− The release of energy from glucose without using oxygen.
− Glucose à lactic acid + energy
Advantages:
· Useful for when oxygen cannot be delivered fast enough
Disadvantages:
· Releases less energy than aerobic respiration
· Lactic acid is not removed from the body and must be broken down after exercise
EPOC:
· Anyone who exercises hard will find their breathing and heart rate take a while to return to normal when exercise has ended
· This is known as excess post-exercise oxygen consumption
