AbstractMultiple studies have reported the metabolic benefits of high-intensity exercise programs like CrossFit. If these high-intensity exercises are not done in a proper structured pattern, adverse outcomes like rhabdomyolysis can occur. Here we discuss a case of a patient who undertook one session of CrossFit exercise and developed exertional rhabdomyolysis. A 22-year-old Caucasian male presented to the emergency department with complaints of generalized body ache and passage of dark-colored urine. His symptoms began after two days of an exhaustive session of CrossFit exercise. Blood test in the emergency showed elevated creatine kinase (CK) of 132,540 units per liter (U/L), normal renal function (creatinine and blood urea nitrogen), and normal serum electrolytes. His clinical symptoms and lab findings were consistent with exertional rhabdomyolysis. He was treated with aggressive intravenous fluids and oral hydration therapy. He did not develop any complication and he was discharged on the sixth day. This case report demonstrates a possible preventable rhabdomyolysis that developed secondary to undue participation in CrossFit exercise.Copyright © 2021, Adhikari et al.
