Abstract
Simplified marker sets for the calculation of whole body centre of mass (CoM) location and associated variables (velocity, touchdown distance and turn of CoM) used in the analysis of bend sprinting performance were examined. CoM related variables were compared between a whole-body (13 segment), lower limb and trunk and lower limb model. Both simplified models showed strong agreement with whole-body CoM (Intraclass correlation: 0.873 - 0.998). The lower limb and trunk model (LLT) was the most accurate representation of whole body calculations, with acceptably low differences in all variables examined. Therefore, the LLT model is recommended for future use.
