It is more severe than a contracture (as it also has a blood effusion) and less severe than a tear (unlike the latter, it has no interruption of muscle continuity).
Caused by excessive stretching of muscle fibers, stretching is more likely in certain predisposing conditions (cold muscle, poor training level, uncontrolled or abrupt movement, postural or muscle or coordination imbalances, adverse environmental conditions, repeated microtrauma, unsuitable clothing , insufficient recovery / compensation, etc.).
The body has a specific defense mechanism against this type of trauma. It is called the stretch reflex. It consists in the instantaneous and immediate contraction of the affected muscle associated with the relaxation of the antagonist muscles. The impulse is generated by the mechanical stress of the neuromuscular spindles present in the stretched muscle. However, it is not always fast or effective enough to prevent tissue damage.
Muscle strain is a fairly common injury in sports and mainly affects the disciplines of: elastic strength, maximal strength, explosive strength, rapidity and speed.
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 a Muscle Strain; 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.
):- Sharp and sudden pain.
- Muscle spasm and motor disability.
- Palpation and functional verification: it is necessary to immediately verify the extent of the damage and to exclude fractures, sprains, etc.
- Ultrasound-type medical imaging: it is more specific and provides detail on the extent and severity of muscle strain.
ATTENTION! Diagnosis is very important as certain aspects of treatment related to strain and tear are diametrically opposed to contracture.
- Application of the R.I.C.E. And "the" English acronym of the words rest (rest), ice (ice), compression (compression), elevation (elevation):
- Rest: a total of at least 2-3 weeks, not only from sport but from any motor activity that affects the affected area.
- Ice: in the form of compresses to be applied to the inflamed area.
- Compression: useful in the application of the pack and also in the form of a bandage.
- Elevation: If possible, the pulled muscle should be held above the level of the heart to facilitate venous return.
- Under medical prescription, take anti-inflammatory and muscle relaxant drugs (see Pharmacological Treatments below).
- Adopt specific medical therapies (see below Medical Therapies).
- If necessary, practice self-stretching under the advice of the physiotherapist.
- Neglecting rest after the injury predisposing to relapses.
- Failure to comply with other specific medical therapies and precautions (see above).
ATTENTION! Stretching in the treatment phase is an activity that can confer benefits or worsen the damage, depending on the specific case and the method.
. However, it may be helpful to increase the intake of anti-inflammatory nutrients:
- Omega 3: they are the eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and alpha linolenic acid (ALA). The first two are biologically very active and are mainly contained in: sardine, mackerel, bonito, alaccia, herring, alletterate, ventresca di tuna, garfish, seaweed, krill etc. The third, on the other hand, is less active but constitutes a precursor of EPA; it is mainly contained in the fat fraction of certain foods of plant origin or in the oils of: soy, linseed, kiwi seeds, seeds of grapes etc.
- Antioxidants:
- Vitamins: the antioxidant vitamins are carotenoids (provitamin A), vitamin C and vitamin E. Carotenoids are contained in vegetables and red or orange fruits (apricots, peppers, melons, peaches, carrots, squash, tomatoes, etc.); they are also present in crustaceans and milk. Vitamin C is typical of sour fruit and some vegetables (lemons, oranges, mandarins, grapefruits, kiwis, peppers, parsley, chicory, lettuce, tomatoes, cabbage, etc.). Vitamin E can be found in the lipid portion of many seeds and related oils (wheat germ, corn germ, sesame, etc.).
- Minerals: zinc and selenium. The first is mainly contained in: liver, meat, milk and derivatives, some bivalve molluscs (especially oysters). The second is mainly contained in: meat, fish products, egg yolk, milk and derivatives, enriched foods (potatoes, etc.).
- Polyphenols: simple phenols, flavonoids, tannins. They are very rich: vegetables (onion, garlic, citrus fruits, cherries, etc.), fruit and relative seeds (pomegranate, grapes, berries, etc.), wine, oil seeds, coffee, tea, cocoa, legumes and whole grains, etc.
Your doctor may advise you to take:
- Non-steroidal anti-inflammatory drugs (NSAIDs): for systemic or topical use (ointment, gel or cream):
- For systemic use - tablets and suppositories:
- Ibuprofen (e.g. Arfen®, Moment®, Brufen®, Nurofen®)
- Diclofenac (e.g. Voltaren®).
- Naproxene (e.g. Aleve®, Naprosyn®, Prexan®, Naprius®).
- For topical use - creams, ointments and gels:
- Ibuprofen 10% lysine salt (e.g. Dolorfast®).
- Ketoprofen 2.5% (e.g. Fastum gel®, Ketoprofen ALM®, Steofen®).
- Diclofenac (e.g. Voltaren®).
- Muscle relaxants: they relax the skeletal and smooth muscles. They can be for oral (systemic), parenteral (injection) and topical (ointment, gel or cream) use. They exert their activity through a mechanism of action that involves the antagonism of the GABA-A receptor. The most used in stretches are those that act on the central nervous system:
- Suxamethonium chloride (e.g. Myotenlis®).
- Thiocolchicoside (e.g. Muscoril®, Miotens®).
- Technical clothing in the winter months.
- Specific ointments.
- Increase the temperature of all the muscles used in the athletic gesture.
- "Stretching" the tissues of the structures recruited in the athletic gesture (muscle bundles, sheaths, etc.).
- ATTENTION! Stretching can be beneficial or harmful depending on the time, type and intensity. It is advisable to always perform it hot, not immediately after strength exercises and / or muscle exhaustion and without straining or bouncing.
