Aerobic and Anaerobic

• we get our energy from glucose
• anaerobic exercise lasts about 2-3 mins
• what is the equation for anaerobic respiration?

  glucose = energy + lactic acid
• what is the waste product in the anaerobic respiration equation?

  lactic acid
• in anaerobic respiration glucose is broken down to make energy and lactic acid
• in anaerobic exercise lactic acid is a harmful, waste product to tell our body to slow down
• in anaerobic exercise energy needs to come quickly
• what intensity is anaerobic exercise?

  high
• what is an example of anaerobic exercise?

  Weightlifting or 100m
• aerobic exercise lasts for 3 minutes or more
• in aerobic exercise you want the energy to come slowly
• what intensity is aerobic exercise performed at?

  low
• what is the equation for aerobic exercise?

  glucose + oxygen = energy + carbon dioxide + water
• carbon dioxide and water are waste products in the aerobic respiration equation
• in aerobic respiration oxygen breaks down glucose to make energy, carbon dioxide and water
• in aerobic exercise CO2 and H20 are non harmful waste products so we can carry on for a long time
• oxygen debt is found in anaerobic exercise
• the harder we exercise the more lactic acid we produce, the bigger the debt
• after anaerobic exercise there is lots of lactic acid
• after anaerobic exercise your heart rate and breathing rate remain elevated to take in more oxygen in order to break down lactic acid
• what is Epoc?

  the oxygen we take in after exercise in order to repay oxygen debt
• what are the 4 methods for exercise recovery?

  cool down, manipulation of diet, ice baths, massage
• immediately after exercise, rosie's breathing rate remains elevated. this is because whilst exercising intensely and anaerobically, her body builds up lactic acid, so her breathing rate stays elevated to let in oxygen to break down the lactic acid. it does this to repay her oxygen debt and return her body to its pre-exercise state
• ice baths: athletes immerse in ice cold water after exercise for 5-20 minutes, this causes blood vessels going to the muscles to vasoconstrict, reducing blood flow to the sore / swollen muscles. this reduces swelling and when you leave the bath your muscles vasodilate which allows lots of fresh blood and oxygen to the muscles so they can repair and recover
• ice baths and massages are used to prevent DOMS
• what does DOMS stand for ?

  Delayed Onset Muscle Soreness
• what does EPOC stand for ?

  Excess Post-Exercise Oxygen Consumption.
• EPOC (oxygen debt) is caused by anaerobic exercise producing lactic acid and requires the performer to maintain increased breathing rate after exercise to repay the debt
• manipulation of diet is used for rehydration and carbohydrates for energy
