SHIN SPLINTS

This is a general term for pain in the lower legs of athletes. The condition may be due to various conditions including stress fracture, poor mechanics and execution specialized syndrome.

Shin rails is a generic term that refers to a painful condition in The Shins.

Shin rails is often caused by running or jumping and can be very slow to heal. Freestyle skiers often suffer from shin rails emphasis on the shin while landing a jump. This is a common injury caused by cross-country runners.

There is no cure for direct shin splints, to heal and rest.

The special conditions

Inflammation of connective tissue

Shin pain can also the result of inflammation of connective tissue such as bone skin (periostitis). The pain can be a stress fracture in the bone or other problems such as osteosarcoma. Pain in the lower leg may also be denominated in a remote area of the body, such as pressure on the sciatic nerve (sciatica) close to the common foot.

-- Chronic disease specialist

One problem that can imitate front shin rails is the chronic-disease specialist (CCS). This is a serious problem that could cause a significant loss of function in the lower leg. CCS occurs when the swelling within indistensible front of the leg reduces the flow of blood. This relative lack of blood, ischemia can lead to more swelling and generate a positive feedback loop. In severe cases, the result specialist acute syndrome (ACS) requires emergency operation to prevent ischaemic necrosis muscle, bone, muscle death due to lack of blood.

Diagnosis

Just think, if CCS constantly worst pain during the exercise, instead of improving the ligaments and muscles warm. Formicolio standing is a special red flag, shows nerve compression.

If a bone problem is the suspicion that the cause of inflammation of connective tissue, a bone scan may be useful to confirm the diagnosis.

CAUSE

The purpose of the muscles of the front shin (tibialis above) is on foot dorsiflex (the increase in toe). It may not be clear why a muscle that raises the toe can be stressed or injured by the fact that it is not responsible for the unit. The reason is that the runners overstride unskilled and land heavily on the heel with each footstrike. If this happens, the front quickly slaps on the ground. Del foot, which is dorsiflexed first contact with the ground, is strongly expanded. This powerful extension of the toe leads to a similar fast-attached muscles. A reflection responds to the muscles, resulting in a powerful contraction. And 'this eccentric contraction of the muscles leads to pain and possible violations of muscles, tendons and connective tissue.

Similarly, improper pronation of the foot during the footstrike can also pain in the muscles against pronation on the inside or outside the shin. In good pronation of the foot strikes the ground on the outside of the heel and then rolls on the inside of the foot about 5%. The ideal degree of pronation slightly varies with the individual. It is determined by factors such as the height of the arc (more arc has more clearance for pronation as a low arc) and flexibility of the arc. In more than pronation, the foot rolls too far. The result is that pushes your foot off almost entirely from the big toe, causing excessive for the great toe and outside the tibia. On the contrary, under pronation occurs when the foot is not sufficient to roll. This means that the entire weight of the foot strike to focus on too small for an area outside the resort at the foot a burden on the shin.

It is also generally believe that a contribution due to shin saver muscle pain, in some cases, the relative weakness of the muscles of the front row lower than those of the calf. In this case, which prefers the front exercises to strengthen muscles can help reduce or prevent shin rails. Shin pain is attributed to a forced extension of the muscles, in this case the opponent calf "saturate" The Shin. During the implementation, has the feeling of extreme hardship.

Treatment and prognosis

CCS

If you suspect CCS consult a doctor before continuing to train. If you suspect specialist acute syndrome (ACS), contact your doctor immediately.

Acute

The immediate treatment for shin rails rest. Implementation and other strenuous high impact resistance leg activities such as football, should be avoided until the pain and subsidies is no longer called for work. In conjunction with rest, anti-inflammatory treatments such as icing and drugs such as NSAIDs may be proposed by a doctor or a coach, although there are some disputes about their effectiveness. Be sure to avoid running on hard surfaces and runs downhill. Some people to treat acupuncture shin rails, but was not conclusive or any study on the effects of acupuncture in shin rails.

Several runners have problems with shin splints, and the main reason is because the runner who hits the ground with the wrong part of his foot. If they are striking the ground with their heel, almost triple their weight will have an impact on the heel, with a painful its power to Shins. During the performance, instead of hitting all your weight on the heel, heel-toe. With the landing at the toes on your heels, the impact will be much easier and the transfer of your foot to heel, and did not cause any strain to The Shins. Although the first week of calves, a small wound, runners must go forward, because it might be used to obtain. This builds muscle tissue in the calf.

Prevention

Training

Like any muscle, the muscles of the front of the tibia can be trained for large static and dynamic flexibility of adaptation, is a reflection contractors, and allow the muscles to connect faster. The key to this is the path regularly The Shins. However, static stretching may not be sufficient. Of adapt a muscle, fast and eccentric contraction, is to acquire a greater dynamism and flexibility. One way to work in dynamic flexibility in front shin subjected to excessive stress in a controlled manner. When the muscle is regularly by an even more dynamic than eccentric contractions during the movement, is more able to cope with normal amount of stress. Experience long-distance runners controlled downhill practice runs as part of training, which places a greater burden on the quadriceps and eccentric Shins. A professional trainer or coach, or perhaps a sports medicine physician should be consulted before engaging in transactions of this type of training.

Posture / forms

The long-term solution to the muscle pain in the shin is a change in the current style for the elimination of overstriding and heavy heel strike.

Wettbewerbsfähigsten runner heel on the ground first. Prepare to toes, unlike the centre distance travelled, where a kind of rolling motion, like dish can be bad for your knees. In transport over long distances running, the footstrike should be flat, although some elite distance runners, retain their acquired earlier strike years in competition with the track and field.

Correction of footstrike begins with the posture. A forward hunched posture leads to a strike heel.

In both positions, the emphasis is on the right foot. This requires physics, because the state is to prevent the body from over. An object falls halfway when the focus shifted too in one way or another outside the scope of its support. Arching shifts back of the body center of gravity on the back, so that the front legs tend to have in order to compensate, thus reducing the weight on the toes. Fold forward in life has the opposite effect: The legs tend back in the ankle, shifting the weight heels.

While in operation, the center of gravity is changing rapidly. Since a lot of time there is an extension of unity rear leg, the upper body is tilting forward to compensate for this. This inclination forward is similar to what happens in a position where one leg is raised from the ground and the rear. Inesperti witnessed these runners tilt forward in professional athletes and not to imitate bending at the waist, this is not the same. Forward torso and legs still extended form a straight line, or even a slight curve to the rear:

Shoes

Accent on the shin muscles may also be a little 'shoes and mitigated by the choice of surface. Corridori, strong hitting with the heel should seek shoes, the abundance of rearfoot sponge. [Dubiosen - see discussion] These shoes can lead to "stability" and "Motion Control" shoes. The so-called "neutral" shoes for bio-mechanically efficient runners may not have sufficient support in the heel because the runners, these shoes are not required. If their capacity tapestry degraded, the shoes should be replaced. The most common recommended interval replacement for the shoes is 500 miles or 800 kilometers. Pronation excessive can be reduced by an additional support under the arch. Shoes racing with a significant support to the belly under the arch are called "motion control" shoes, because the work to limit the movement offset. Even shoes with cushions shock functions and shoe inserts can prevent further problems.
