This study aimed to develop and evaluate an image-based method of obtaining anthropometric measurements for athlete-specific inertia modelling. Anthropometric measurements were obtained directly from five athletic performers and indirectly from digitization of whole-body still images. The direct and image-based measurements were used in Yeadon`s (1990) inertia model. The mean absolute accuracy in predicted whole-body mass achieved using the direct and image-based approach was 2.10% and 2.87%, respectively. The presented approach provided a successful alternative to direct measurement for obtaining anthropometric measurements for inertia modelling of athletic performers. The method offers a valuable solution for obtaining measurements from elite athletic performers for whom time-consuming data collections may be undesirable.
