Types And Characteristics Of Muscle Fibres Flashcards
What are the three types of muscle fibres
1 slow oxidative (SO)
- Fast oxidative glycolytic (FOG)
- Fast glycolytic (FG)
What are slow oxidative fibres
The endurance fibres
What are fast oxidative glycolytic fibres
Speed endurance fibres
What are fast glycolytic fibres
Speed/power fibres
Talk about the size of the three fibres
SO = small FOG = intermediate FG = large
Talk about the neurone size for the three fibres
SO = small FOG = intermediate FG = large
Talk about the amount of capillaries for the three fibres
SO = many FOG = many FG = few
Talk about the myoglobin of the three fibres
SO = high FOG = high FG = low
Talk about mitochondria content for the three fibres
SO = many FOG = many FG = few
Talk about the glycogen stores for the three fibres
SO = low FOG = intermediate FG = high
Talk about the phosphocreatine (pc) stores for the three fibres
SO = low FOG = intermediate FG = high
Talk about the speed of contraction for the three fibres
SO = slow FOG = fast FG = fast
Talk about the force of contraction for the three fibres
SO = low FOG = high FG = high
Talk about the rate of fatigue for the three fibres
SO = slow FOG = intermediate FG = fast
What are the predominant ATP pathways for the three fibres
SO = aerobic FOG = aerobic and anaerobic FG = anaerobic
