A sudden, uncoordinated, prolonged spasm in a muscle, causing it to become taut and excruciatingly painful. Cramps commonly occur in the calf, thigh, and hip muscles after strenuous exercise. As yet, there is no complete explanation for their development. Several causes have been suggested including muscle damage, dehydration, low blood glucose levels, and restriction of the blood supply to the muscles. Exercisers are more likely to suffer cramps if they are out of condition, wear low-heel shoes, or do not take enough fluids and electrolytes during exercise (see also heat cramps). Cramps are often relieved by gentle static stretching, gentle massage, and rest. To reduce the risk of cramps:
• warm up properly; include static stretching
• increase exercise intensity gradually during a workout
• take it easy when performing a new type of workout
• drink plenty of fluids before and after exercise.
Muscle cramps are one of the most common clinical problems suffered by athletes in endurance events. A third to a half of marathon runners and two-thirds of triathletes have been reported to experience exercise-associated muscle cramping (EAMC) at some time in their lives. Other forms of cramp affecting healthy people include nocturnal foot and calf muscle cramps, those arising from certain occupations (such as hand cramps in pianists and typists) and those associated with pregnancy. Cramps can also occur in a variety of relatively rare medical conditions, congenital or acquired, including metabolic or neuromuscular disorders, poisonings, and drug effects. This article will focus principally on EAMC — a spasmodic, painful involuntary contraction of skeletal muscle that occurs during or immediately after muscular exercise — since it is the most studied of the common forms, and has recently become better (though still not completely) understood.
The interest in skeletal muscle cramping associated with exercise was first stimulated at the turn of the century by reports that it occurred during physical work in hot, humid environments, including steam ships and mines. In these early studies the proposed explanation was a disturbance of body fluid and salt balance. The early observations led to the ‘serum electrolyte depletion’ and ‘dehydration’ theories for the cause of the cramps. Such theories are consonant with the fact that widespread cramping is one of the symptoms of severe hyponatraemia (salt deficiency). Thus they are still accepted by some clinicians and applied in practice by many athletes who believe adequate salt and water intake to be important cramp-preventatives.
Recent evidence, however, challenges the salt-and-water view. More than one careful study has shown that most runners with acute EAMC are not salt-deficient, dehydrated, or overheated. Also, cramp among sports people can occur in cold conditions (such as cold water, for swimmers). Factors actually associated with EAMC have been identified using three research approaches: epidemiological investigations; studies on spinal reflex activity during muscle fatigue in animals; and recording of muscle electrical activity (electromyography, EMG) in human volunteers during EAMC. The latter technique demonstrates intense electrical activity, at exceptional frequencies (up to 300 Hz), in both EAMC and occupationally cramped muscles, and indeed in the cramps associated with a number of medical conditions, though not quite all. Critical analysis of these factors has led to the development, by Scwellnus and colleagues, of a novel hypothesis for the cause of EAMC.
It seems that most forms of exercise-associated cramp result from an abnormally sustained activity of the nerve cells in the spinal cord which control skeletal muscle, the alpha motor neurons. Fatigue appears to be the central factor in EAMC. Fatigue enhances the input to the alpha motor neurons from the main receptors in the muscles (muscle spindles) and inhibits the input from the receptors in their tendons (Golgi tendon organs) that signal tension. As the spindle signals excite alpha motor neurons, while those from tendon organs are inhibitory, these fatigue effects can combine to promote uncontrolled activity in the relevant regions of the spinal cord. It is a common experience that cramp may be precipitated by contraction of the muscle from an already shortened position, and this of course is when the tension signal from its tendon is weakest.
In a recent epidemiological study of over 1300 marathon runners, risk factors for EAMC were identified. Cramps were more likely with older age, a longer history of running, a higher body mass index, shorter daily stretching time or irregular stretching habits, and if there was a family history of cramping.
In addition, runners themselves identified specific conditions that were associated with EAMC: high-intensity running (racing), long duration of running (most cramps occur after 30 km in a standard marathon), hill running, subjective muscle fatigue, and poor performance in the race.
The two most important observations from these data are that cramp is associated with running conditions that can lead to premature muscle fatigue, and that poor stretching habits appear to increase the risk.
The muscles most prone to cramping are those that span two joints (for example, the gastrocnemius spanning knee and ankle). These muscles are typically activated when shortened — as in swimming, when the gastrocnemius contracts while the toes are already pointed. In runners, the situation is less clear-cut, but activation is common when only one of the two joints is extended. As the foot strikes the ground, the toes are pointed — the ankle is extended by contraction of the gastrocnemius — whilst the knee is also extended. Then in the load-bearing phase of the stride the foot has flexed, which would stretch the gastrocnemius — but now the knee is bent. The gastrocnemius is then activated again in this relatively shortened position. Such contractions are presumed to produce significantly less tension in the tendons than contractions starting near full extension, resulting in less inhibiting effect on motor neuron activity of the sort described above.
In localized cramp, confined to one or 2 muscle groups, the typical scenario is as follows: there is distressing pain in the muscle that develops gradually over a few minutes during intense or prolonged exercise. The muscle is contracted and hard, and an observer can see fasciculation — small twitchings — over its surface. The onset of the cramp is usually preceded by muscle fatigue and more immediately by a feeling of twitching in the muscle (‘cramp prone state’). This is followed by spasmodic spontaneous contractions and frank cramping if the activity is continued. Relief from the ‘cramp prone state’ occurs if the activity ceases or, temporarily, if the muscle is passively stretched. Once activity stops, there may be alternating periods of cramping and relief.
The athlete who has generalized severe cramping, extending to non-exercising muscle groups, or who is also confused or comatose, presents an emergency. This condition is not typical EAMC as a result of fatigued muscle, but a whole body, usually metabolic, disturbance requiring immediate hospitalization and full investigation.
The immediate treatment for acute EAMC occurring in a sports event, or for cramp experienced in bed, should consist of passive stretching of the affected muscle groups, holding the muscle in stretched position until return to normal muscle length does not lead to recurrence of cramp. General supportive treatment includes maintaining a comfortable temperature and providing fluids if required.
The key to the prevention of acute EAMC is to protect the muscle from developing premature fatigue during exercise. The following advice to athletes is recommended: be well conditioned for the activity; perform regular stretching exercises for the muscle groups that are prone to cramping; and have adequate nutritional intake (carbohydrate and fluid) to prevent premature muscle fatigue during exercise. However, athletes who continue to be prone to EAMC must face the need to perform their activity at a lower intensity or a shorter duration.

Numerous cures for cramp have been recorded, some with an alleged physical basis, while others are purely magical. Forbes gives several examples of verbal charms, including the following from a schoolboy Samuel Coleridge Taylor:
The devil is tying a knot in my leg
Mark, Luke, and John, unloose it I beg
Crosses three we make to ease us
Two for the thieves, and one for Christ Jesus!

As yet, there is no complete explanation for their development. Suggested causes include muscle damage, dehydration, low blood-glucose levels, and restriction of blood supply causing ischaemia. Risk of cramps during exercise is increased by poor condition, wearing low-heel shoes, and not taking sufficient fluid or electrolytes. Cramps are relieved by gentle, static stretching, massage, and rest. See also caecal slap syndrome, heat cramps, rigor complex.

Cramps are unpleasant, often painful sensations caused by muscle contraction or over shortening. Common causes of skeletal muscle cramps include muscle fatigue, low sodium, and low potassium. Smooth muscle cramps may be due to menstruation or gastroenteritis.

Causes of cramping include[1] hyperflexion, hypoxia, exposure to large changes in temperature, dehydration, or low blood salt. Muscle cramps may also be a symptom or complication of pregnancy, kidney disease, thyroid disease, hypokalemia, hypomagnesemia or hypocalcemia (as conditions), restless-leg syndrome, varicose veins,[2] and multiple sclerosis.[3]
Electrolyte disturbance may cause cramping and muscle tetany, particularly hypokalaemia and hypocalcaemia. This disturbance arises as the body loses large amounts of interstitial fluid through sweat. This interstitial fluid comprises mostly water and table salt (sodium chloride). The loss of osmotically active particles outside of muscle cells leads to a disturbance of the osmotic balance and therefore shrinking of muscle cells, as these contain more osmotically active particles. This causes the calcium pump between the muscle lumen and sarcoplasmic reticulum to short circuit; the calcium ions remain bound to the troponin, continuing muscle contraction.
As early as 1965, researchers observed that leg cramps and restless-leg syndrome result from excess insulin, sometimes called hyperinsulinemia.[4] Hypoglycemia and reactive hypoglycemia are associated with excess insulin (or insufficient glucagon), and avoidance of low blood glucose concentration may help to avoid cramps.
Smooth muscle contractions lie at treatment[clarification needed] may be symptomatic of endometriosis or other health problems. Menstrual cramps may also occur before a female menstrual cycle.
Skeletal muscles can be voluntarily controlled. Skeletal muscles that cramp the most often are the calves, thighs, and arches of the foot. A so-called Charley horse, this kind of cramp is associated with strenuous activity and can be intensely painful—though skeletal cramps can occur while relaxing. Around 40% of people who experience skeletal cramps are likely to endure extreme muscle pain, and may be unable to use the affected limb. It may take up to seven days for the muscle to return to a pain-free state.
Nocturnal leg cramps are involuntary muscle contractions that occur in the calves, soles of the feet, or other muscles in the body during the night or (less commonly) while resting. The duration of nocturnal leg cramps is variable with cramps lasting anywhere from a few seconds to several minutes. Muscle soreness may remain after the cramp itself ends. These cramps are more common in older people.[5] They happen quite frequently in teenagers and in some people while exercising at night. The precise cause of these cramps is unclear. Potential contributing factors include dehydration, low levels of certain minerals (magnesium, potassium, calcium, and sodium), and reduced blood flow through muscles attendant in prolonged sitting or lying down. Nocturnal leg cramps (almost exclusively calf cramps) are considered 'normal' during the late stages of pregnancy.[citation needed] They can, however, vary in intensity from mild to extremely painful.
Various medications may cause nocturnal leg cramps:[6]
Besides being painful, a nocturnal leg cramp can cause much distress and anxiety.[7]
Usually, putting some pressure on the affected leg by walking some distance will end the cramp.[8]
Statins cause myalgia and cramps among other possible side effects. Additional factors, which increase the probability for these side effects, are physical exercise, age, female gender, history of cramps, and hypothyroidism. Up to 80% of athletes using statins suffer significant adverse muscular effects, including cramps;[9] the rate appears to be approximately 10–25% in a typical statin-using population.[10][11] In some cases, adverse effects disappear after switching to a different statin; however, they should not be ignored if they persist, as they can, in rare cases, develop into more serious problems. Coenzyme Q10 supplementation can be helpful to avoid some statin-related adverse effects, but currently there is not enough evidence to prove the effectiveness in avoiding myopathy or myalgia.[12]
Skeletal muscles work as antagonistic pairs. Contracting one skeletal muscle requires the relaxation of the opposing muscle in the pair. Cramps can occur when muscles are unable to relax properly due to myosin fibers not fully detaching from actin filaments. In skeletal muscle, ATP must attach to the myosin heads for them to disassociate from the actin and allow relaxation — the absence of ATP in sufficient quantities means that the myosin heads remains attached to actin. An attempt to force a muscle cramped in this way to extend (by contracting the opposing muscle) can tear muscle tissue and worsen the pain. The muscle must be allowed to recover (resynthesize ATP), before the myosin fibres can detach and allow the muscle to relax.
Stretching may be helpful in treating simple muscle cramps [13]. With exertional heat cramps due to electrolyte abnormalities (primarily sodium loss and not calcium, magnesium, and potassium ) appropriate fluids and sufficient salt improves symptoms.[14]
Quinine is likely to be effective. However, due to side effects its use should only be considered if other treatments have failed and in light of these concerns.[15] Vitamin B complex, naftidrofuryl, lidocaine, and calcium channel blockers may be effective for muscle cramps.[15]
Adequate conditioning, stretching, mental preparation, and adequate fluid/electrolyte balance are likely helpful in preventing muscle cramps. [16].
