What are muscle cramps characterized by?

Muscle cramps are characterized by painful involuntary skeletal contractions. These cramps occur when a muscle involuntarily contracts and does not relax, leading to intense pain and discomfort. This condition can happen during physical activity or even at rest and is often caused by factors such as dehydration, electrolyte imbalances, or excessive muscle fatigue.

The presence of involuntary muscle contractions is key in identifying muscle cramps, as they are not under the conscious control of the individual, distinguishing them from voluntary muscle contractions that occur in response to purposeful movements. Understanding this aspect helps in effectively managing and preventing muscle cramps through proper hydration, nutrition, and conditioning practices.
