The movement occuring at your joints during a netball shot is called CONDYLOID joint movement. Condyloid joints allows flexion, extension and circumduction movements or motions. In example shooting a ball requires the foot to be everted and inverted and the vertebral column to be flexed.
A lack of flexibility is a risk factor for athletic injuries or cramps.
