Several reasons.
The compression of the fabric, slightly reduces muscle vibrations, leading to enhanced performance.
The wind resistance is reduced. Without the other factors a naked shaved body would have least drag through the air, but in some cases the actual fabric itself can be engineering to be less drag than this ideal. Imagine a flag, flapping in the wind, well you don't want clothes that are like a flag.
It reduces friction, between body parts, legs, armpits, etc and moves with the body instead of moving over and chaffing the body. This can be a problem for sensitive parts of the body eg, nipples.
It provides cooling for the body, the close fitting thin fabric helps wick the sweat, the body's cooling mechanism away from the body, enhancing the cooling effect. Of course there can also be incorporated panels of thicker or lined Lycra to keep warm as necessary.
It stretches and is lightweight. Think about it, try bending over into the starting blocks of a sprint race wearing nomal jeans (without Lycra) and a cotton button up shirt. Then imagine how much easier it would be without the heavy restrictive clothing, that probably prevents you actually getting into that position without hoisting you waistband, or shuffling your shirt around your shoulders.
Basically it is the most practical, comfortable material, and looks good too, superman, power girl, Spider-Man all the superheroes.
Lycra is often used in articles of clothing, particularly sportswear where a close fitting garment is required for less wind resistance. Lycra is also used in underwear.
Lycra is good for sportswear
Lycra is not known for its insulating properties. It is a synthetic elastic fabric that is commonly used in sportswear and swimwear for its stretch and comfort properties, rather than for its ability to provide warmth. For insulation, materials like wool, down, or synthetic insulated fabrics are typically more effective.
Lycra probs wonts be used cause their i nothing else to use it for.
Lycra is an artificial fabric used in Feminine togs, like Nylon or Spandex, it is not a person"s name, Laura is, not Lycra.
no
The tight-fitting material commonly used for sportswear is called spandex, also known as Lycra or elastane. This fabric is known for its exceptional elasticity, allowing for a snug, body-hugging fit that enhances comfort and freedom of movement during athletic activities. Spandex is often blended with other materials like polyester or nylon to create moisture-wicking and breathable sportswear suitable for various sports and fitness activities.
Lycra, a trademark of Invista (formerly part of DuPont) make Spandex.

Lycra is a brand name for spandex. Spandex is a synthetic fiber made primarily from a polyurethane polymer. It is a competitor to the natural material latex.
To calculate the Lycra percentage in a yarn, you first need to determine the total weight of the yarn and the weight of the Lycra component. The Lycra percentage is calculated by dividing the weight of the Lycra by the total weight of the yarn, then multiplying by 100. For example, if you have 10 grams of Lycra in a 100-gram yarn, the calculation would be (10g / 100g) × 100 = 10% Lycra. Yarn count, on the other hand, is typically expressed in terms of weight per unit length, and can be calculated using specific formulas depending on the measurement system (e.g., metric or imperial) used.
Probably Lycra, nylon or polyester
