The hamstrings are the muscles that are in the posterior leg . They arise in the hip bone that is called ischium and they are inserted in the fibula and in the tibia .
He sciatic nerve It is responsible for the innervation of the hamstrings, which fulfill various functions in actions such as jumping and running. The hamstrings are flexors of the knee and hip extenders.
He semitendinoso , he semimembranous and the femoral biceps They are some of the hamstrings. This musculature can suffer from various pathologies and injuries that cause difficulties when performing physical activities.
Inactivity, for example, can lead to shortening of hamstrings, which begin to become stiff and make it difficult to develop certain movements or efforts. To avoid this problem, you have to lead an active life, minimize muscle imbalances and have a nutrition healthy.
Who practice sports which involve sudden exits and arrests, such as tennis, basketball (basketball) and football, are at greater risk of suffering a hamstring injury due to stretching or tension. This can cause acute pain, tenderness and swelling.
The most common treatment for hamstring injuries usually includes rest, compression bandages, ice packs and the supply of pain relievers to combat pain and reduce inflammation. The physiotherapy for muscle strengthening is also recommended. Anyway, a doctor is the professional who must analyze each case individually and indicate, according to their knowledge, the steps to follow.
It is worth mentioning that this muscle group that we call hamstrings has a force considerable tendonous. The injuries that are caused in them more frequently are the strains , the muscle contracture and the fiber breakage .
We understand by hamstring strain the elongation of the various structures of tendons that constitute the posterior muscles of the thigh. One of the most common characteristics of hamstring strain is the intense pain that occurs in the back of the thigh. It is a very common disorder in athletes, and is usually accompanied by tears in the area of the biceps femoris.
The possible causes of this problem are several; Let's look at some of them below: do not warm up sufficiently and adequately before exercising, especially if it is an intense session; weakening of the muscles that prevents reaching a good level of performance; tiredness due to lack of rest between the moments of greatest activity .
As mentioned in a previous paragraph, sports in which explosive movements occur increase the chances of suffering hamstring injuries. These movements can be a jump, a ball attack or a sudden and sudden change of pace.
The severity of the distension of the hamstrings serves to establish a classification:
* slight : the stretching or breakage of a muscle fiber occurs, which causes slight discomfort to the subject although it does not cause a considerable loss of mobility. This injury can occur even without the person noticing it at the moment, and in this case the discomfort comes after a few hours;
* moderate : it is about the breakage of certain fibers of muscles and tendons, which causes pain when feeling the affected area. It may be accompanied by mild swelling and some discomfort when walking or running. In these cases, the subject does tend to interrupt his physical activity as soon as the injury occurs;
* serious : A hamstring strain considered severe is a fiber break or a really important tendon insert. When palpating the area there is a clear default muscle and movement capacity is greatly reduced.
