By muscle cramps we mean real spasms of the striated muscles. In fact, in addition to the muscle cells (partially involved), motor neurons are also responsible for the cramps.
These are involuntary contractions typified by violence and sudden appearance.
In other words, (muscle) cramps cause the involuntary contraction of the muscles, which instead "should" depend on the will.
The etiology of cramps is multifactorial, even if their appearance does not necessarily require the coexistence of all potentially responsible factors; the most relevant are:
- Malnutrition.
- Alcoholism.
- Intense and / or prolonged physical activity carried out in hot humid environments.
- Increased diuresis.
- Pathologies.
- Insufficient fitness for physical performance.
- Very low temperatures.
- Taking medications.
- Accumulation of lactic acid and other catabolites: the role of its concentration is not yet known.
We must not forget that the appearance of cramps is correlated to the "increased risk of injury. In reality it is an indirect statistical link that depends above all on the poor level of general training and other risk factors typical of neophytes. D" on the other hand , on some occasions the pain generated by cramps can in itself remain for several days.
Cramps can be effectively prevented; let's see how.
The published material is intended to allow quick access to general advice, suggestions and remedies that doctors and textbooks usually dispense for the treatment of Muscle Cramps; such indications must in no way substitute the opinion of the attending physician or other health specialists in the sector who are treating the patient.
etc).
- Suspend the use of the involved muscle district.
- Practice specific muscle stretching.
- Massage the affected area.
- Apply warm compresses.
- Diuretics: used in clinics for the treatment of hypertension, in body building for aesthetic reasons and at a sporting level to quickly eliminate the blood traces of doping use.
- Beta-2 agonists (salmeterol and salbutamol): used in the clinic for the treatment of asthma.
NB. Some people with very intense sweating can reduce the onset of cramps by increasing the seasoning salt by about 10g per day (about 4g of sodium).
- Sources of magnesium: whole grains (spelled, wheat, oats, rice, rye, etc.), legumes (beans, chickpeas, soy, lentils, peas, etc.) and dried fruit (almonds, walnuts, hazelnuts, etc.). It is one of the minerals whose recommended ration is more difficult to achieve with food alone.
- Sources of calcium: the main ones are cheese, yogurt and milk. Followed by oil seeds (or dried fruit) and some legumes (some of which, however, are also rich in anti-nutritional molecules).
- Sources of vitamins B: they are numerous and contained in different foods. Some play the role of coenzyme in cellular processes, therefore they must not be missing in the diet of those suffering from cramps. It is sufficient to follow a varied diet without exclusion of food groups (thus avoiding veganism, paleo-diet, etc.).
- Water: the quantity must be comparable to the dispersed sweat.
- Potassium: together with sodium it is the main mineral lost with sweat and urine. Regulates the excitability of muscle fiber cells.
- Calcium: abundant in the body as it is contained in the bones, in the muscles it is the ion mainly responsible for contraction by acting directly on the actin and myosin (muscle proteins).
- Magnesium: is responsible for the inversion of contraction allowing the movement of calcium from one part of the cell to the other.
- Sodium: together with sodium it is the main mineral eliminated with sweat and urine. It is essential for the functioning of the action potential (nerve transmission).
- Maltodextrin or vitargo: semi-complex carbohydrates necessary for a good absorption of the product and to support blood sugar, as well as muscle performance.
- Thiocolchicoside (for example Muscoril®, Miotens®): it exerts its activity through a mechanism of action that involves the antagonization of the GABA-A receptor.
NB. There is no scientific basis to support the hypothesis that stretching reduces the frequency of cramps; on the other hand, being a beneficial activity, it is advisable to practice it anyway.
- Treating diseases potentially responsible for cramps: for some of them the appearance of cramps is only of marginal importance. Some are:
- Kidney failure.
- Chemical-physical damage to the muscular sarcolemma (burns, cuts, lacerations, etc.).
- Nerve infection / inflammation.
