Muscle soreness and rhabdomyolysis

Abstract

The soreness that commonly follows unaccustomed and strenuous exercise is unlikely to be due to inflammation of the muscles. However, the rarer and more serious exercise-induced rhabdomyolysis appears to have a different pathogenesis, with clinical signs including tissue inflammation and muscle cell death, as well as elevated creatine kinase and myoglobinuria. Soreness and rhabdomyolysis can both be caused by the same type of muscular activity.
