Aerobic and anaerobic exercise

• Anaerobic respiration


  Glucose -> energy + lactic acid
• Anaerobic exercise is exercise in the absence of enough oxygen
• Anaerobic exercise is for short high intensity exercise
• Examples of anaerobic sports/exercise


  • shotput
  • 100m sprint
• Anaerobic has the waste product lactic acid which causes fatigue in the working muscles so the muscles don't work as efficiently
• In anaerobic exercise the heart and lungs cannot supply enough oxygen to the working muscles so glucose is converted into energy without the presence of oxygen
• Aerobic exercise takes place in the presence of oxygen.
• When exercise is over a long period of time, and is steady, the heart can supply all the oxygen the working muscles need.
• Aerobic respiration is the body's preferred method of working and provides more energy than anaerobic. Less waste products
• Aerobic respiration


  Glucose + Oxygen -> Carbon dioxide + water
• In aerobic respiration water is released through sweat and carbon dioxide is released through exhaling
• EPOC (oxygen debt)


  Excess Post-exercise Oxygen Consumption
• Glucose from carbohydrates and fats supply the energy for the aerobic energy system and can supply energy for long periods of time.
• After anaerobic exercise the person breathes deeper and faster to repay oxygen debt
• The excess oxygen from EPOC is used to remove the build-up of lactic acid from muscles
