IT can happen for no reason, it seems, taking you completely by surprise. And it can be excruciating. Suddenly, a muscle contracts violently, as if it had been prodded with a jolt of electricity. And it remains balled in a tight knot as painful second after painful second drags on.
A seized calf muscle or a hamstring can be frightening. Swimmers fear they will drown. Cyclists nearly fall off their bikes. Runners drop to the ground, grimacing, gritting their teeth.
The contraction is so strong that you could not will yourself to ball your muscle that tightly. And your muscle is likely to feel sore the next day.
You have had a cramp, an experience so common among endurance athletes, researchers say, that almost everyone who has tried endurance sports has had a muscle cramp or has a friend who has had one.

Cramps afflict 39 percent of marathon runners, 79 percent of triathletes, and 60 percent of cyclists at one time or another, said Dr. Martin P. Schwellnus, a professor of sports medicine at the University of Cape Town.
Cramps can occur during exercise, immediately after, or he said, as long as six hours later.
Yet common as they are and terrible as they can be, no one really understands cramps. They are a medical mystery.
“I would say, bottom line, there is no really convincing biological explanation for muscle cramps,” said Dr. Andrew Marks, a muscle researcher and chairman of the department of physiology and cellular biophysics at Columbia University College of Physicians and Surgeons.
Medical textbooks skirt the topic, he added, often avoiding any explanation. And few scientists have studied cramps.
But as anyone who has ever complained of cramps will attest, lots of advice is circulating on how to avoid them and lots of people — friends, coaches, doctors — think they have a solution.
