Do Compression Sports Clothes Really Improve Performance?
Compression garments are pieces of clothing that fit tight around the skin. In medical contexts, compression garments provide support for people who have to stand for long periods or have poor circulation. These come in varying degrees of compression, and higher degree compression sleeves, such as sleeves that provide compression of 20-30 mmHg or higher, typically require a doctor’s prescription. Compression garments worn on the legs can help prevent deep vein thrombosis and reduce swelling, especially while traveling. In sports, form-fitting compression sportswear, usually made of spandex, is commonly worn by athletes and in exercise to prevent chafing and rashes. Depending on the material used, compression garments can be designed to keep athletes cool or warm depending on the requirements of the sport. One small study of compression shorts found no change in sprint time, but found some gait changes that might reduce injuries. Another study of calf sleeves found no change in sprint times and gait; larger reviews have found no evidence that compression garments can improve athletic performance beyond the placebo effect
