Also known as: Magic Swimsuit, SPEEDO Swimsuit, LZRRacer Swimsuit, Fast Leather.

English name: shark skin swimsuit

In the swimming competition of Sydney Olympic Games, ian thorpe, an Australian, wore a black one-piece swimsuit, like a shark moving in the blue waves, breaking the waves and winning three gold medals in one fell swoop. His shark skin swimsuit became famous in the swimming world.

Shark skin swimsuit is nicknamed according to its appearance. In fact, it has a louder name: Kuaipi, and the core technology is to imitate shark skin. Biologists have found that rough V-shaped wrinkles on the surface of shark skin can greatly reduce the friction of water flow, make the water flow around the body more efficient, and sharks can swim quickly. Fast skin's ultra-stretched fiber surface is completely made by imitating the surface of shark skin. In addition, this swimsuit also fully integrates the principles of bionics: imitating human tendons at the seams to provide power for athletes to stroke backwards; Imitate human skin on the fabric, which is elastic. The experiment shows that the fast skin fiber can reduce the resistance of water by 3%, which is of great significance in the swimming competition where 1% seconds can decide the outcome. 1999 10, FINA officially allows athletes to wear fast leather to participate in the competition.

For years, people have been exploring what kind of swimsuit to wear to swim faster. The resistance that swimmers encounter in water is directly proportional to the density of water, the frontal lobe area of swimmers, the friction coefficient and the square of the speed of swimmers, so reducing the frontal lobe area and friction coefficient is the key to designing low-resistance swimsuits.

First generation shark skin

FASTSKIN in 2000

Imitating shark skin structure with fiber can guide the surrounding water flow, reduce water resistance and improve swimming speed by 3% ~ 7.5%. As a representative of shark skin, this swimsuit was popular all over the world in Sydney Olympic Games, and 83% of the contestants chose to wear shark skin to participate in the competition.

Second generation shark skin

FASTAKIN 2 in 2004

On the basis of 1 generation, adding granular dots on the surface of the fabric reduces the water resistance by 30%, and the overall functional ratio of 1 generation increases by 7.5%. In the 2004 Athens Olympic Games, 47 athletes who won medals walked onto the podium in this swimsuit.

Third generation shark skin

FASTAKIN FS_PRO in 2007

It consists of oxygen-isolating elastic yarn and superfine nylon yarn. Its elasticity is 15% higher than that of similar products, which can reduce muscle vibration and energy loss. In 2007 1 year, he helped athletes from all over the world break the world record of 2 1 time.

The fourth generation shark skin

2008 FASTSKIN LZR racing car

The fourth generation is made of LZR Pulse fabric, which has extremely light weight, low resistance, waterproof and quick-drying performance. It is the first wrinkle-free competition swimsuit produced by high-tech welding in the world. In the past 1 month 16 new world record, there are 14 items created by swimmers wearing this bathing suit.
