Wearing a bathing suit reduces drag by 7% compared to nude swimming

At the beginning of the Olympic Games, swimsuits were made of cotton plain weave and rib fabric, which was lax and carried water, causing great resistance. Wool and silk fabrics gradually made swimming suits more compact and close-fitting.

For a time, however, the absurd and banal morality of swimming suits was heretical. The seventh Antwerp Olympic Games gold medalist in three swimming, "flying fish" bright ray of the United States was arrested for swimming in shorts on the beach, "Taoist" gave her Ann was accused of "indecency.

In 1975, Dutch researchers conducted a controlled experiment in the boat holders' tank with and without swimwear, and found that the resistance of swimwear was 7% lower than that of nude swimming. The reason is that human beings, as four-legged animals, through this "wrapping" and covering, can make the whole body curve more smooth and close to streamline, and thus the "wear and take off" of swimming suit is over.

In 1988 Seoul Olympic Games, the "strongman" swimming suit of the United States team attracted much attention. Polyurethane fiber and ultra-fine nylon fiber not only reduced the weight of the swimming suit again, but also achieved excellent bidirectional scalability and overall smoothness.

The 2000 Sydney Olympics became a showpiece for sharkskin swimwear.
