Extreme physical activity such as weight lifting is just one potential cause of rhabdomyolysis which is the rapid breakdown of muscle tissue. The breakdown of skeletal muscle leads to a large amount of muscle proteins in the blood which can be harmful to the kidneys and result in acute renal failure. Sometimes dialysis is required to treat the kidney failure.

Risk Factors

There are several risk factors associated with exertional rhabdomyolysis. Most cases will occur in military, police or fire recruits who are going through the intense physical training demanded by the profession. Individuals who have previously been fairly sedentary and initiate a demanding weight lifting regimen will be at increased risk of developing rhabdomyolysis. The intensity of the weight lifting or exercise plays a greater role in muscle damage than the duration. Also negative repetitions will cause greater muscle damage than positive repetitions. This is because most weight lifters will use a greater weight with negative reps than could otherwise be lifted. This in effect increases the intensity of the workout. Dehydration during and after the exercise session also puts an individual at risk for developing the disorder. Exercising during warm weather or conditions will also lead to a dehydrated state.

Prevention

Knowing the risk factors of rhabdomyolysis enables one to develop strategies for the prevention of rhabdomyolysis following weight lifting or other exercises. One should never go into an exercise session in a dehydrated state. Adequate fluid intake of an electrolyte containing sports drink during the weight lifting session should be assured. Consumption of a protein recovery drink is also beneficial for preventing the development of rhabdomyolysis. Of course, one should be in a relative state of physical condition prior to engaging in intense exercise and not overdo it. Avoiding negative repetitions of a greater amount of weight than could reasonably be lifted is also a good idea in order to prevent muscle injury.

Knowing the risk factors and how to prevent rhabdomyolysis can make for a healthier and safer weight lifting session.
