Wear The Joints Of High Heels And Affect The Birth Of 10 Centimeters.

Narrowing the female pelvis affects natural childbirth. High heeled shoes are women's favorite, but wear them for a long time. High-heeled shoes It will also affect women's fertility, and very few people will know. From the point of view of human physiology, when a woman walks on high heels, the body must tilt forward. Such a stress position will aggravate the pelvic pressure. The pelvis is forced to shrink inside the pelvis, increasing the inclination angle, resulting in narrowing of the pelvic inlet. As the pelvis narrows, the passage of the baby's mother's body also becomes narrower, so the number of women who achieve spontaneous labor in recent years is less and less.

accelerate Joint wear And degeneration causes low back pain. Wearing more than 5cm high heels, the body will not adapt. Because this will increase the lumbar forward protrusion and move the gravitational line backward. Facet joint shearing Stress increases, which can cause degeneration and instability, and at the same time cause injury to the external muscles and core muscles of the waist and abdomen. The release of inflammatory mediators can lead to chronic back pain.

As the heel is lifted up, the center of gravity will fall on the forefoot, which will make the ankle joint unstable and prone to the risk of ankle sprain. Not only that, it will also affect the knee joint, because the center of gravity line falls in front, so the knee tends to have a backward facing condition, that is, over stretched. This condition will accelerate the joint wear and degeneration, causing knee pain and a series of diseases such as synovitis of the knee, patella softening and osteoarthrosis.

Therefore, experts remind that women wear high-heeled shoes should pay attention to the following points: 1. wear high heels should not be too long, not long standing and walking. 2. don't be too careful with your heels, so as not to fall. Heel height is best within 5 centimeters. If you wear 10 centimeters of high heels, you should add some cushions to relieve the pressure inside the shoes, which can relieve the pressure of the front feet and reduce the negative gravity of the spine. 3. it is recommended that women under the age of 18 and over 50 do not wear high heels.

The size of the shoe and the shoe last are the basic choice, but the shoe type of each shoe factory is different. For example, Adidas's last is usually relatively narrow, and ASICs is usually relatively wide. Different brands may be half or half last, so they can't be judged only by size, or if they are actually crossed.

When the foot touches the ground, it moves on the inside of the foot with the medial side of the foot. At last, it slightly leaning back to the middle of the front foot. It may be completely moving inside the sole of the foot. This situation is more common in runners with low arch or flat feet. It needs stable structure to support the medial arch of the arch. The shoes selected are mainly of stable type.

Excessive internal rotation refers to the over rotation of the foot, or the rotation of the foot when it is not supposed to rotate, for example, the late stage of the whole palm in the gait cycle. At this point, the inner side of the foot will bear too much weight. When the runner advances, the load will be borne by the inner edge, not the front foot. This can lead to instability of the feet, which will not only affect the efficiency of running, but also cause obstacles to running.

Runners with excessive internal rotation should consider running shoes with high supporting functions, providing enough rigidity for the inner side of the arch, and effectively improving the stability of the feet. On the Internet, the way of judging the movement of the sole of the foot is often based on the arch of the foot. It can only be said that this is a general situation, and there are runners who are low arch but lack of internal rotation, or high arch but excessive internal rotation. The actual situation is still judged by the wear of the sole or the movement of the running feet on the treadmill by professionals.

Running is a dynamic behavior. Don't talk on paper, choose shoes on the sole of your feet. In addition, Neutral (cushioning), stability (Stability, Structural Cushioning), motion control (Motional control), etc. shoes are classified or addressed to each shoe factory slightly different. When choosing shoes, you should pay special attention to it. You can browse to each shoe factory website first, note down the correct classification and try again.

With the change of running experience and physical quality, weight and movement of the sole can be changed. Every time we choose shoes, we should judge the basis of the recent wearing shoes and the feeling of running. We should make adjustments at any time, try different kinds of shoes, get the best protection for both feet, and also have the best running efficiency.
