  • to be able to exercise the muscles of the body requires energy
  • this is supplied by respiration

glucose + oxygen ---> releases large amount of energy + carbon dioxide + water.

  • the more exercise being done, the more oxygen and glucose the cells will need.
  • therefore a number of changes take place-

1) heart rate increases

2) rate and depth of breathing increases

3) arteries suppling muscles dilate

- these changes increase blood flow - therefore increasing supply of glucose and oxygen.

- also increases the rate of removal of carbon dioxide.

2 of 3

glycogen stores

  • muscles contain glycogen stores, is this a form of carbohydrate - which can be rapidly converted to glucose and is used during exercise.
