Anaerobic Systems

Because there is no requirement for oxygen in these systems (ATP-PC and
Lactic Acid [1]) all the changes that take place occur at the tissue level,
as a result of exercise performed at maximal (or near maximal) intensities.

* we see an increase in muscle size (hypertrophy), but not number

* strength training requires high intensity loads and low repetitions [2]
to ensure that fast twitch fibres are recruited

* lower loads and increased numbers of repetitions recruits slow twitch
fibres

* we see a greater change in males compared with females, as males have
more testosterone

* this is not to say females can't increase strength levels - they can,
but do not "bulk up" to the same extent

* these stores increase; however, there is a limit of approximately 12
seconds' worth of ATP-PC stores that can be stored by the muscles

* it makes sense that if we train at high intensities the body is going
to get faster at splitting ATP-PC so that it can generate higher levels of
energy

* sprint training [3] increases the level of the enzyme responsible for
this

* the result is a greater level of energy release and restoration
