What Causes Muscle Cramps?

Many endurance athletes and daily exercisers alike suffer the pain of muscle cramps, usually in the calves, either during a sporting event or workout session or directly after. What causes these painful cramps?

What Causes Muscle Cramps?

There are many possible causes for why the cramping occurs. Some of these include dehydration, low blood sugar, salt imbalance due to sweating, nerve damage, compromised blood flow, heat or cold and even a disruption of energy along acupuncture meridians. And while many of these are causes for cramps in general, there is disagreement whether they are actually involved in exercise-induced cramping.

Research conducted by South African doctors on triathletes, and reported in Medicine & Science in Sports & Exercise, July 2005, found that none of the these conditions seemed to actually cause the cramping. Rather, by conducting EMG studies on the athletes, the researchers demonstrated that the most likely cause of the cramping was muscle fatigue or a tear in the affected muscle itself.

The EMG studies showed noticeably higher electrical activity in the nerves that controlled the cramped muscles. They concluded that the muscle cramps appeared to be caused by exercise-induced damage to the muscles themselves. If that’s the case, muscle cramping can be prevented by slowing down when you feel tightness or soreness in any particular muscle.

Regular chiropractic care, along with pre-exercise stretching of the muscles are probably the two best ways to avoid muscle cramping. Should you start to feel a cramp or tightening, grabbing your toes and stretching the calf may stop the cramp, but most often, the muscle needs to simply rest for a bit.

Do nerves actually get pinched?
Chiropractors recognize two types of nerve disorders involved in subluxation. The least common is a pinched nerve that diminishes nerve supply to an affected organ or tissue. More common is the irritated nerve (facilitative lesion) which overexcites nerve communications to an affected organ or tissue. Chiropractic care has been shown to help with both types.
What's a side effect?
It may sound like a bonus; something extra, but chiropractors know it should more accurately called an "unintended effect," and "unwanted effect" or in some cases an "adverse effect." A pill can't come close to matching your body's ability to create and deliver the essential compounds it needs. That's when it's important to make sure your nervous system is working correctly—the purpose of chiropractic care!
