Sports wheelchairs
A range of disabled sports have been developed for disabled athletes, including basketball, rugby, tennis, racing and dancing. The wheelchairs used for each sport have evolved to suit the specific needs of that sport and often no longer resemble their everyday cousins. They are usually non-folding (in order to increase rigidity), with a pronounced negative camber for the wheels (which provides stability and is helpful for making sharp turns), and often are made of composite, lightweight materials. Even seating positions may be radically different, with racing wheelchairs generally used in a kneeling position. Sport wheelchairs are rarely suited for everyday use, and are often a 'second' chair specifically for sports use, although some users prefer the sports options for everyday use. Some disabled people, specifically lower-limb amputees, may use a wheelchair for sports, but not for everyday activities.
