Why don't male divers have body hair?

Swimming is a big sport, and Phelps is recognized as the world's swimming overlord. He once created the miracle that Beijing Olympic Games swept all competitions and won eight gold medals. China's swimming events also have certain strength. In recent years, except Sun Yang, a male athlete, Ye, a female athlete and many other famous athletes, they are all world-famous swimmers. Swimming can not only bring us wonderful performances, but also appreciate the "devil figure" of many beautiful and handsome men. One detail, I don't know if you have noticed, all athletes have no armpit hair. Why? Let's get to know each other! Knowledge of swimming coldness: Why don't swimmers have armpit hair?

Why don't swimmers have armpit hair? There are three main reasons: first, water has a certain viscosity and fluidity, and you can feel great resistance when swimming, and hair will increase this resistance to a certain extent. Although the impact is small, we know that there are differences in the final competition among many masters, so athletes should try their best to eliminate all factors that affect them in order to achieve the best results. Secondly, when an athlete swims, if there is armpit hair, the armpit hair will swing with the current, so that the armpit hair will constantly beat the skin around the armpit, causing certain discomfort to the athlete. Moreover, it has been proved that the swing of armpit hair during swimming will damage the skin, and this damage can be avoided.

In fact, male divers also have troubles, not necessarily less than female divers. It can also be described as "too difficult". As we all know, athletes need high-intensity training every day. Take diving as an example. When diving, they have to deal with water every day, and the impact of water will have a great impact on their eyesight. Guo Jingjing's vision dropped to 0.2. After training day and night, they will inevitably encounter injuries, and physical pain will also affect their competitive state. So what happened to the male athletes? Diving male athletes are "too difficult": short swimming trunks are worried about attracting attention, and strong body hair is also a hidden worry. First of all, this female athlete needs to shave, but shaving is more important for male athletes than for female athletes. First of all, shaving can improve the swimming speed by 2%, which is more important for swimmers than divers. The second is to avoid unnecessary embarrassment. Because male athletes wear less than female athletes, hair is easier to see, especially the hair in the lower abdomen.

Second, the swimming trunks are too short. Divers' swimming trunks are very short and only cover important parts. This is embarrassing, too. The trouble for male athletes is that the swimming trunks are too short, which may attract the attention of the audience and change what everyone pays attention to. It may not be the athlete's grades, but his swimming trunks. In addition, the diving range is too large, which will lead to the deviation of swimming trunks. Sometimes when people are not looking, they will pull and adjust their positions. Because I have participated in many competitions and am used to wearing such short swimming trunks, athletes with good figure will become a hot topic for the audience.
