The Biochemistry of Movement > 9.7.10. Sprinting involves muscle contracting powerfully and rapidly and utilizes type 2 muscle cells > 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.
