Anaerobic Respiration
Most normal movement involving muscles uses
energy produced by aerobic respiration. When
exercise is vigorous or explosive, the supply of
oxygen becomes insufficient even though the
heart rate and breathing rate are increasing.
There will still be a supply of glucose but the
muscle cells will now have to respire
anaerobically.…read more

Here's a taster:

Anaerobic respiration will occur when there is a
shortage of oxygen and muscle fibres are
becoming fatigued. The end products of
anaerobic respiration are lactic acid and some
water. As these substances build up in muscle
tissues they will start to ache and some extreme
cases we may suffer from cramp.…read more

Here's a taster:

The harmful biprodcuts of anaerobic
respiration are carried out of the muscles in
the blood and their removal can be aided by
massage
· However, these substances will need to be
broken down to less harmful carbon dioxide
and water. This process requires extra oxygen
which can be provided by deep breathing and
this extra amount is the oxygen debt. This is
why a person will often puff and pant long
after a race has finished…read more

Here's a taster:

Anaerobic respiration is less
efficient than aerobic
respiration. Training helps
the body deal with the
consequences of vigorous
exercise and helps the body
to recover faster…read more
