Aerobic and Anaerobic Respiration

• The anaerobic respiratory system during exercise:

  The anaerobic respiratory system supplies energy very quickly for sports like vaulting in gymnastics or throwing a javelin, where the activity only lasts a few seconds.

  This system breaks down glucose into lactic acid. Produces energy very quickly.

  • Glucose -> energy + lactic acid
• EPOC (Oxygen Debt):

  • Excess
  • Post-exercise
  • Oxygen
  • Consumption

  After exercise, a person continues to breathe more deeply and rapidly than when at rest to repay oxygen debt. Used to break down lactic acid, Reduce body temperature, Remove excess CO2 from the body.

  • Cool down is the best way to recover. Should be followed by dehydration and refuelling. Should contain foods which are rich in carbohydrates and protein.
  • Athletes also use ice baths to improve recovery. Cold conditions push blood flow to deep tissue, preventing swelling and pain. Also helps to flush out lactic acid.
• The aerobic respiratory system during exercise:

  The aerobic respiratory system is responsible for producing the majority of our energy while our bodies are at rest or taking part in low-intensity exercise for long periods of time.

  • Glucose + oxygen -> energy + water + carbon dioxide.

  Glucose from carbohydrates and fats supply energy for aerobic exercise. Carbohydrate food sources include rice, bread, potatoes, bananas, and energy drinks.
