The Throwing Frames (chairs) is one of the technologies used by physically disabled athletes to perform well in athletics throwing events (javelin, discus, shot put and club), to execute throwing from the sitting posture. Throwing Frames have replaced the wheelchairs in athletics throwing events. Unlike wheelchairs, throwing frames do not have wheels. They are more robust than wheelchairs and easier to tie down to a stable position with more convenient balance and control. The throwing frames must adhere to the standard of the paralympic competition to be used at those events.
