Muscle contraction:Â Involuntary contraction means a coordinate of a set of fibers and muscle cells within a muscle. It usually comes as part of a sport and stands as a painful sensation of stiffness in a muscle. It differs from simple muscle cramp discomfort felt by a longer duration. The muscle must be put to rest and pain can be treated with stretching, massage or application of warm compresses and ointments.
The Different Types Of Muscle Contraction
You may have heard of concentric contractions, eccentric and isometric. These terms relate to complex concepts essential to a good workout. So take the time to describe the specifics of each of these contractions in order to better understand how they will be involved in training.
The concentric contraction
This is the best known type of contraction. The concentric contraction causes swelling related to the approximation of the contractile units of the muscle.
For example, if you take a glass on a table to drink its contents, you bring the glass to your mouth by performing a concentric contraction of the biceps.
The concentric contraction of agonist muscle (see article) will enable the realization of the movement.
We can also compare the concentric contraction to the withdrawal of a jack to lift a load.
The Eccentric contraction
If you understand the concept of concentric contraction, you will understand very easily the notion of eccentric contraction.
This is the contrary. The eccentric contraction is associated with a muscle stretching.
For example, if you rest a drink on a table after drinking its contents, you bring the glass from the mouth to the table by performing an eccentric contraction of the biceps.
Thus, the eccentric contraction of the antagonist muscle to control the movement and curb. Without it, your glass fall on the table.
The concepts of concentric and eccentric contractions are strongly linked to notions of agonist and antagonist muscles.
One can also compare the eccentric contraction to the extension of an actuator to return to its initial position.
The isometric contraction
If both types of contractions, as we have just seen, are related to movement, isometric contraction is characterized by an absence of movement.
It is therefore the contraction of the muscle to withstand without any constraint of joint movement.
For example, if you try to lift too heavy a burden, you will contract your muscles to the maximum but still, you will not be able to move the load.
This mode of contraction is associated with a period, that of the contraction, in contrast to other methods that are associated with a number of repetitions.
Isometric contraction is generally considered to be the one that produces the maximum voluntary strength.
What Causes Muscle Contractions:
This term, used rather in sport, define an involuntary muscular contraction of a number of muscle fibers of a muscle or group of muscles. It differs from the cramp by a much longer duration. Often painful, it is generally not associated with a lesion of the muscle fiber. Main affected muscles? Thighs, calves, buttocks, gutters spinal and neck. Contraction may result from a reflex contraction that aims to protect the muscle as a result of a significant stretch. Second possible origin: significant fatigue of the muscle resulting in disorders of certain molecules at the cellular level, such as calcium, potassium, magnesium. Contraction may be also due to a defense mechanism, generated by a stiff neck, sprains, lumbago …
Symptoms of Muscle Contraction
The pain is first felt after exercise, during moments of rest. If the force is continued, the muscle tensed increasingly. The pain becomes sensitive during the year, then very annoying at the end of the latter.
The pain is very localized. A hard point is revealed by palpation. The muscle is painful on the part Contraction during passive stretching and during contraction against resistance. Contraction can be diagnosed by a simple clinical examination. Do an ultrasound is useless: indeed,the latter revealed no anomalies.
Muscle spasm often occurs during sports practice or other strenuous activity. It begins with localized pain, minimal at first, then becomes increasingly annoying especially if physical activity is not interrupted. If one feels the painful muscle include a hard contracted muscle, sometimes you can find a real cord well drawn in the same seine of painful muscle, it represents the muscle fibers contracted especially during passive stretching against resistance or maneuvers.
Moreover, in muscle contraction reflex is an abrupt contraction following joint trauma with blocking it (no motion possible). The diagnosis in this case is easy and obvious.
Finally, it is easy to differentiate muscle contractionÂ muscle cramp its duration is more prolonged in the first situation.
Treat and relieve muscle Contraction
First, the affected muscle should be rested. It is possible to put a warm compress wrapped in a cloth on the painful area or thermal pad Coldhot heated for 20 to 30 minutes. Massage can relieve, with or without cream or physiotherapy exercises with progressive stretching device after a few days .. Sometimes muscle relaxants (muscle relaxants) and analgesics (struggling against the pain) are prescribed. Contraction can last from 5 to 10 days.
Upon occurrence of muscle spasm, the first thing to do is to stop the current activity and put the muscle at rest, remember: muscle contraction is an alarm your body sending signals directing you to stop immediate muscular effort.
Make applying heat to the painful muscle (wrapped hot compress on the area contractionÂ for 30 minutes), it is also whether one is at home taking a warm bath for 20-30 minutes.
There are also ointments relaxants (Srilane *) are effective, there are also muscle relaxants and painkillers (paracetamol or ibuprofen) to help relieve pain.
Moreover, muscle contraction can last several days and usually disappear after 05-07 days.
How to prevent muscle contraction?
Prevention starts with training. It is also essential to warm up correctly before an activity. Having a proper diet, hydration, heat up and provide a suitable muscular effort are the basic rules for protection of this muscle failure, not serious but painful and embarrassing.
The intense and brutal physical stress is the main cause of muscle spasms, prevention is to always warm up before any significant physical activity for sport, but also for other domestic activities or work.
Sufficient hydration is also important, especially when heat, hydrate before and during sport by fractional quantities and rich mineral, in effect, sweating is the main cause of loss of minerals due to contractions and cramps.
The rest and recovery after physical exercise or sport allows the muscles to regenerate and adapt as and measure activities more and more intense and more prolonged.
