Question

Difference between red and white muscle fibres

Goldy C · Accepted Answer

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
