Muscle Fibre types

Which muscle fibre type is known as 'fast oxidative glycolytic'?

• Type 1
• Type 2a
• Type 2b
• Type 1b

Which muscle fibres have the highest resistance to fatigue?

• Type 1
• Type 2a
• Type 2b

Which sporting example relates best to type 2a muscle fibres?

• 100m
• Shotput 
• 400m
• Marathon

A structural characteristic of type 2b muscle fibres is...

• high levels of mitochondria

• large motor neurone

• red in colour

• low levels of phosphocratine

A functional characteristic of type 2b muscle fibres is...

• slow speed of contraction
• high resistance to fatigue
• strong force of contraction
• poor capillary supply

A games player would use type 1 muscle fibres when...

• rebounding 
• shooting 
• re-positioning whilst ball is out of play
• pressing an opponent with the ball

Type 2b muscle fibres would be predominately used in which of these examples?

• 800m
• 10000m
• 4x400m relay
• 200m

Which of these is a functional characteristic?

• size of fibre
• resistance to fatigue
• number of capillaries
• number of mitochondria

Which muscle fibre type has the largest stores of PC?

Which two functional characteristics are correct of type 1 muscle fibres?

• Low PC stores

• Slow speed of contraction

• High number of mitochondria

• High resistance to fatigue
