Sturdier than typical bras, they minimize breast movement, alleviate discomfort, and reduce potential damage to chest ligaments. Many women wear sports bras to reduce pain, and physical discomfort caused by breast movement during exercise. Some sports bras are designed to be worn as outerwear during exercise such as jogging.The design challenges of Sports BraSports 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.The most common sports bra is basically designed like a tank top with the bottom half cut off. Other designs use gel and water pads, silver fibres, and air bags. A stitchless bra was made by Wacoal, was molded, compressed, and shaped. A compressed bra is designed to push the breasts against the chest to reduce movement and bounce. Other bras are knitted in circular patterns, giving varying stretch and support. A common design uses a stretchable, absorbent fabric such as Lycra designed to reduce irritation by drawing perspiration away from the skin.Sports bras are also worn by women after certain surgical procedures. In those situations, a front-closing sports bra with a compression, seamless cup is recommended for healing and comfort. Certain fabrics such as Lycra have been found to help reduce swelling and help "even-out" a bustline that has been altered by a surgical procedure.Sports bras are also manufactured for men with large breasts to enable them to take part more comfortably in physical activity. Some descriptions used euphemistically to describe bras for men are chest binders, compression vests or shimmels.Levels of control of Sports BraDifferent physical activities require different levels of breast control. Yoga, walking and gardening require only "ligh" control; bicycling, power walking and hiking require "moderate" control; tennis, soccer and jogging requires "firm" control; and running, intense workouts, boxing and horseback riding requires "maximum" control. Some female athletes are concerned that a sports bra may interfere with breathing, but even though increased pressure on the rib cage has been demonstrated, no significant effect on breathing can be shown.
