Difference between red and white muscle fibres

The main difference between the red and white muscle fibres are;
Red Muscle Fibres :
  • The red muscle fibres are active during the low intensity and long duration.
  • They are usually active throughout all the muscular contractions.
  • They are known as the slow-twitch muscle.
  • The presence of large amount of myoglobin makes them red in colour.
  • They are thin muscles fibres.
White Muscle Fibres :
  • The white muscle fibre becomes active at high intensity action short duration.
  • They are known as the fast-twitch muscle.
  • They are active during fast contraction.
  • Due to less amount of myoglobin they appears white in colour.
  • They are thick muscle fibres.
