Young Sport Girl Wearing A Sports Bra

Design and history
The first commercially available sports bra was the "Free Swing Tennis Bra" introduced by Glamorise Foundations, Inc. in 1975. The first general exercise bra, initially called a "jockbra", was invented in 1977 by Lisa Lindahl. Her sister, Victoria Woodrow, called to complain about her bad experience exercising in ordinary bras. She was frustrated by runaway bra straps, chafing skin, and sore breasts after running. Hinda Miller and Lisa Lindahl cut up a pair of jockstraps and sewed them together into a bra; and marketed the garment as the Jogbra.
In 1990 Playtex purchased Jogbra from Lisa and her partners. This was followed by research by Christine Haycock, associate professor of surgery at the University of Medicine and Dentistry of New Jersey. She measured breast movement of women running on treadmills. Sought out by bra manufacturers for her expertise, she advocated wide bottom bands for extra support and firm straps that minimized breasts bounce. Renelle Braaten, a Montana hairdresser, struggled to contain her double-Ds while playing racquetball and volleyball. Unable to interest mainstream bra manufacturers, she collaborated with freelance apparel designer Heidi Fisk, and founded Enell Incorporated. After considerable lobbying, she persuaded Oprah Winfrey in 2001 to try her bra. This led to very positive reviews in O: The Oprah Magazine, a 2001 appearance on The Oprah Winfrey Show, and a huge surge in orders.
Sports bras can either encapsulate or compress breasts. Bras that encapsulate breasts have molded cups, while compression-type bras restrict movement by flattening the breasts. Encapsulation-type bras generally are more effective at reducing discomfort, but some women prefer compression designs that enhance their perception of modesty.
