The Supply And Use of Fuels During Sprinting

Outline the problems associated with the supply and use of fuels during sprinting and relate this to the sprinting muscles’ reliance on non-oxygen/non-mitochondrial based ATP production

  • A large amount of energy is required for sprinting, and it must be produced in a short amount of time.
  • During sprinting, muscles are unable to receive a supply of oxygen quickly enough. They must then rely on anaerobic based systems that are able to rapidly produce ATP.
  • A high concentration of glucose, followed by the process of glycolysis, results in a much faster production of ATP than the TCA cycle or Oxidative Phosphorylation could provide.
