen and glucose serve as energy sources during longer bouts of exercise or endurance activities, they must undergo metabolic processes to be converted into ATP, which takes more time than is feasible in peak power assessments. Meanwhile, oxygen is less relevant to peak power activities that demand quick, immediate energy, as these activities primarily occur anaerobically.

Thus, the significance of ATP in supplying immediate energy during brief, intense efforts, such as a vertical jump, underscores its vital role in peak power assessments.
