A cramp is the tightening of a muscle into the contracted state. Muscles have two states: relaxed and contracted. A muscle is relaxed when all of the fibers within the muscle are elongated. When the muscle does its job, calcium goes into the muscle cells and sodium rushes out. Doing so causes the fibers to shorten and the muscle to pull--doing itâs work.
