The Effects of Exercise on the Body

B2 4.2 
Energy from Respiration
The Effect of exercise on the body 

  • Muscles tissue is made up of protein fibres. These contract when they are supplied with energy from respiration.They contain mitochondria to carry out aerobic respiration and supply needed supply the energy needed.
  • Muscles fibres usually occur in lagre groups known as muscles. The contraction of one muscle allows another to relax.
  • Your muscles also glucose as the carbohydrates glycogen. Glycogen can be cobverted rapidly back to glucose to use during exercise. The glucose is used in aerobic respiration to provide the enrgy to make muscles contract.

 Glucose + Oxygen  -->  carbon dioxide + water (+ energy)

The Response to Exercise

  • As a result of exercise muscles contract harder and faster meaning more glucoseand oxygen is supplied. Muscles also produce large amounts of carbon dioxide.
  • Your heart rate increases and the arteries supplying blood to your dilate
  • Your breathing rate increases and you breathe more deeply to bring more oxygen to the lungs to be carried through the bloodstream to the muscles.

The Benefits of Exercise

Both the heart and lungs become larger develpoing a more efficent blood supply meaning the body can function as effectivly as possible.
