Can Famous Brand Sneakers Achieve Good Results?

There is no way to compare with school uniform, it is more than shoes. Such students often have comparisons with the wind, and "sports performance is about to be included in the entrance examination", which has become the reason why many students ask parents to buy brand-name sports shoes.

How much do good shoes relate to good grades?

Shen Yinghua, a 71 middle school affiliated to Tongji University, has made a survey of sports shoes. The survey has recently won the fifth bronze award of "Shanghai science and Technology Star Award" for young children.

Shen Yinghua believes that now the primary and secondary school students have uniform uniforms, but the sports shoes do not have a uniform style and brand, and the students exercise a lot in the day, so the right shoes are very important.

At present, there are many styles and brands of sports shoes in the market, and prices are also different.

She hopes to provide the basis for selecting sports shoes by measuring the friction coefficient of different brands, men's and women's different styles of sports shoes on the road and the playground with new plastic runways respectively, so as to provide reference for students and parents.

"Some students wear expensive sports shoes and tennis shoes to PE classes. I don't think it is necessary."

According to Shen Yinghua's test results, in terms of the friction coefficient between the sports shoes and the playground, the famous brands abroad are superior to the domestic brands. The friction coefficient of the foreign brand sports shoes is between 0.5 and 0.68, while the friction coefficient of the domestic brand sneakers is between 0.82 and 0.89.

It is unscientific for students to blindly worship shoes.

Xiao Shen said that from the test of the friction coefficient between the sports shoes and the road, there was little difference between them.

"If shoes are mainly used for daily walking, all kinds of sports shoes are not equal to each other."

Wu Xie, an associate professor of biomechanics at Shanghai Institute of Physical Education, believes that from a professional point of view, the choice of shoes in physical education class is unscientific. Tennis shoes, basketball shoes, football shoes and so on, they play different roles. Blindly pursuing brands and ignoring categories, wearing wrong shoes may affect performance.

Moreover, students do not need to be professional in physical education or physical examination at ordinary times.

Even in competitive sports, the result is mainly determined by the strength level of the athletes themselves, not to mention the students' physical examination.

Students take physical examination and choose a pair of light fitting shoes. The most important thing is that students should choose sports shoes according to their actual conditions.
