A high-tech swimsuit is an advanced swimsuit designed specifically for competitive swimming, often featuring high-tech materials and innovative designs designed to enhance a swimmer's performance and speed in the water. High-tech swimsuits are a revolutionary advancement in the world of competitive swimming. These swimsuits are designed using cutting-edge technology and materials to enhance performance and improve swimmers' speed in the water. One of the key features of high-tech swimsuits is their hydrodynamic design, which reduces drag and enables swimmers to move through the water with greater efficiency. These swimsuits are made from lightweight, low-drag materials that help streamline a swimmer's body in the water, such as polyester fiber, spandex, etc. High-tech swimsuits usually have excellent compression performance, providing additional support and muscle compression, which helps to reduce muscle vibration and fatigue during swimming. In addition to their hydrodynamic design, high-tech swimsuits also utilize compression technology to improve muscle support and reduce fatigue during races. The tight fit of these suits helps increase blood flow to muscles, allowing swimmers to perform at their best for longer periods of time.
 
While high-tech swimsuits have been met with controversy in competitive swimming circles due to their perceived advantage over traditional swimsuits, there is no denying the impact they have had on the sport. Swimmers who wear these suits often experience significant improvements in their race times and overall performance.
 
A sharkskin swimsuit is a type of competitive swimwear designed to mimic the texture and hydrodynamic properties of a shark's skin, which is a type of high-tech swimsuit. These swimsuits are engineered to reduce drag in the water, helping swimmers to move more efficiently and potentially swim faster. Sharkskin swimsuits are typically made from high-tech, lightweight, and water-repellent materials. These materials can include a combination of polyester, elastane, and other synthetic fibers designed to provide a tight, streamlined fit.
 
However, in July 2009, during the World Championships, FINA made the decision to ban high-tech swimsuits. At this time, the development of high-tech swimsuits was at its peak. Many companies have developed various high-tech swimsuits aimed at improving athletes' performance. Nonetheless, FINA decided to globally ban high-tech swimsuits in May 2010.
 
In the past ten years, high-tech swimsuits have gone from prosperity to complete ban. During this period, many top athletes have used high-tech swimsuits to achieve many world records; experts had many discussions about whether such swimsuits should be allowed to be used. Ordinary spectators also had a lot of disputes over whether it was reasonable for different athletes to use high-tech swimsuits. Finally, during the 2009 World Championships, FINA as an official gave new regulations on this. In the decision issued by FINA in 2009, it not only mentioned the ban on high-tech swimsuits in subsequent competitions, but also stipulated what kind of swimsuits athletes should prepare. FINA stipulates that from 2010, the swimsuits worn by all athletes participating in international competitions must be textile and cannot cover the limbs. High-tech swimsuits are prohibited in international competitions, but the world record achieved while wearing high-tech swimsuits will be maintained before that.
 
In fact, regardless of the type of competition in the Olympic Games, the focus is on fairness and justice. For participating athletes, their goal is to achieve the best results within the rules’ scope. In international competitions, the athletes who finish last are typically top, talented and experienced. Their results may not vary much. Sometimes even a small factor can determine the outcome of a competition. As an auxiliary tool, high-tech swimsuits can help athletes surpass their own limits, which is beneficial for setting records. However, the use of this tool is not inherently fair. Considering the entire competition format, one could argue that the use of this kind of swimsuit constitutes a form of cheating. Athletes who train equally hard may achieve completely different results because of the difference in a swimsuit. This goes against the spirit of fairness and justice in sports competition. This may be the reason why FINA chose to ban it after considering various factors.
