Abstract

Canoe polo is an increasingly popular discipline requiring both kayaking and ball handling skills. While the kinematics of the upper body during throw have been investigated for several overhead sports, the canoe polo throw has still to be studied. The aim of this study is thus to analyse the canoe polo throw kinematics in terms of angles and inter-articular sequencing to understand its specificity. A secondary aim is to investigate whether adding pelvis mobility has an impact. Nineteen male players of canoe polo were equipped with reflective body markers for the throw analysis. They performed 5 throws with the pelvis fixed and 5 throws with an additional pelvic mobility in rotation around a vertical axis. Inverse kinematics was performed with OpenSim providing pelvis, trunk and gleno-humeral rotations. Angular velocities were calculated to build the inter-articular sequences relative to these throws. Statistical parametric mapping was used to assess the effect of the pelvis mobility on the throw kinematics. Similar kinematics patterns as in other overhead sports were observed, however a different inter-articular sequence was found for the canoe polo throw with a maximal angular velocity occurring sooner for the thorax in axial rotation than for the pelvis in rotation. While the limitation of rotation of the pelvis around a vertical axis has an influence on the pelvis and trunk kinematics, it didn’t modify the kinematic sequence.
