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.

Top

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.

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!

A widespread belief in a particular animal bone, carried in the pocket or placed under the pillow, to prevent or cure cramp has a long history, and is still found. In the earliest references, in the 16th century, it was a bone from a hare: ‘The lytle bone in the knee ioynt of the hinder legge of an hare, doth presently helpe the crampe if you touch the grieved place therewith. Often proved’ (Lupton, 1579: i. 87; quoted in Opie and Tatem) and Reginald Scot (1584: book, 13 chapter 10) agreed. By the 19th century the effective bone was usually the patella, or knuckle-bone of a sheep.

Columbia Encyclopedia: cramp

Top

cramp, painful uncontrollable contraction of a muscle or group of muscles. The type that results from cold, strain, or disturbance of circulation (as experienced by swimmers) is eased by massage and the application of heat. Cramp in the abdominal or skeletal muscles brought on by hard physical exertion in extremely high temperatures (e.g., in miners, stokers, or firemen) because of loss of salt from the body during profuse perspiration can last for hours or days if untreated. Such cramps are considered to be a type of heat exhaustion. A cool atmosphere and the replacement of salt and water orally or intravenously is required, and application of heat is not recommended. Heat cramps in persons who do heavy labor can be prevented by the addition of salt to drinking water or by taking salt tablets. Contraction of muscles in a hollow organ is known as colic. A stitch in the side is due to a cramp in the muscles between the ribs.

Cramps are unpleasant, often painful sensations caused by contraction or over-shortening of muscles. Cramps can be caused by cold, overexertion or low calcium level in blood (especially for adolescents, who need calcium for both blood and bone maturing) though the most common reason is low sodium and potassium levels in blood accompanied by excessive dehydration. Illness or poisoning can also cause cramps, particularly in the stomach, which is referred to as colic if it fits particular characteristics.

Causes

There are a number of causes of cramping:^[1] hyperflexion; hypoxia; exposure to large changes in temperature; dehydration; low blood salt; or low blood calcium. Muscle cramps may also be a symptom or complication of pregnancy, kidney disease, thyroid disease, hypokalemia or hypocalcemia (as conditions), restless legs syndrome, varicose veins,^[2] and multiple sclerosis.^[3]

Electrolyte disturbance may cause cramping and tetany of muscles, particularly hypokalaemia (a low level of potassium) and hypocalcaemia (a low level of calcium). This disturbance arises as the body loses large amounts of interstitial fluid through sweat. This interstitial fluid is composed mostly of water and table salt (sodium chloride). The loss of osmotically active particles outside muscle cells leads to a disturbance of the osmotic balance and swelling 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 and the calcium ions remain bound to the troponin and the muscle contraction is continued. This may occur when the lactic acid is high in the cells.

As early as 1965 it was observed that leg cramps and restless legs syndrome can be a result of excess insulin, sometimes called hyperinsulinemia.^[4] Hypoglycemia & reactive hypoglycemia are also known to be associated with excess insulin [or insufficient glucagon] and avoidance of low blood glucose concentration may help avoid cramps.

Iatrogenic causes

Statins are known to cause myalgia and cramps among other possible adverse reactions or side effects including substantially lowering blood glucose concentration.^[5] Additional factors increasing probability for these adverse side effects are physical exercise, age, female gender, history of cramps and hypothyroidism. Up to 80% of athletes using statins suffer significant muscular adverse effects including cramps;^[6] the rate appears to be approximately 10-25% in typical population using statins.^[7]^[8] In some cases these adverse effects will disappear after switching to a different statin, however they should not be ignored if they persist as they can, in rare cases, develop into a more serious problem. Coenzyme Q10 supplementation can be helpful to avoid some statin related adverse effects but currently there is not enough evidence to prove effectiveness in avoiding myopathy or myalgia.^[9]

Treatment

Muscle cramps can be treated by applying a soft massage on the cramped muscle, stretching your hands up above you and breathing in deeply through the mouth, stretching the muscle and applying heat or cold. Heat improves superficial blood circulation and makes muscles more flexible, so some people find heat to be soothing for muscle cramps. Application of excessive heat or cold to sore muscles may bring on cramps. Pounding on a cramped muscle can increase soreness. Trying to put weight on a cramp too soon can cause another cramp, or even a temporary loss of ability to use that muscle. For leg cramps the quickest treatment involves bending over and grabbing the end of the toes, fully straightening out the leg; the cramp will eventually dissipate.

In the case of inadequate oxygenation, excess lactic acid, produced by anaerobic respiration, builds up and stresses the muscle. In addition to the methods described above, cramps from poor oxygenation can be improved by rapid deep breathing.

Cramps from lack of water and/or salt can be treated by drinking water and/or increasing salt intake, respectively.

There is no scientific evidence to support the widely held claim by the sports nutrition industry that intake of specially composed electrolyte drinks has any advantage over intake of plain table salt (via drink or food) and water to counter these electrolyte disturbances and muscle cramps in people with a well-functioning renal system.

Eating foods high in potassium can help prevent muscle cramps.^[10]

In the case of cramps caused by varicose veins, treatment of the affected veins with sclerotherapy, endovenous laser or surgery usually provides relief.

Quinine has been prescribed for the treatment of leg cramps. However, because of the drug's risks, the United States Food and Drug Administration has declared it should not be used to prevent or treat leg cramps.^[11]

Crampex is the only licensed medicine available without prescription for both the treatment and prevention of muscle cramp at night.

Specific types of cramps

Smooth muscle cramps

Smooth muscle contractions lie at the heart of the cramping (or colicky) pain of internal organs. These include the intestine, uterus, ureter (in kidney stone pain), and various others.

Menstrual cramps

Main article: Dysmenorrhea

Menstruation is also highly likely to cause cramps of varying severity in the abdomen that may radiate to the lower back and thighs. Menstrual cramps can be treated with ibuprofen, acetaminophen (paracetamol), stretching exercises, or the application of heat through such means as warm baths or heating pads. Menstrual cramps that do not respond to self-treatment can be a symptom of endometriosis or other health problems.

Skeletal muscle cramps

Skeletal muscles are muscles that can be voluntarily controlled. Of the skeletal muscles, those which cramp the most often are the calves, thighs, and arches of the foot. These cramps are seemingly associated with strenuous activity and can be intensely painful.

Nocturnal leg cramps

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. Only a few fibers of a muscle may be activated.^[12] The duration of nocturnal leg cramps is highly variable with cramps sometimes only lasting a few seconds and other times several minutes. Soreness in the muscles may remain for some time after the cramp ends. These cramps are more common in older people but may happen to anyone. They can happen quite frequently in teenagers and in some people while they are exercising at night. Nocturnal leg cramps can be very painful, especially if the person is dehydrated. Usually, putting some pressure on the affected leg by walking some distance will make the cramp go away.^[13]

The precise cause of these cramps is unclear. Potential contributing factors are believed to include dehydration, low levels of certain minerals (magnesium, potassium, calcium, and sodium), and the reduced blood flow through the muscles attendant in prolonged sitting or lying down. Less common causes include more serious conditions or the use of drugs.

Nocturnal leg cramps may be relieved by stretching the affected leg straight out and pointing the toes upward. Quickly standing up and walking a few steps may also shorten the duration of a cramp.^[13]

Nocturnal leg cramps (almost exclusively calf cramps) are considered to be 'normal' during the late stages of pregnancy. They can, however, vary in intensity from mild to incredibly painful.
