Hi guys, today let's talk about a very interesting sports topic. Recently at the Paris Olympics, our Chinese swimmers not only achieved outstanding results, but also brought a new fashion that made people shine - wearing down jackets in summer!
A wonderful performance of the Chinese team
Having said that, in the mixed 4×100m medley relay final for men and women, our Chinese team sent a super strong team: Xu Jiayu, Qin Haiyang, Zhang Yufei, Yang Junxuan. They worked hard together and finally broke the Asian record with a time of 3:37.55 and won the silver medal. The United States team won the gold medal with a time of 3:37.43 and set a new world record.
Down jackets in the summer?
Seeing the team members wearing red down jackets one by one, do you also feel a little wondering? After all, wearing a down jacket in summer sounds like a way to warm up Antarctic penguins. But in fact, there is a lot of knowledge behind this.
The importance of keeping warm
First of all, we need to know that the human body will instinctively constrict blood vessels in a cold environment, reducing heat loss on the body surface, so as to protect the temperature of vital organs in the body. As a result, blood circulation in the limbs becomes worse and the muscles become stiff. This is a big no-no for athletes, as even the slightest muscle stiffness can affect their performance.
Scientific research support
Studies have shown that wearing warm clothing can significantly improve an athlete's performance. For example, researchers at the University of East London in the United Kingdom found that swimmers wearing warm coats had an average body temperature 1.55°C higher than when wearing only swimsuits, and their core body temperature also increased. The result? Their 100-meter freestyle time improved by an average of 0.6 percent, or about 0.4 seconds faster. This is really the key to winning or losing in a competitive competition!
It's not just swimmers
Interestingly, this practice is not limited to swimmers. For example, Olympic women's high jumper Yaroslava · Mahuchik even brought a sleeping bag to the track and field to maintain her temperature.
