MODELLING NON-PLANAR PELVIS AND TRUNK ROTATIONS IN A PLANAR SIMULATION MODEL

Paul Felton, Mark King

Abstract


In whole body planar simulation models the bilateral hip and shoulder joint centres are assumed to be symmetrical. Non-planar rotations of the pelvis and trunk can cause these joint centres to be asymmetrical. In order to allow asymmetrical hip and shoulder joint centres in a planar simulation model a massless segment method was used in an angle driven simulation model of the front foot contact phase of fast bowling. The model was customised to an elite fast bowler by closely matching three performances and evaluated. It was concluded that the massless segments method to allow asymmetrical hip and shoulder joint centres within a planar simulation model was suitable to reproduce predominately planar movements.
