As we all know, in daily life, many girls often solve their own hair. Especially in the hot summer, in order to put on sexy clothes better, ladies will undoubtedly shave off their hair often, so as to leave a good impression and not look dirty and sloppy.
Swimmers are not like other athletes. They have to wear swimsuits in competitions, so it is inevitable that some parts of their bodies will be exposed to audiences all over the country or around the world, such as underarms. Especially for female swimmers, if there is hair, it will do some harm to their brand image.
Isn't it more manly for male athletes to keep shaving? Why do they shave too? Swimmers should not only get rid of hair, beard, leg hair and body hair, but also get rid of it early. In addition to the harm, there is another very important reason, which you may find unbelievable: that is, the shaving of swimmers will reduce the friction resistance during swimming and improve their performance.
Friends who have watched the swimming competition may know that in the swimming competition, the results of the champion and the third runner-up may be only a few tenths of a second, or even shorter. Don't think that this is only a few tenths of a second, and swimmers are likely to have to invest a lot of sweat to get it.
The research of the relevant departments of the Swimming Association shows that the hair on the human body will cause sliding friction during the whole swinging process of swimmers, and this sliding friction can cause about 0.2% slight injury. Don't underestimate the harm of 0.2%, it may have chosen the first place. The "shark skin" swimsuit, which was originally stopped, has the same function as shaving, in order to better reduce the friction resistance in the water. In addition to maintaining the brand image, getting points and putting an end to shaving, there are also security considerations.
Why is it for security reasons? This is mainly because in swimming competitions, swimmers' shaving is likely to fall off. Because the level of competition is fierce, shaved hair may be sucked into athletes' bodies at risk, and if it is too much, it may endanger athletes' eyesight.
This is why people will find that swimmers wear swimming caps when swimming. In fact, this is the same as removing shaving. In addition to reducing friction resistance, it is also important to get points and reduce the risk of hair coming out of water.
