Why can't primary school students often wear sports shoes?

Wearing sports shoes for a long time is not good for human health, especially for children who are growing up. The manufacture of sports shoes is designed according to the characteristics of people traveling abroad. The commonly used materials are mostly nylon, plastic, hard sponge, etc. The bottom of the shoe is flat, soft and elastic, which is not only light and wear-resistant, but also waterproof and warm, suitable for walking in the wild, mountaineering and long-distance travel.

However, if you wear sports shoes for a long time, your feet will sweat easily, and the damp heat in your shoes will also lead to the redness of your feet over time. Because it is suitable for the reproduction of mold and bacteria, it is easy to cause tinea pedis. Because most sneakers are flat-bottomed, when people walk and exercise, the body load is unevenly distributed on their feet, which will affect the average distribution of the body's center of gravity on the soles of their feet and affect the normal state of muscles, ligaments, spine and spine. In the long run, it will do great harm to human health, especially to growing children.

Due to the increase of temperature and humidity in shoes, students' plantar ligaments tend to become loose and elongated, and the soles of their feet gradually become wider, which can become flat-bottomed feet over time. Rubber, plastic, sponge, nylon, canvas, etc. Most of them are used as materials for travel shoes. These materials have poor air permeability, and students are in a period of vigorous growth and development. Coupled with exercise, sweat is secreted from their feet. Sweat is difficult to radiate from sweaty feet in this "closed" environment for a long time, which is easy to cause the propagation and spread of fungi, and dermatoses such as beriberi, dermatitis and eczema appear.

Sports shoes or travel shoes are flat shoes without heels, which can not ensure that the center of gravity of the human body is evenly distributed on the whole sole, and can not keep the muscles, ligaments, bones and spine of the body in normal positions and working conditions. The change of body gravity after students put on sports shoes or sneakers makes the stress distribution on their feet uneven, which can affect their gait. Being in this bad environment for a long time will affect the physical development of teenagers.

Therefore, unless you participate in sports activities or travel abroad, try to wear sports shoes and travel shoes as little as possible. In addition, the ideal heel height of sports shoes is 2-3 cm, which can ensure the proper distribution of human center of gravity.

What shoes should pupils wear for long-distance running in winter?

First, long-distance running in winter, do not wear "rice fish" canvas shoes.

Canvas shoes, commonly known as "rice fish" in Guangdong, have canvas shoes and thin rubber soles, and were once called rubber shoes. "White rice fish" has become a trend vane since it squeezed into the fashion circle, and it has been enthusiastically sought after by students' brothers and sisters, and has also become a common sports shoe in physical education class in primary and secondary schools.

But experts pointed out that this kind of rubber-soled shoes based on canvas is not a special sports shoe. Its body design is too soft and its shock absorption function is poor, especially the heel cup and midsole are not thick enough. Students should not use canvas shoes as sports shoes for a long time.

4- 14 years old is the growth and development period of children's bones, joints and ligaments. Once you wear shoes that are not suitable for all kinds of sports in physical education class, its influence will not only hinder the development of foot bones, but also increase the chance of ligament sprain.

Second, wear sports shoes with protective design.

Speaking of long-distance running, especially the 2000-meter long-distance running, it is not an easy sport for children whose feet are still developing. What shoes can you wear to cope with the relatively strenuous exercise of running and reduce the chance of injury?

Xx told reporters: "Students should wear professionally designed sports shoes, such as healthy sports shoes with the concept of" three feet "to protect their developing feet."

What are three kinds of sports shoes to keep feet healthy?

First, the sole should have a shaped midsole to support the weight, absorb the vibration, strengthen the support of the foot, and reduce the fatigue and foot pain when running 1000 meters or even 2000 meters.

Second, there should be a hard heel cup to stabilize the calcaneus and prevent calcaneus sprain.

Thirdly, running shoes need arch position to support gravity, and suitable insoles are matched according to children's different foot types to relieve leg pressure and fatigue.

Third, be prepared before running and protect your feet.
