Type I
A
Slow twitch fibres; suited to low intensity work e.g. Marathon running as they can be used for a long period without fatiguing.
3
Q
Type IIa
A
Fast twitch muscle fibres used in anaerobic work; can be improved through endurance training to increase their resistant to fatigue
.
4
Q
Type IIx
A
Fast twitch muscle fibres used in anaerobic work and can generate much greater force than any other fibre types but fatigue quickly.
5
Q
