There is a very low risk of Rhabdomyolysis. Rhabdomyolysis does not occur when individuals follow the safety rules of the B Strong BFR Training System. A constellation of factors must occur together to get rhabdomyolysis. Rhabdomyolysis is associated with a variety of factors including; the first time of a new exercise, exercising when dehydrated, eccentric exercise, exercise with an occluded circulation, exercise with heavy weights, exercise of long duration. There is a comprehensive list below. It takes a “perfect storm” of many of these factors coming together to get wide spread muscle fiber damage that can lead to rhabdomyolysis. If one follows the B Strong BFR Training System safety rules, one can not get all these factors coming together at the same time.
Rhabdomyolysis is defined as major destruction of muscle fibers. As muscle fibers are torn and damaged, the intracellular contents are released into the circulation and the kidney attempts to clear them from the circulation. If the load of cellular debris is too great for the kidneys, renal failure ensues. If not treated, death follows. There are many causes of rhabdomyolysis. The most common causes include:
- The use of alcohol or illegal drugs such as heroin, cocaine or amphetamines
- Extreme muscle strain (especially in someone who is an untrained athlete; it can happen in elite athletes and can be more dangerous if there is more muscle mass to break down)
- A crush injury such as from an auto accident, fall, or building collapse
- Long-lasting muscle compression such as caused by prolonged immobilization after a fall or lying unconscious on a hard surface during illness or while under the influence of alcohol or medication
- The use of medications such as antipsychotics or statins, especially when given in high doses
- Electrical shock injury, lightning strike, or third-degree burn
- A very high body temperature (hyperthermia) or heat stroke
- A metabolic disorder such as ketoacidosis
- Diseases of the muscles (myopathy) such as congenital muscle enzyme deficiency or Duchenne’s muscular dystrophy
- Viral infections such as the flu, HIV, or herpes simplex virus
- Bacterial infections leading to toxins in tissues or the bloodstream (sepsis)
