Regarding the Achilles tendon and leg muscles, which part of the Achilles tendon is

When people stand on tiptoe with their heels off the ground, there is a very thick, strong, and tight tendon between the heel and the calf, which is called the Achilles tendon. It is one of the most powerful tendons in the human body by combining the tendons of two muscles, the soleus muscle, which originates behind the tibia, and the gastrocnemius muscle, which originates from the medial and external condyles of the femur. People walk, run, and jump rely on this powerful tendon.

If the Achilles tendon is completely broken, it will be difficult to move an inch. Legend has it that in ancient times, the Achilles tendons on both sides of a person were cut off as a punishment. There are many chances of Achilles tendon rupture occurring in daily life and work.

One is a direct cut from something sharp. At this time, ** is always injured together, and the ruptured tendon can be seen through the wound. This is called an open Achilles tendon rupture.

The second is when the Achilles tendon is under tension, is subjected to a lateral smash, or is ruptured due to a sudden and violent contraction of the muscle. At this point, ** often remains intact and is called closed Achilles tendon rupture. In another case, the Achilles tendon is maltrophied due to long-term chronic damage or cortisone injection, and the Achilles tendon has degenerative changes or calcifications, which weakens the strength of the Achilles tendon and is susceptible to stretching and rupture.

This tends to happen to dancers or track and field athletes. In open Achilles tendon injury, the severed end of the Achilles tendon can be seen in the wound, and diagnosis is not difficult. For closed Achilles tendon injuries, the patient's history of the injury should be carefully questioned.

Patients often recount a typical history of injury, with loud noises and a feeling of breaking, followed by pain, weakness, and inability to lift their heels. In addition to local swelling and tenderness, the ankle is weak in plantar flexion. When the patient is instructed to lift the heel vigorously, a transverse depression can be felt at the rupture of the Achilles tendon, and there is significant tenderness.

Fresh open Achilles tendon rupture should be performed as soon as possible to surgically close the Achilles tendon. If the closed Achilles tendon rupture is considered to be complete, it should also be sutured in time, otherwise the upper end of the tendon will shrink upward due to the contraction of the gastrocnemius muscle, and separate further from the lower end, resulting in difficulty in suturing. After suturing, the knee joint is placed in the flexion position and the ankle joint is placed in the plantar flexion position with a long-leg plaster cast.

After 3 weeks, it was replaced with a functional cast and fixed for another 3 weeks. Walking practice began 6 weeks after surgery. If the old Achilles tendon ruptures are present, the Achilles tendon should be repaired with special methods.

The 10-meter moving target Sydney Olympic champion Yang Ling was ruptured in Achilles tendon due to badminton before the game, and missed Athens such as athletes and actors. After the Achilles tendon rupture heals, after gradual functional exercises, quite satisfactory results can generally be achieved. Athletes and people engaged in related occupations should pay attention to protection, scientific arrangements should be made during training and activities, use protective belts, and prevent excessive exercise.

<> "A little anatomical knowledge a day, Achilles tendon.

1. Introduction. When we stand on tiptoe, there is a very thick, strong, tendon between the heel and the calf, which is called the Achilles tendon. It is one of the most powerful tendons in the human body by combining the tendons of the soleus muscle, which originates from the soleus muscle, which originates from the franial condyle, and the gastrocnemius muscle, which originates from the medial femoral condyle.

People walk, run, and jump rely on this powerful tendon. If the Achilles tendon is completely broken, it will be difficult to move an inch.

2. Structure. The Achilles tendon is about 15 cm longIt is the thickest sharp tendon in the human body.

It is formed by the fusion of the triceps muscles of the lower leg (soleus, gastrocnemius, microcephalic) tendons about 15 cm above the heel. Distinct strip-like protrusions form on the surface of the body. The main function of the Achilles tendon is to flex the calf and plantar flexion, and the person is able to jump.

It is all about being able to run on the ground. In addition, tendons also affect the erection of the person.

3. Function. The function of the Achilles tendon is to be responsible for the flexion of the bare joint. That is, we do the action of tiptoeing, the Achilles tendon is the most important anatomical structure of the calf muscle power to convey the strength of the king's foot, and it is an indispensable tissue for human beings to stand, walk, run, climb and other sports.

Studies have shown that the Achilles tendon is about 900 kg of body weight when running fast. When jumping or riding a bicycle, the force is 6-8 times the body weight. In other words, if you have a problem with your Achilles tendon, you may lose even the most basic lower limb movements, so it's very important!

Miho. 4. Achilles tendon rupture.

If the Achilles tendon is suddenly overstretched by force, it may rupture completely or partially. Achilles tendon rupture is most common in body movements, but other injurious elements can also cause Achilles tendon rupture. The location of Achilles tendon rupture is usually within 6 cm of the Achilles tendon insertion point, where the blood supply is less, and the healing ability is also poor.

When the curved Achilles tendon is ruptured, when the calf exerts force, you suddenly hear a "bang" or "pop", and you feel that the calf has been kicked. Severe pain and swelling immediately in the back of the heel and calf, inability to walk or tiptoe.

Maintain walking, standing, and balance.

Traditionally, under the same conditions, those with a longer "Achilles tendon", i.e., a greater value of 100 (fibular tendon length and calf length), have a relatively stronger ability to run and jump. People often exaggerate the correlation between the length of the "Achilles tendon" (actually the gastrocnemius tendon) and the bounce force, and even think that the length of the "Achilles tendon" determines the bounce force.

Many recent studies have shown that gastrocnemius tendon length, calf length, and Achilles tendon length calf length are not related to jumping ability, which is inconsistent with conventional wisdom. The possible reason is that the tendon is a high-strength and low-deformation biomaterial, which does not provide power during movement, it is pulled by the muscle to produce movement, and its exercise ability is related to the size of the muscle traction.

Exercise calf project, if you want to do 3 sets of one movement, rest between groups can not exceed 2 minutes, if you are done, you need to do the next project directly, remember not to rest!

The first item: half-squat jump.

1. At the beginning, in a half-squatting position, place your hands in front of you, 2. Jump up at least 20 to 25cm from the ground. When in the air, keep your hands behind your back. When you land, finish it once.

Next, just repeat the steps above!

The second item: raise the toes (calf raises).

1 First, find a step or a book to put on your feet, and then put your toes on top only, with your heels not touching the ground or padding, and lifting your toes to the highest point.

2 Slowly lower it again and finish it once Finish with both feet and complete a set.

The third item: steps.

1.Find a chair, put one foot on it, at 90 degrees, jump away as best you can, change your foot in the air, put it on the chair, 2Repeat, put the original jump foot back on the chair to complete the other jump.

Fourth: vertical jump.

1.Keep your feet shoulder-width apart"Lock"Knee. Jump with only your calves, bend only your feet, and try not to bend your knees.

2.When you reach the ground, take off quickly again and complete it again.

Run every day and do pull-ups.

The main reason for the Achilles tendon to grow is to make you jump higher.

If you practice well, the proportions are not clear, and in short, your calf muscles are quite tight. And your calf muscles look like they're being pushed up by your Achilles tendon. Just look at the shin legs of the NBA guys.

It has to do with the force on your calves when you exercise!
