[Truncated abstract] In cricket, the bowler propels a ball using a straight arm (permitted minimal extension) in an overhead fashion to a batsman situated approximately 20m away, who attempts to strike the ball in order to score runs for their team. Cricket bowling can be generalised by two types of bowlers; fast bowlers, who primarily use high ball speed, and spin bowlers that attempt to impart spin on the ball causing it to bounce in different directions. There has been numerous studies investigating the kinematics of fast bowling in cricket, but there is a paucity of objective literature on the spin bowling action due to the complex rotations of the upper limb necessary to develop ball velocity and rotation. One primary reason is that three dimensional (3D) analysis of upper limb movement is difficult due to the high degrees of freedom and ranges of motion of the associated joints. Furthermore, existing methods do not allow measurement of the kinematics of this highly dynamic task to be performed in an ecologically sound environment. The complexity is further compounded as the upper limb does not perform regular cyclical movements like the lower limb does with gait. Therefore, this makes it difficult to determine what
