Muscle fibre types

• SO is short for slow oxidative
• FOG is short for fast oxidative glycolytic
• FG is short for fast glycolytic
• SO has slow contraction speed
• SO has high fatigue resistance
• SO is good for aerobic exercise
• SO has a high capillary density
• SO has small neurons
• SO has both high mitochondria and myoglobin density
• FOG has large sized neurons
• FOG has fast contraction speeds
• FOG is good for both aerobic and anaerobic exercise
• FOG has moderate mitochondria and myoglobin density
• FOG has a high force of contraction
• FOG has lots of fibres per neuron
