Biological process

positive regulation of skeletal muscle fibre development, positive regulation of skeletal myofiber development, positive regulation of skeletal myofibre development, up regulation of skeletal muscle fiber development, up-regulation of skeletal muscle fiber development, upregulation of skeletal muscle fiber development

Any process that activates, maintains or increases the rate of skeletal muscle fiber development. Muscle fibers are formed by the maturation of myotubes. They can be classed as slow, intermediate/fast or fast.
