state the reason for delayed fatigue in red muscles fibre
answer me fast it's urgent please

Answer 1

QUESTION :-

What causes muscle fatigue ??

ANSWER :-

Muscle fatigue may be due to precise molecular changes that occur in vivo with sustained exercise. It has been found that the ryanodine receptor present in skeletal muscle undergoes a conformational change during exercise, resulting in "leaky" channels that are deficient in calcium release.

Answer 2

Answer:

. The red muscle fibers are rich in blood capillaries and myoglobin. They also contain a greater number of mitochondria than the white muscle fibers. ... Thus, they can contract for a long time while the white muscle fibers get fatigued after short periods of contraction
