High-technology swimwear

Last updated

High-technology swimwear, or tech suits, are scientifically advanced materials used for swimwear in competitive water sports such as swimming and triathlon. Materials of this type are normally spandex and nylon composite fabrics with features to reduce drag against the water. [1] The fabrics include features that increase the swimmer's glide through water and reduce the absorption of water by the suit as opposed to regular swimsuits. Additionally, the suits are extremely tight, which make the swimmers body more streamlined and help reduce the buildup of lactic acid in the body. [2] Since 2010, high-tech swimsuits, specifically those offering significant performance-enhancing features and made from non-textile materials, have been banned in professional competitive swimming. This decision was made by FINA after the 2008 and 2009 swimming seasons, during which many world records were broken by swimmers wearing high-tech swimsuits, raising concerns about the impact of technology on the sport. [3] [4] [5]

Purpose and design

High-technology swimwear is designed to reduce drag and improve swimming performance. [6] Speedo claims that their LZR Racer reduced drag or water resistance by 38% compared to a traditional Lycra practice swim suit. [1] This high-technology swimwear is designed to minimize drag while maximizing support to muscles. [1] Some companies claim that their fabrics reduce drag even more than the water's normal friction against the skin. To do this, they design high-end lines of competitive swimwear that cover the arms and legs. The fabric used for high-technology swimwear is light and water-repellent. The material is often composed of highly stretchy spandex and nylon. High-technology swimwear is often made using bonded seams, to reduce further drag. These suits also provide the compression necessary to increase performance. [1]

Regulation

After the 2008 Olympic Games, the International Swimming Federation (FINA) voted to regulate the use of high-technology swimwear in competition. More than 130 swimming world records were broken from 2008 through 2009 through the use of high-tech swimwear. However, FINA unanimously voted to regulate the use of these suits in official competition beginning in 2010. [7] The banned suits used in 2008 and 2009 were polyurethane based. Guidelines as of 2015 have specific measures to regulate the thickness, buoyancy, and permeability of the fabric. [8] The high-technology suits used in competition are no longer able to have zippers or other types of fastening. [8] A large change found in the FINA regulations is the regulations in the design of the suit. Unlike the body suits seen in the 2008 Olympics, men's suits cannot extend above the navel or below the knee. Women's suits cannot cover the neck or extend past the shoulders, or below the knee. [8]

In September 2020, USA Swimming banned 'tech suits' (another name for high tech swimsuits) for any USA Swimming member 12 years or younger competing at any USA Swimming sanctioned, observed, or approved meet, with the exception of Junior Nationals, US Open, National Championships, and Olympic Trials swim meets. [9] These regulations were enacted for multiple reasons, though the main reasons were to lower the cost of participation for young swimmers, and to make sure swimmers were focused on swimming, instead of buying suits. [10]

Manufacturers

High-tech fabric lines by swimwear manufacturers:

Controversy

Advantages

Whether high-tech fabric lines such as these give substantial advantages to swimmers is debated. High-technology suits can increase one's swimming speed by around 4 percent. [1] Other studies suggest that high tech suits are able to reduce drag by around 4–6% and decrease energy cost by a similar amount. Other studies show evidence that in 50-meter races, these suits result in times that are approximately 0.5 seconds faster. [13] A 2012 study, by Joel Stager of Indiana University's Counsilman Center for the Science of Swimming, reportedly found an increase of only 0.34%. [14] Most of the manufacturers counter with their own studies though touting the advantages of their own individual lines overall and against their competitors. Different manufacturers also offer specific advantages to particular types of swimmers—for example, the LZR X is popular among freestyle sprinters for its compression, while many distance swimmers find the compression detrimental to leg muscles over the course of a longer race. Meanwhile, Arena suits are often preferred by breaststrokers for a looser fit, enabling better range of motion while performing a breaststroke kick.

Cost

The materials are sometimes very expensive (USD$300–$600 or GBP£300-£500 for a full suit), limiting their use to highly competitive and professional levels of the sport. Additionally, women's suits are typically much more expensive than men's suits: the TYR Avictor costs $350 for men, [15] but $500 for women; [16] the arena Carbon Core costs $415 for men, [17] but $575 for women, [18] and the Speedo LZR Pure Intent costs $400 [19] for men but $600 for women. [20] However, in recent years with the advance of technology the most basic 'high-technology swimwear' can be purchased for approximately $100 or £100.

Records

Prior to the start of the ban of the high-tech swimsuits at the start of 2010, estimated that over 130 world records had already been broken using the high-tech fabrics. Nearly every medal winner at the 2008 Summer Olympics made use of the high-tech swimwear. This is often seen as the catalyst behind the "technological arms race" in professional swimming competitions including the 2009 World Championships. World Champion American swimmer Aaron Peirsol, who swam two world record times at the 2009 World Championships, said, "A lot of us are joking that this might be the fastest we ever go, we might as well enjoy this (2009) year." [21] Many thought the introduced regulations on high-technology swimwear would end the era of record-breaking performances in swimming, and existing world records currently beaten with the high-tech swimwear be annotated with an asterisk. [22] Nearly two and a half years after FINA regulations were in place nine records were broken at the 2012 Olympics. [23]

Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle.

Arena X-Glide is a swimsuit from the Arena brand, made of pure polyurethane that causes a swimmer to slide through water faster when swimming. One notable example of the efficacy of this suit design is that of Paul Biedermann of Germany who wore the suit in the 2009 World Championships, breaking two world records. The design of the suit covers basically the whole torso and the legs with the impermeable polyurethane, thereby exposing less skin to the water and improving the swimmer's buoyancy and streamlined shape. This significantly reduces the drag on the swimmer as they move through the water.

Technology doping is the practice of gaining a competitive advantage using sports equipment. The World Anti-Doping Agency (WADA) considers prohibiting technologies if they are "performance-enhancing" or "being against the spirit of the sport". In 2006, WADA initiated a consultation on technology doping which is now officially recognised as a threat, whilst the decision to allow or ban a new technology, specifically relating to sports equipment, is the responsibility of each sport’s own governing body.

<span class="mw-page-title-main">History of competitive swimwear</span>

The history of competitive swimwear has been dominated by concerns over public nudity in the first half of the 20th century and by efforts to reduce water drag in the second half. Those efforts initially led swimmers to reduce the early sagging one-piece swimsuits down to briefs only. With the development of new materials that tightly fit the body and offered lower resistance to water than human skin, this trend was reversed to a complete body coverage from heels to neck and wrists. FINA banned full-body suits from competition effective from 1 January 2010, stating that it "wishes to recall the main and core principle is that swimming is a sport essentially based on the physical performance of the athlete".
