A Case of Rhabdomyolysis Caused by Blood Flow-Restricted Resistance Training.

Blood flow-restricted resistance (BFRR) training is effective as a means to improve muscle strength and size while enduring less mechanical stress. It is generally safe but can have adverse effects. We present a case of an active duty Soldier who developed rhabdomyolysis as a result of a single course of BFRR training. He was presented to the emergency department with bilateral lower extremity pain, was admitted for electrolyte monitoring and rehydration, and had an uncomplicated hospital course and full recovery. This is an increasingly common mode of rehabilitation in the military, and practitioners and providers should be aware of it and its possible adverse effects.
