The process in which a satellite cell becomes capable of differentiating autonomously into a myoblast regardless of its environment; upon determination, the cell fate cannot be reversed. This occurs as part of skeletal muscle regeneration. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers.
