Question

Why red muscle fibres have less glycogen?

Answer 1

In contrast to thered fibers, they gain their energy anaerobically, which means without oxygen and mainly from the sugar glycogen. Glycogencan provide energy very quickly and in the short term, so the white fibers are able to contract faster and stronger.

Answer 2

Answer:

serves of glycogen and high-energy phosphate are de - pleted (33). Histochemical evidence also indicates that red muscle fibers have lower phosphorylase.
