A tennis player is in a rally lasting 45 seconds at moderate-high intensity. Which energy system sequence best represents their energy production?

  1. Glycolytic → ATP-PCr → Aerobic
  2. Aerobic → ATP-PCr → Glycolytic
  3. ATP-PCr → Aerobic → Glycolytic
  4. ATP-PCr → Glycolytic → Aerobic

\(D\)

Show Worked Solution

Consider Option D:  ATP-PCr → Glycolytic → Aerobic

  • Shows the natural progression of energy systems as intensity/duration increases

Other Options:

  • A is incorrect: ATP-PCr is the initial energy system
  • B is incorrect: ATP-PCr is the initial energy system and aerobic takes longer to become predominant
  • C is incorrect: Glycolytic precedes Aerobic for moderate-high intensity

\(\Rightarrow D\)
