Type IIB fibers are geared to generate ATP by anaerobic metabolic processes, however, they are not able to supply
skeletal muscle fibres continuously with sufficient ATP, and fatigue easily.

skeletal muscle fibres

Abstract Type 1 ryanodine receptor (RyR1) is preferentially expressed in
skeletal muscle, and mutations in the gene have been associated with malignant hyperthermia, a pharmacogenetic disease, and with several congenital myopathies, including central core disease, multiminicore disease, centronuclear myopathy, congenital
fibre type disproportion.
Failure of satellite cell activation is also believed to cause
skeletal muscle loss as these cells fuse with the
muscle fibres and maintain their normal functioning.
Skeletal muscle has different types of
muscle fibres with distinct variants of ATP - dependent motor proteins or Myosins.
