Abstract
Exertional Rhabdomyolysis: A Case Report of an Exceptionally Elevated Serum Creatine Kinase (CK) Level
Highlights
Rhabdomyolysis occurs as a result of skeletal muscle damage
Exertional rhabdomyolysis refers to the breakdown of skeletal muscle following a period of strenuous activity
Strenuous exercise precipitates both membrane dysfunction as well as intracellular Adenosine Triphosphate (ATP) depletion, which propagate a cascade of muscle fibre damage [7]
Summary
Rhabdomyolysis occurs as a result of skeletal muscle damage. A disruption of the integrity of muscle fibres allows release of intracellular skeletal muscle components into the extracellular space and plasma, which can have harmful effects. We present 32-year-old male with exertional rhabdomyolysis following a spin cycling class, with a peak serum CK level of 332,200 U/L. Despite a markedly elevated level of serum CK, and a correlation between serum CK and the risk of renal dysfunction being well-documented in the literature, normal renal function was noted in our case throughout.
