Two Cases of CrossFit®-Induced Rhabdomyolysis: A Rising Concern
Background: The author reports the cases of two adult males who presented with severe rhabdomyolysis following identical CrossFit® workouts performed on the same day, at the same time and at the same location. Results: For both cases, symptoms of rhabdomyolysis disappeared upon discontinuation of the regime and within three days of aggressive hydration and rest. Patients made a complete recovery upon discharge. Conclusion: The rhabdomyolysis was attributed to the same excruciating workout both men underwent. Exertion rhabdomyolysis exemplified by the cases presented highlights a rising concern over the health consequences of the popular training program. CrossFit®-induced rhabdomyolysis is underrecognized and should be considered in patients presenting with signs and symptoms of rhabdomyolysis.
