Energy Systems

• Fuels for ATP Resynthesis (Glucose)

  • stored in muscle + liver
  • converted into glucose before being used for ATP synthesis
  • can be done aerobically and anaerobically
• Fuels for ATP Resynthesis (Fats):

  • rich in energy but required large amounts of O2 to break down
  • used in low intensity only (aerobically)
• Fuels for ATP Resynthesis (Protein):

  • used when carb and fat stores are running low
• Fuels for ATP Resynthesis (Phosphocreatine/PC):

  • a chemical stored within muscle cells
  • used within the first 10secs of intense exercise
