muscles
In this section you will need to know about the following topics;
Structure and function
Characteristics of different fibre types (slow twitch (type I), fast glycolytic (type IIb) and fast oxidative glycolytic (type IIa)) and examples in
sport
Sliding filament hypothesis
Motor units; spatial summation.

fibre types
Questions here will ask you to identify a particular fibre type for a given activity. In the past it has been an activity that lends its self to either fast twitch or slow twitch fibres. However, you do still need to learn about FOG fibres. Make sure you learn the characteristics of each fibre type .

sliding filament theory
Questions here requires you to describe how muscles contract according to the theory, or the role of particular components of the theory. Make sure you read the question and think about what its actually asking you to explain!

motor units
Questions here require you to understand; What is a motor unit, how we can vary the strength of contactions in our muscles and explain the All or None Law.
